Generac running but no power

Generac running but no power DEFAULT

Perhaps the most frustrating thing that can happen when your power goes out is to fire up your generator without a problem and then find that it isn’t producing any electricity.  The engine is purring just fine but it can’t even light up a single lightbulb to lead you back into the house to tell your family that things are going to be dark for a while. 

At that moment it’s understandable that you’d want to buy a new generator and sell the defective generator for scrap.  There are, however, a few things you might want to look at before you go and get yourself a new one.  

Here are 6 common reasons your generator is not producing electricity:

  • Tripped Breaker
  • Loss of Residual Magnetism in the Alternator
  • Brushes Worn
  • Defective Breaker
  • AVR defective (Automatic Voltage Regulator)
  • Capacitor Defective

Let’s cover each of these briefly with what you can do to either fix or replace what is needed to get things back up and running as soon as possible!

Tripped Breaker (or Fuse)

First and foremost, if you’re not getting power to your appliances after you’ve turned on the AC power switch from your generator, then you should check to verify that you don’t have a tripped breaker. 

There are two types of breakers that you might encounter: 

  1. Circuit Breaker (fuses)
  2. GFCI Breaker

The circuit breakers (or fuses) are going to protect you from overloading the amp capacity of the generator.  For example, if you have a 1kw generator and decide to try to power a microwave you are going to trip a circuit breaker (and hope that that’s all the damage that you do). 

GFCI breakers are designed to trip when they sense that there isn’t enough power completing the circuit on the circuits designated route.  Remember, electricity is always trying to find its way to “ground” (earth) and will take the path of least resistance.

For example, if you have an extension cord running from your generator that has a small nick in the cord and that cord happens to be running through the wet grass as it stretches to your house.  The electricity will reroute itself to the earth via the water and will not complete the circuit. Your GFCI breaker will trip.

Another common way to trip circuit breakers is to use the wrong gauge of wire for what you’re trying to power (using too small a diameter), or plugging multiple cords together. 

Keep in mind that it might just be a particular item that is tripping your breaker (either the circuit or GFCI) and it might not necessarily have anything to do with your generator.  Test other items out, and even items of comparable wattage to see if the affected breaker still trips.

If it is a true emergency and you cannot get a generator to work and you are certain that it is the breaker that is at fault, you can technically bypass your breaker altogether.  Before I continue, please read the next sentence more than once to get my feelings about the matter.

I DO NOT RECOMMEND BYPASSING YOUR CIRCUIT BREAKERS AND YOU ARE RESPONSIBLE FOR ANY DAMAGES, FIRE, OR DEATH THAT MAY OCCUR!

I’m just including this video to show that it can be done in a pinch and it is imperative to replace your defective breaker as soon as possible.

Loss of Residual Magnetism in the Alternator

Once you’ve verified that your breakers are not the problem, the next thing to do is see if you’ve got a loss of residual magnetism in your alternator.  Electromagnets, like those in your generator’s alternator, need a bit of residual magnetism to be “primed” to get the electrical generation process going, for a lack of a better term.  

Sometimes, after sitting unused for extended periods, allowing the generator to run out of gas with a load on it, or turning off the generator’s engine start switch with a load on it, a generator’s residual magnetism can be neutralized or lost.  

Luckily, there are a few ways to fix this problem.  My favorite involves something I saw when growing up and it involves using nothing more than a corded drill.  

With the generator running, the AC power turned on, and the drill plugged in, try to start the drill.  We are assuming that it will not run. Otherwise, you wouldn’t be reading this.

Now, make sure the drill is set to drill in the forward position (the chuck will turn clockwise if you’re holding the handle and it’s facing away from you).  Then, press down on the trigger with your right hand and spin the empty drill chuck (do not have any drill bit inside!) backward, or counter-clockwise. Do this in a fast and flicking motion so that your hand is barely grabbing it during the process and is clear of the chuck after the spin.  

You do not want your hand getting caught, and that is the reason I would discourage wearing gloves, but that’s your choice. I certainly wouldn’t want loose-fitting gloves.

It should only take 1-3 twists and your drill will start working in your hands.  

Congratulations, give yourself a pat on the back!  You’ve just “flashed the field”, as they say!

Here are some helpful visuals below, depending on what tool you might have around you.

Brushes Worn

This is pretty much the last thing that you can easily check visually without learning how to use a multimeter to check resistance and voltages.  

When you remove the cover to your generator’s alternator, you will see something relatively similar to what’s in the picture. 

Usually, right above the bearing, you will see two spade connectors that connect to the brushes (carbon material that makes contact with the rotor). They are held in place by a screw.  With the generator off, take a picture of how everything looks and the orientation of the wires and remove the spade connectors. Then, remove the screw.  

Pull out the brush assembly and check to see if they look damaged, broken, or are sticking. The brushes are small rectangular carbon pieces that can be pushed into the assembly but want to pop back out.  

