Generators are a great backup for when the power goes out, but what do you do when your generator doesn’t turn on? Here, we will show you how to troubleshoot your generator and get it up and running. Stay tuned for more tips from our blog!

Why Would A Generator Run But Not Produce Electricity?
A generator needs two things to produce electricity – fuel and a spark. Generator will not produce any power if either of these is missing. The most common cause of a generator producing no power is the loss of residual magnetism in the alternator.
This can be caused by several things, such as a loose connection, a problem with the brushes, or a faulty voltage regulator. Another possible cause is a failed AVR or another excitation component. The AVR likely needs replacement if the voltage is around 50-70V on each phase. In any case, it is best to consult a qualified technician to diagnose and fix the problem.
How Do You Fix A Generator That Runs But No Power?
If your generator is running but not producing power, there are a few different things you can try to fix the issue. First, ensure the generator is properly plugged in, and the breaker or switch is turned on. Then, start the motor.
If the generator isn’t producing power, you can try connecting the battery +12 volts (red cable) to the red wire on the terminals for three seconds. If this doesn’t work, you may need to remove your wires and replace the plug. With any luck, this will get your generator up and running again.
Is There A Reset Button On A Onan Generator?
If your Onan generator isn’t working properly, you may be wondering if there is a reset button that you can press to get it back up and running. The good news is that there is a simple fix that you can try at home. Hold the Stop/Prime button for a few seconds to reset your Onan generator.
If the generator doesn’t start up immediately, repeat the process. Once the generator is running, turn on any breakers that may have been tripped. With a little patience, you should be able to get your Onan generator back up and running like new.
How Do You Test A Voltage Regulator On An Onan Generator?
Onan generators have a voltage regulator that controls the amount of voltage reaching the motor. You can test the voltage regulator by measuring the voltage on pin 7 with a voltmeter. The instrument should display 12 volts. You can also attach the voltmeter to the motor’s brushes.
The voltmeter should reflect 10 to 11 volts across the brushes. If the voltage regulator is not working properly, it may need to be replaced. However, you should first consult your Onan dealer or an experienced technician to diagnose the problem. Replacing the voltage regulator is a complex process that should only be attempted by a qualified professional.
Why Is My Generator Running But Not Putting Out Any Power?
Have you ever used your generator after a long period only to find that it won’t generate any power? Or, have you ever been using your generator only to have it suddenly lose power? If so, then you’re not alone. It’s a problem that is quite common and has a relatively easy fix. The issue typically has to do with the loss of residual magnetism.
Residual magnetism allows generators to keep producing power even when turned off. However, that magnetism can slowly diminish over time – especially if the generator isn’t used regularly.
Additionally, leaving a load connected to the generator when you shut it off can also cause the residual magnetism to dissipate. Additionally, running the generator for too long without any load can also lead to a loss of residual magnetism. Finally, if your generator is new, the long-distance transportation vibration may have caused the residual magnetism to diminish.
Fortunately, there are ways to help prevent this from happening or – if it does happen – ways to fix it. For example, suppose you know you won’t be using your generator for an extended period. In that case, it’s important to disconnect any loads and run the generator until it runs out of fuel.
This will help keep the residual magnetism strong. Additionally, if you find yourself in a situation where your generator has lost power, you can take steps to try and resurrect it. For example, you can try disconnecting all loads and then cranking the engine for 30 seconds without starting. This can sometimes help to reestablish the residual magnetism. If not, you may need to consult a professional for further assistance.
Do Onan Generators Have Alternators?
When your Onan generator isn’t starting, one of the first things you’ll want to check is the circuit breaker. Onan generators are equipped with a manual reset circuit breaker that trips if there is an overcurrent condition. The circuit breaker is located on the control panel of the generator.
To reset the circuit breaker, push the button in. You may need to replace the circuit breaker if the generator doesn’t start. Replacing the circuit breaker is a relatively simple task that can be completed in minutes. With a few tools and a new circuit breaker, you can have your Onan generator up and running again in no time.
Where Is Circuit Breaker On Onan Generator?
Most Onan generators will have the breaker switch located on the lower right-hand side of the opening. This can be not easy to see from underneath the motorhome, so it is important to know where it is before operating the generator.
The breaker switch is responsible for turning the generator on and off and is also a safety feature that prevents the generator from overheating. If the generator does overheat, the breaker switch will automatically shut it off. Knowing where the breaker switch is located and how to operate it can be valuable if you ever need to use your Onan generator.
Final Verdict
If your generator doesn’t turn on, there may be an issue with the fuel system. To determine if this is the case, check the fuel gauge to ensure you have enough fuel in the tank and try priming the pump by manually pumping a few times. If you’re still not getting power from your generator, it might be time for some repairs. Contact a technician to help get your generator up and running again.
