Now let’s discuss these fixes in detail.
Loss of Residual Magnetism
Fortunately, there are two methods of restoring residual magnetism to the generator and getting it back up and running – the 12 Volt Generator Battery Method or the Electric Drill Method. In this article, we’ll look at these methods in detail so you can quickly get your generator back to functioning properly.
12 Volt Generator Battery Method
To fix a generator not producing power, you’ll need to use the volt generator battery method: unplug the two wires connecting to the generator brushes, connect one of those to the ground battery terminal, and plug in a light. Here’s what this step-by-step process looks like:
|Unplug two wires
|Unplug the two wires that connect to the generator brushes. One is red and the other is black or white.
|Connect one wire to ground terminal
|Connect the black or white wire to your generator ground battery terminal.
|Plug in a light & turn on switch/breaker
|Plug in a light and turn on your generator breaker or switch and start the motor.
|Connect battery +12 volts (red cable) for 3 secs
|Connect your battery +12 volts (red cable) to the red wire on removed terminals for three seconds.
|Replace plug & finish up
|Remove your wires and replace the plug; your generator should now be producing power again!
Once you’ve completed these steps using the volt generator battery method, you’re ready to move onto fixing it with an electric drill.
Electric Drill Method
Plugging in an electric drill to the generator receptacle and switching the direction to forward can help excite the field, allowing the generator to produce electricity. To do this, depress the trigger on the drill while spinning it in reverse.
This process will kick start a generator that is not producing power. Once finished, releasing the trigger and turning off the generator will ensure everything is running properly. With this method, you can easily fix a generator not producing power without having to replace any parts or hire a professional.

Frequently Asked Questions
What type of generator do I need for my home?
You’ll need to determine what size generator is best for your home. Consider the amount of power you need, as well as other factors like noise level and fuel type. You can use this information to help you decide which type of generator will work best for you.
What should I do if my generator is producing too much power?
If your generator is producing too much power, turn it off and disconnect from the grid. If that doesn’t work, check your connections and adjust the voltage regulator accordingly.
How long does it take to repair a generator?
It depends on the complexity of the repair. Generally, it can take anywhere from a few hours to several days. Check with your local repair shop for an estimate.
What safety precautions should I take when working with a generator?
When working with a generator, take appropriate safety precautions. Wear protective gear, ensure the area is well-ventilated and avoid contact with live wires. Be sure to disconnect the power before servicing or making repairs.
What type of maintenance do I need to do on my generator?
You need to perform regular maintenance on your generator to keep it running properly. Check the fuel levels, air filter, and spark plugs regularly and replace them if needed. Make sure all connections are tight and inspect for signs of damage or wear.
Why is my generator running but no power output?
The generator may not produce power due to the loss of residual magnetism. This can happen if the generator has been unused for a while, had a connected load when turned off, ran without a load for an extended period, or experienced vibration during long-distance transportation. To restore magnetism, it’s recommended to “flash” the excitation coil by applying an appropriate DC voltage across the field terminals.
How would you get a generator to work when it has lost its residual magnetism?
To restore a generator’s lost residual magnetism, the recommended method is to “flash” the excitation coil. This involves applying an appropriate DC voltage across the field terminals to pass a DC current through the field coils in the correct polarity. This process helps the core retain enough residual magnetism to start generating power independently.
Why is my power out generator not working?
If the generator is not producing power during an outage, it’s essential to check the main line breaker. Ensure it is in the ON position, as a turned-off breaker prevents power transfer from the generator to the home. Additionally, verify the functionality of the generator’s control board. If the control board is not working, it could be due to battery failure or loose/defective cables.