Check the assembly itself for any burn marks or anything that just doesn’t look right.  

More than likely your brushes are fine, but if they aren’t, go ahead and replace them. 


If you don’t have the knowledge of how to use a multimeter to measure resistance and voltages, then the following problems are going to be more on a “replace and pray” methodology.


Defective Breaker

Without learning how to use a multimeter, the video below is a good demonstration on how to change out a circuit breaker if you suspect it is the problem (constantly tripping despite the appliance, cord, etc.).  If you’re not able to watch the video below, the steps are outlined below.

  • Remove the spark plug to prevent accidental starting
  • Remove whatever screws or nuts that are holding the outlet housing in place
  • Disconnect the power harness
  • Open the outlet housing cover when free from the generator
  • Take note of the wire orientation on the breaker you are replacing
  • Use a flat-head screwdriver to press on the tabs to release the breaker
  • Reuse the breaker protective cover from the old one, if applicable
  • Snap the new breaker in place and reconnect the wires
  • Reverse the prior steps to put everything back together

AVR defective (Automatic Voltage Regulator)

If you suspect that your AVR is defective, they are luckily an easy fix but will probably cost you $100. They come in all shapes and sizes but are oftentimes located in the bottom left side when you remove the alternator cover. 

  • Unplug your spark plug to prevent accidental starting
  • Remove the bolts or screws holding your generator’s alternator cover in place
  • Disconnect the two spade connector wires to the brush assembly (take a picture to remember which one goes where!)
  • Unscrew the screws holding the AVR in place
  • Disconnect the quick-connector
  • Connect the new AVR to the quick connector and follow the steps in reverse to reassemble

Capacitor Defective

There are many shapes, locations, and sizes of capacitors that might go bad on you.  Below are three different videos with three different capacitor issues.

This one has a cylindrical capacitor located under the cover to the alternator.  It isn’t mentioned in the video, but whenever you’re dealing with capacitors you need to be very cautious.  They are storage units for AC power and if your fingers bridge the two nodes on the end you will get a shock (which can be severe or deadly with certain capacitors).  I don’t know the particulars on this one, and maybe it wasn’t enough to do any damage and that’s why it wasn’t mentioned.

This next video shows the brush rectifier which is attached to the brushes as being bad.  The blue part that went bad on the rectifier on his old unit was actually a capacitor.

This final video features another capacitor but this one is located under the outlet housing.  The gentleman refers to the melted unit as an AVR (since it did have those letters on it) but it is actually a capacitor.  So, when all else fails, take a look under your outlet housing for anything that looks burnt or melted.

generac generator runs but has no electrical power

Generac is a famous company that is from America. They focus on manufacturing generators for their users. The best thing about these is their portability. Though, some models are made for heavy-duty use. If you are someone who wants to install the product in your vehicle. Then it is recommended that you use the portable ones.

These have numerous features on them and are lightweight. This makes it easier for users to transport and store them in your vehicle. Though, it is important to note that there are some issues that the user can run into.

Recently, Generac generator users have been complaining that it runs but has no electrical power. This can be quite difficult to deal with which is why we will be using this article to provide you with some fixes that can be used.

Generac Generator Runs But Has No Electrical Power

  1. Check Circuit Breaker

When you are trying to start your generator and there is no electrical power coming from it. Then the first thing that you should check is the circuit breaker on it. These devices are installed on appliances like these as a security feature. The breakers will cut the connection if they notice that the current flowing through them is acting abnormally.

This can be from a low voltage, alternatively, you might have accidentally plugged in too many appliances. These can overload the device which will then cause it to stop the connection. Some circuit breakers identify their state through colors. However, if the circuit breaker in your Generac generator does not show this. Then you can connect a voltmeter or multimeter to it.

This will show you the reading of current coming to the breaker. If you notice that the values are normal then start your breaker again. This should allow the current to pass through it easily now.

Though, in some cases, the circuit breaker can get burnt out. If this happens, then the user will have to replace the breaker completely. Make sure that you check the voltage requirements on these before purchasing one. These will help you to avoid any further problems.

  1. Clean Off Device

Sometimes the problem can be that your generator has a lot of dirt and rubble stuck in it. The fuel in your devices can get dirty over time. Which will then start to get thick and clog the valves in the equipment.

Considering this, you must clean off your generator frequently. The dirt in these can prevent them from supplying electricity to your ports. Start by removing the fuel in your generator and completely take off any connection on it.

These will prevent you from getting electrocuted. You can then use seafoam or any other similar cleaner to clean off your device. Many companies manufacture these products but make sure that you choose a reliable one.

After completely cleaning off the device, remove the liquid carefully. Once you are ensured that none of it is left in your generator. You can now plug it back in and test if it works fine.

  1. Check Fuel

Generators use fuel as their source to generate power. It should be obvious that you should check the fuel level in your device if it is not performing correctly. Though, the thing that people do not know about is that.

These generators require you to keep the fuel level above 1/3rd of the maximum capacity. If the oil starts to drop below this then you might notice that the generator switches off. If not then it will stop supplying current to your vehicle or appliances. This is why it is important to keep the generator filled with fuel at all times.

Additionally, keep in mind that you should wait for some time after you have filled up your device. The fuel will take some time before the generator can start using it correctly. Another thing to consider is that you switch off your device when filling it up.

Pouring in fuel when the generator is running can be dangerous and might even cause the device to short circuit. If you are still experiencing any issues then it is recommended that you contact the company. They should be able to fix the equipment for you if required.

Loss of Generator Production?

Generators are large, intricate, power generating machines that we heavily rely on to keep the world running when a loss of utility power occurs. But what do we do if our generator stops producing that power?

One of the most commonly searched troubleshooting questions about backup generators is:

“Why is my generator running, but not producing electricity?”

We asked our technicians for their expertise on the subject, and here’s what they had to say.

Generator Inspection and Repair

Loss of Residual Magnetism (Most Common)

Generators work by moving electrical conductors through a self-created magnetic field. However, generators do not contain any magnets. The magnetic field referred to is created by taking some of the generator output voltage, converting it to DC, and feeding it into a coil to make an electromagnet.

Generators start up by using something called residual magnetism. This is a small amount of magnetism left over from the magnetic field that was created the last time the generator was running. This little bit of leftover magnetism is enough to produce a small amount of electricity. This small amount is used to create an electromagnet. As the engine begins to turn this electromagnet, moving its electric field, through the stator windings, your generator will produce more power. However, if residual magnetism is lost, your generator will produce no power at startup.

Loss of residual magnetism may be caused by the generation being out of use for a while, having a connected load when the generator is shut off, running your generator for too long with no load, or if your generator is new, it could have lost residual magnetism from long distance transportation vibration.

You can combat loss of residual magnetism by always running your generator with a load and disconnecting that load before you turn the generator off. There are ways to regain residual magnetism if it is lost, but they are not covered in this article.

Poor Connections

To fix poor connections, clean all ports from any particles, debris, or blockages and ensure all connections are tight. This is an important step in maximizing the reliability of your generator.

Excitation Circuit Wiring Error or Blockage

If a circuit wiring error is the issue, identify the error and correct it.

If an excitation circuit is blocked, use a multi meter to find the blocked excitation winding and reconnect it. For failure caused by just poor contact, you can polish the surface oxide layer until smooth, then the loose connection nut and bolt should be able to connect firmly.

Tripped Breaker

Find the reason the breaker has tripped and remedy it before starting the generator again.

Generator Inspection and Repair

Broken or Grounded Generator Excitation Winding

Use a 500V ohmmeter to check the ground insulation of the excitation winding, find out the ground point, and use a multi-meter to find the broken winding and restore it.

Worn Brushes

This is an easy fix: Simply replace the brushes.

Defective Breaker

Remove the spark plug to prevent any accidental starting. Then remove any screws that are holding the outlet housing in place. Disconnect the power harness, open the outlet housing cover, and take note of the wire orientation on the breaker you are replacing. Using a flat-head screwdriver to press on the tabs to release the breaker, remove the breaker protective cover from the old one. Finally, snap the new breaker in place and reconnect the wires. Reverse the prior steps to put everything back together.

Defective AVR (Automatic Voltage Regulator)

Unplug your spark plug to prevent any accidental starting. Remove the bolts or screws holding your generator’s alternator cover in place, disconnect the two spade connector wires to the brush assembly (take a picture to help you remember what goes where). Remove the screws holding the AVR in place, disconnect the quick-connector, connect the new AVR to the quick connector and follow the steps in reverse to reassemble.

Defective Capacitor

Remove the capacitor from the generator and discharge any leftover charge. Take a reading from the capacitor using a multimeter. The reading should be +/- 5uf of the specified rating printed on the side of the capacitor. If not, it should be replaced.

Generator Repair - Troubleshooting - Runs But No Power

Why is My Generator Not Producing Power?

FAQ

When your generator breaks it’s hard to not despair. We’ve found ourselves panicking that we’ll have to return to the dark ages. We’ll have to learn how to hunt, to make our own clothes, buy a cow… 

We realize we might have been overreacting a little bit, but generators no longer producing power can cause a lot of people to panic. 

So, what do we do when our generator doesn’t produce power? Is there anything we can do to work out what the problem is? Is there any way to fix our own generators? 

Well, today we’re going to talk you through the most common reason generators stop producing power. We’re also going to teach you a simple trick to fix that problem.

The Cause – Loss of Residual Magnetism

If your generator is still running but not producing power, 9 times out of 10 this is due to a loss of residual magnetism. 

What does that mean?

To create power our generators move electricity through a magnetic field. Generators themselves do not have magnets in them. So, they create their own magnetic field. 

They do this by converting some of the power they produce into a DC current. They then run this current through a coil, turning it into an electromagnet. 

After you have used your generator it holds onto some of this magnetic field. We call this Residual Magnetism. The generator uses this residual magnetism to help it being producing power the next time it starts up. 

Without this residual magnetism, it cannot produce power and do its job. Despite its engine still running, it will not produce any power. 

How is Residual Magnetism lost?

There are a few things that lead to the loss of residual magnetism. 

Firstly, lack of use can cause a generator to lose residual magnetism. Over time the reserve of magnetism is slowly depleted. Until it eventually runs out. 

Another cause of loss of residual magnetism is keeping things plugged into the generator when you turn it off. If the generator is powering a load when turned off the last of its magnetism will be sucked into the load. 

Finally, the third main cause of loss of residual magnetism is to leave the generator running for too long without plugging it into anything. This can cause the electromagnetic field within the generator to shut down. 

How can that loss be prevented?

There are a few things you can do to prevent your generator from losing its residual magnetism. 

Make sure to use your generator regularly. This will keep its residual magnetic reserve strong and full. 

Remove all plugged in loads from the generator before shutting it down. This will help the generator to maintain its own magnetism. 

When running your generator, try to keep it plugged into something unless you are about to turn it off. This is one of the best ways to prevent your generator from losing its residual magnetism.  

It’s already stopped producing power, how can I fix my generator? 

Obviously, the tips above cannot help you if your generator has already stopped producing power. But they will help you prevent it from happening again. 

What you will find helpful is this next section, where we talk you through two easy ways to get your generator producing power again. 

12+ Vault Battery Method 

For this method, you will need some rubber gloves, a light, and a 12+ vault battery. 

Start by finding the voltage generator within your generator. There will be two brush wires plugged into it. One will be red. The other will be either black or white. 

Unplug both of the wires. Plug the black or white one into the generator’s ground battery terminal. Plug your light into the generator and start the motor. 

Take the red cable from your 12+ vault battery, and connect it with the red brush cable. Hold both against the voltage generator terminal for 3-5 seconds. 

Remove the battery wire. Plug the two brush cables back into their original sockets. Everything should be working again. 

Tip – make sure to unplug the brush wires from the automatic voltage generator. Otherwise, you could fry your generator. 

Tip – Do not touch the Automatic Vault Generator with any other wires. Doing this could lead to your receiving an electric shock. 

Electric Drill Method

This is a super easy method for testing if it is the loss of residual magnetism that is causing your problem. Even better, if your theory is right it will fix your generator in the process. 

Plug an electric drill into the receptacle of the generator. Make sure that you have the drill in a forward position. Press down on the trigger of the drill. 

Now, start your generator. Then start to release the drill’s trigger. You want to be spinning the drill’s clip in reverse. 

If the problem is with loss of residual magnetism then doing this will wakeup the magnetic field in the generator. The drill will turn on and start spinning. The generator will now produce power. 

If this doesn’t work, try spinning the drill in the other direction. You may have your reverse switch positioned backward.  

Tip – Make sure that nothing is attached to the drill bit when doing this method. The drill will turn itself on as soon as the generator’s field is woken up. It will start spinning, as will anything else attached to the drill bit. 

Tip – if this does not work you should try replacing your Automatic Voltage Generator. As that is the next most likely cause of your problem.

Why does this method work? 

When run backward, an electrical drill can function as a mini generator. 

The drill has small magnets that it uses to produce its own power. Using this method you can transfer some of that magnetism from the drill to the generator. 

It passes down the wires and flows through the coil in the generator. This coil becomes an electromagnet again and the generator will start producing power.

But no power generac running

Have you ever wondered why your RV generator runs but not producing any power? Look no more.

We`ve got you covered.

When you are away from the beaten tracks with your RV, the primary source of electricity will most likely be the generator you have installed in it.

It will provide power for all of your appliances in your motorhome or camper trailer, on which depends whether your trip in the wilderness will be enjoyable or ruined.

Not many things are unpleasant as slowly steaming in your RV while your perishables are going bad because your AC and fridge are not working due to lack of power.

The role of the generator is to provide you with electricity by using the internal combustion engine combined with a generator. But sometimes it can happen that it is running and not producing any power.

So, why your RV generator runs but not producing any power? If your RV generator is running but not generating power, you need to check the following steps, including:

–           Step #1: Check generator’s breakers

–           Step #2: Check output leads

–           Step #3: Check again circuit breakers

–           Step #4: Check voltage at terminal blocks

–           Step #5: Check the main fuse box of the RV

–           Step #6: Check the generator transfer switch

–           Step #7: Find an appliance that is shorting

–           Step #8: your generator was overloaded

So, keep on reading to find out when and why this can happen, and how to fix it.

Why Generator Can Run Without Power In RV?

The role of an electrical generator in an RV is to use chemical energy in the fuel to produce mechanical energy which is then in turn transformed in the alternating current.

The chemical energy is transformed into mechanical energy the same way as in your car or RV when cruising down the roads, with an internal combustion engine.

There are two reasons why a generator can keep on running while no AC power is reaching your appliances.

The most common one is some type of break in the electric lines, and usually is not a reason for great concern.

The second reason is a faulty alternator on the engine of your generator.

Both of these issues make no impact on the generator engine’s ability to run properly and safely, and thus it doesn’t shut down.

How To Fix Lack Of Power

The generator is the main source of electrical power needed for all of the appliances you can have in the RV when there is n shore power outlet to hook it up to.

If your appliances lose power, they will not be able to provide you with their benefits.

This can be a very alarming situation if you are not experienced with the repair of generators.

But, there are several causes that can lead to this situation, and none of them is an indication of a faulty generator.

And you can rest assured that the generator itself is working properly.

So, let’s move on to finding and fixing the cause of this type of behavior of your RV generator.

Troubleshooting The Problem

As I have said above, in general, there are two reasons why a generator may keep running but your RV still not receiving the 120 volts alternating current electricity.

It can be either a faulty alternator or a break in the power lines after the generator.

Because, in essence, in both of these situations everything is OK with your generator, it will continue working.

But, it still remains to precisely diagnose and fix the problem.

So let us move on with the actual troubleshooting of the problems by starting with the one which is very often the easiest one to diagnose.

Faulty alternator

In case that the alternator has failed, most generators will enter a so-called engine running only or ERO mode.

Some generators have a very simple and elegant system for notifying a user of any fault during the work.

Some have an indicator light that continuously lights when everything is properly working.

In case that there is some fault, it will start blinking a repeating sequence that signifies the fault code of the problem.

“In case that there is a problem with the alternator and it switches to ERO mode, this indicator light will start rapidly blinking on and off.”

The most common problem with an alternator is blown diode, which can be very easily be diagnosed and repaired by virtually any car shop.

So, if you see the indicator light blinking rapidly, your best course of action is to shut down the generator and take it to a shop.

Other makes and models of generators have a different way of signaling the problem with the alternator, so the best you can do is to consult the user/operator manual to see how exactly it is reported.

In case that everything is OK with the alternator, some generators will have the indicator light on continuously.

Some other types will have a different way to signal that everything is working the way it should, and you should consult the manual for your model for the exact way it will do it.

Electric Lines Break

If you don’t have much experience with electricity, this can sound alarming.

But most of the time it means that the circuit breaker was tripped somewhere, which is its function anyway, to break the circuit under certain conditions.

It doesn’t necessarily mean that you have faulty wiring, so let’s get on with troubleshooting them first, as they are the most likely cause.

Step #:1 Check generator’s breakers

Before you start doing anything you must turn off the generator by pressing the STOP button, or whatever is the correct stopping procedure according to your user manual.

Once it is stopped, you should remove the access panel and find where are two breakers that protect the generator from overloading and short circuits.

On some models, these two are usually on the side of the plastic housing of the controls.

If any of these two was tripped, you should reset it and turn the generator back on.

If nothing happens, something led to the temporarily overloading of your generator, and you should try to remember whether you have turned on some device just before you have lost the power.

But, if right, as you start it the breaker, gets tripped again, you have a short circuit and should move to Step #7 to diagnose which device is to blame.

Step #2: Check output leads

If neither of these two breakers was tripped, you should check the output leads of the generator, chances are that some have come off due to vibrations.

If everything is tight and secure, move to Step #3.

Step #3: Check again circuit breakers

In case that circuit breakers are not tripped, they might be faulty.

So, you should check them for continuity at both terminals with a multimeter.

In case that there is no continuity on one of them, it means that it is faulty and you will need to replace it according to the manual for your particular model of generator.

Step #4: Check voltage at terminal blocks

This step is not to be performed if you don’t have experience with testing the voltage of live wires with a multimeter.

120V of alternating current can be deadly if you don’t treat them with respect.

If you have never done it before, you should leave it for a professional, and skip to Step #5 and eliminating other possible causes.

Now that you are warned about the dangers, and if you are skilled enough and know how to treat live wires, here’s what you need to do.

Generators usually have two or three terminal blocks, and you will have to check the service manual for your generator how they are wired.

You will need to check the voltage with the multimeter across them while the generator is running.

If there is around 120V they are OK, otherwise, if any of them reads considerably lower voltage, the wiring needs to be checked whether it is securely connected and if it is so, to be replaced.

If the voltage is around 120V you will need to replace the AC harness, but if there is no voltage, you will need to replace the control assembly because it’s faulty.

Both of these are best left for professional technicians, so taking the RV to a dealership is the best course of action.

If everything is OK, but you still have no power, move to the next step.

Step #5: Check the main fuse box of the RV

In case that everything is OK with breakers and wirings on the generator itself, there are chances that there is a problem in the RV’s systems.

So the next thing you should check whether some breaker was tripped in the main fuse box of the RV, in case that some of them are tripped you should move them back to ON position, and start the generator again.

In case that the same breaker gets tripped again as soon as you restart the generator, it means that some of the appliances are shorting and you should move to Step #7.

In case that everything works fine, you should try to remember whether you had powered some device just before your RV lost power, if so, it was the thing that overloaded the generator and you should try to decrease the number of devices you have turned on.

Step #6: Check the generator transfer switch

Most of the RVs have an automatic generator transfer switch that automatically starts drawing power from the generator when it is started.

If you have easily accessible shore power, you should plug it in to check whether the generator transfer switch is malfunctioning.

In such a case, you will have power in the RV when connected to shore power, but not when connected only to the generator.

In this situation, you will have to take the RV to a shop for the replacement of the transfer switch.

In case that your RV is an older model, it may not have a transfer switch, but the generator needs to be manually hooked up to RV’s system.

“Where precisely it is located you can find in your RV’s manual, but generally, it is a small hatch on the side of the RV, around three feet from the generator’s hatch.”

In case that connecting the RV to shore power trips a breaker, you are dealing with an appliance that is shorting and should move to the next step.

Step #7: Find an appliance that is shorting

When some appliance is shorting it will trip either the generator’s breakers or the RV’s breakers.

And it will do it every time you switch the power back on after resetting the tripped breaker.

Finding that faulty appliance is a very straightforward process, though it can be a bit boring.

You need to unhook all appliances from power outlets, start the generator, and then reconnect the one at the time.

Make sure that at any time you have only a single appliance plugged in.

The faulty appliance will trip the breaker as soon as you plug it in.

Step #8: your generator was overloaded

In case that plugging in and turning on appliances one at a time doesn’t trip the breaker, you should start plugging them one by one, instead of one at a time.

Eventually, after plugging in and powering on one of the appliances, the breaker will trip because you have put too high of a load on your generator.

This can happen for two reasons, either your RV has too small a generator or you are at too high an altitude for the generator to produce its maximum output.

Many generators, especially propane-powered ones, are sensitive to altitudes above 5,000 feet, and their maximum power output can drop by as much as 15%.

Fixing generator power problems

What causes generators to stop producing power?

The most common cause of power loss in generators is due to loss of residual magnetism.

This can be lost naturally if you run the generator for too long with no load.

There are many reasons that can cause generator problems no power, keep reading to find out some of these problems and their solutions.

Running too many power devices at the same time can also trip the circuit breaker.

It may restart fine but after a short built-in delay, you find no power in your camper.

2. Unplug the two wires (the red and black one) connecting the generator brushes to avoid damaging the regulator.
3. Connect the black wire to the ground battery terminal.
4. Plug-in light and start the motor. Ensure the breaker is on. The red wire should be connected to the battery.
5. Remove the wires and replace the plug.
6. Reset the circuit breaker to restore the power in the camper.

By doing this, your generator should produce power again.

Tip: If these instructions do not help, replace the automatic voltage regulator.

Brushless generator not producing power

Make brushless generator produce power again

A brushless power generator is a very compact and convenient source of electric power. It can be irreplaceable in householding.

If you noticed that your brushless generator not producing power check the following:

1. Firstly, check the load. When the value of the maximum voltage exceeded, the unit may simply not give out power because of the trip
circuit.

2. Research the state of brushes.

3. Check the winding integrity. One of the common reasons for the malfunction is damage to the winding.

4. Make sure no short circuit between the windings. This may happen, for example, during a breakdown of insulation.

5. Check for an inter-turn short circuit. You can’t verify it by yourself, a special laboratory device is needed. Luckily, this occurs extremely
rare.

6. Check if the rotor was demagnetized. But only a professional can diagnose this.

All listed advice is very helpful if a brushless generator not producing power.

It is very useful to know all the possible reasons.

Generator low voltage output

A low voltage of generator can happen due to many reasons. Excessive load on the generator is one of the main causes that lead way to the low voltage of the generator.

This condition can be prevented by connecting loads under the capacity of the generator.

One of the causes that give rise to generator low voltage output is due to the low AVR voltage gain set.

The poor voltage from the generator condition can also happen due to a low-speed control set.

Hence try to avoid this condition by setting the value as per the requirement.

AVR feedback from generator VT can give rise to overcurrent drip and low voltage conditions in the generator.

Mechanical issues like improper working of the turbine are found to be a cause of poor voltage conditions in a generator.

Voltage drop conditions can also happen due to under fueled conditions in a generator.

This condition generally happens due to the clogging of pores.

In order to avoid Undervoltage due to under fueled condition, feel free to do the checking of generator condition at the right intervals of time.

Too high voltage: how to determine it and what the effects could be

How to determine a generator’s output voltage?

Different generators have a different value of output voltage and each one has a fixed such. Normally, watts are used to evaluate the generator’s output.

The wattage itself is determined through taking the voltage and multiplying it by the electrical device’s load capacity in amperage.

In a formula, this solution would look like: watts = volts x amps.

What could happen if a generator’s output voltage is too high

A voltage that is too high could potentially trigger overheating which could ultimately lead to early failure in different electronic and electrical items.

Normally, overheating causes an immense, advanced and permanent contamination.

Under different circumstances, some electrical components, like motors, for instance, could benefit from slightly higher voltages since a higher voltage could reduce the current which usually results in lower heat exhaust.

Cooling is a key factor in preserving electrical (as well as electronic) items’ endurance and durability.

GENERATOR RUNNING BUT NO POWER IN HOUSE

Introduction

With a generator, you are able to convert your chemical or mechanical energy to electric energy.

Generators are used for various functions depending on the type of purpose you would want it to serve.

In this case, I am going to talk about a generator that is used to supply power in your house.

Generator running but no power in the house?

Loss of residual magnetism

Generator Problems No Power (Why)

Generators work by moving electrical conduct through a magnetic field.

Magnetism is very key in the process of power output through magnetism by allow electric power to go through so that it can release power for usage.

Residual magnetism can be lost by connecting the generator when it is not powered or letting it run for too long without connecting it to the output.

Remedy

Use the electrical drill method to pull back the chuck on the generator.

Pulling the chuck in reverse direction technically excites the generator and makes it to produce electricity.

Generator under voltage problem

What causes the generator under a voltage problem?

1. When the prime mover speed of the generator is too low.

You can adjust the prime mover speed of the generator to the specified rated values.

2. Your generator has some rectifier diodes broken by the generator itself.

You are required to regularly check and replace any broken diodes if any.

You can seek assistance from a generator repair specialized.

3. When the surface of brush contact is too small thus the contact pressure is insufficient hence poor contact.

Adjusting spring pressure is highly recommended to ensure that the contact is firm for electric current transmission.

4. Ground fault or short-circuiting error especially at the field winding or stator winding. Check the problem and fix it.

5. When the brush of the excitation electromechanically brushes is not at its neutral position.

The brush position can be adjusted to its correct position or replace it.
6. When the resistance of the excitation loop is significant.

The magnetic field resistance should be reduced thus increasing the excitation current.

Check for additional winding connections in case of semiconductor excitation generators.

RV GENERATOR RUNS BUT NO POWER

Introduction

A generator can develop a mechanical issue all over sudden for instance, for instance, you find an RV generator runs but no power.

In most cases what results to portable generators not to produce power could be due to loss of residual magnetism.

This can be easily rectified by pulling the chuck reversely technically to excite the machine, restarting the machine or checking on the circuit breaker.

Sometimes you can try all this and find that the RV generator runs but no power.

Now, in this case, you have to check and ensure that the cables that are used are firmly connected to the generator.

There could be cables that might be disconnected unknowing and reconnecting them solves your problem.

Check on the ports that the wall plugs connect to ensure that there are no loose screws or bolts.

This might make the generator be unstable and make it lose power in the circuit. This makes the RV generator run but no power.

GENERATOR TROUBLESHOOTING NO VOLTAGE

Generator with no voltage.

This means that the generator is running but there is low or no power output from the generator that you are using.

Voltage in this context is the electric potential that can be given out by a generator.

In case it goes down it can be easily noted on the points to which the power is supplied.

Generator troubleshooting no voltage?

Here are several possible means to help you solve the problem.

Start the generator and check the engine rotation speed and see if it is running normally.

Using a volt-ohm meter you can test and check the amount of power produced in volt receptacles.

If it is below the normal you can restart the generator and give it a few minutes to run.

Using your meter you can test and see if it has gone back to normal.

This will help reset the engine rotation.
If it doesn’t work visit a nearby authorized dealer from where you can have it checked.

INVERTER GENERATOR NOT PRODUCING POWER

Introduction.

An inverter generator produces a lot of alternating current electronic power on every engine rotation it makes.

The type of power produced by this inverter generator has to be converted to direct current that can now be used directly on wall outlets.

The power is at a very high voltage and therefore the microprocessors in the inverter convert it to smooth, clean, consistent and stable power that is safe for us.
Your inverter generator not producing power?

Loss of residual magnetism.

Most portable generators use magnetic energy to produce electricity.

This can be easily caused if the generator has not been in use for a long period.

To prevent this you should at least try to ensure that you engage the generator regularly.

Failure of the microprocessors in the inverter to convert the Alternating current to direct current.

This can be very dangerous to the safety of the equipment that is connected to it.

Ensure the inverter is checked by an electrician.

Generator Problem With Voltage

If you’ve been experiencing a loss of voltage with your generator for a while now, then you probably know that it’s due to a loss of residual magnetism.

The following are steps that you could follow when this happens:

1. You first have to locate your generator’s voltage regulator.

2. You will find two wires; one of which is red and the other is black or white.

3. Unplug these wires that are attached to the generator brushes.

4. You have to attach the black or white wire to the ground battery terminal of your generator.

6. The next thing to do is locate the light and begin the motor.

7. You should then attach the battery +12 Volts, which is a red cable, to the red cable you unplugged earlier in the process.

8. After this, be sure to disconnect the wires and replace the plug.

Info: This process then causes your generator to restore the residual magnetism that has been lost, which was why your generator lost voltage in the first place.

Your generator should be functioning again after this.

GENERAC GENERATOR RUNS BUT HAS NO ELECTRICAL POWER

Introduction

Generac generator is a standby generator that connects automatically in case of an outage, the generator kicks on immediately after ten seconds of a power outage.

This makes it very efficient for usage.

It runs on natural gas or liquid propane fuel and it has an engine that converts this to produce electric energy.

It turns on and goes off automatically there you do not need to be there to do that.

Your Generac generator runs but has no electrical power?

1. Check the ports where you connect your plugs and ensure that they have no particles that could be causing blockages to remove them and ensure your connectors fit firmly.

2. Check the circuit breaker and ensure it is switched on.

It could be electrical connections. Ensure that all connectors are well connected.

3. With some in case if it still doesn’t work disconnect and connect again.

After checking all the simple things and it does not still give power out.

4. Check the alternator if its faulty with the help of an expert get it changed.

Generator Output Voltage too High

Portable generators can help make power available in locations far away from the main grid.

However, there can be a challenge with low or high voltage. Generator overvoltage can result in fires and equipment failure.

Below, we look at what can make generator output voltage too high:

Causes of generator overvoltage

  • Restrictive setpoints are a common cause for generator overvoltage. Ensure to balance the loads to prevent the generator’s fast cutting IN and OUT.
  • AVR failure can also cause a generator to have voltage issues. You may need to contact a generator engineer to have this issue sorted out.
  • Your generator can be affected when lightning hits the power lines or your vicinity.

How to reduce generator voltage

A generator engineer can best correct generator overvoltage. One of the temporary ways to clear the fault is by clearing the alarm in a generator’s control panel and restarting to check if it reappears.

A generator’s output voltage increases, more so, when running machinery. This can cause equipment damage and lost time, both of which are expensive.

You can adjust your power needs in a generator by monitoring its voltage using a voltmeter.

How to Adjust Generator Voltage (step by step)

Generators produce power at rpm. It is vital to set a generator’s power output in relation to the expected load.

Below is a step by step guide on how to adjust generator voltage:

Step 1

It is vital to first consult the manufacturer’s manual before using a generator.

This holds due to differences in capacities and limitations. Failure to comprehend the two can lead to equipment damage.

Step 2

Locate the generator’s voltage dial at the side and adjust the voltage to your power requirements. Note that some generators may not have a voltage dial.

Step 3

Generators that lack a voltage dial are usually fitted with a throttle on the side.

However, some generators will have both a voltage dial and a throttle. You can adjust the generator’s voltage by:

  • Increasing the RPM to increase the voltage.
  • Decreasing the RPM to lower the voltage.

Step 4

Ascertain the amount of voltage required to run your appliances by making use of a voltmeter in the location where the former will be plugged in.

This step is useful if you are going to adjust voltage using the throttle.

However, it is always advisable to first confirm the voltage being emitted from a socket, even if your generator is fitted with a voltage dial to help avoid appliances from being blown up.

Step 5

Finally, you can plug in the appliances you wish to be powered. The above steps will ensure the safety of appliances and users besides the economy in fuel consumption, which can go a long way in ensuring you get value for money when using the generator.

Any power produced beyond the load limit is a waste of fuel and can blow up the appliances in use.

Lack of enough power production can lead to improper functioning of appliances.

Generator Not Putting out Full Power

Fixing Your Low-Power Generator

The most common cause of generators not putting out full power is the loss of residual magnetism.

Apart from residual magnetism, here are some major reasons why your generator does not produce or produces low power:

1. Capacitor and the Alternator

If the generator runs but produces low or no power at all, the first thing that should be checked is the circuit breaker.

A circuit breaker is designed to automatically and safely switch off your generator in case of a power surge.

Another part that is likely to lead to the loss of full power to your generator is the capacitor.

It regulates and induces the voltage to the rotor. Other than the capacitor, the alternator is another component that is likely to be the cause of low voltage to your generator.

This is most common if it has not been in use for a long time.

2. Stator and Automatic Volt Regulator

The rotor is made to rotate in the fixed stator windings that produce electricity.

A test can be done on your generator to determine if there is an open circuit that would indicate damage to your generator.

On the same note, an AVR (automatic voltage regulator) is responsible for balancing the amount of voltage that your generator outputs.

With an adjustment screw, this can be tuned to produce the desired amount of power that you need.

Summarily, several reasons are likely to lead a generator not to put out full power.

It is important to consider checking with an expert technician if the problem is not solved by yourself at home.
