6 comments on “How To Diagnose A Generator That Has No Power Output.

  1. Thanks for the info. I have to check my Briggs & Stratton 5500 watt generator. I can start the engine with the breaker set on 220. But will not produce any power. And if I start the generator with the breaker on 110 and try to set it on 220. It will kick it back to 110. Either way, there is no power. If you have any suggestions please let me know your thoughts. I purchased the generator in 2008.It is a Storm Responder; Thanks Thomas!

    • Hello, Your welcome hopefully it helps. If the generator has been stored for awhile and not used it might have lost it’s resista magnetism. The video above is also the way to restore the resista magnetism. So you might want to test it/ restore the resista magnetism like in the video and then hook all the wires back up and try it and see if there is power output. Might save you from having to buy the AVR. A generator should be started and loaded at least every 3 months to ensure proper operation by keeping the brushes clean and to make sure it doesn’t loose the resista magnetism. I have heard both good and bad stories about the storm responder generators. Change/Check the oil regularly as i am pretty sure they don’t have the low engine oil shut off and keep it level when it’s running. Good Luck.

  2. Appreciating the dedication you put into your site and
    detailed information you offer. It’s good to come
    across a blog every once in a while that isn’t the same out of
    date rehashed information. Wonderful read! I’ve saved your site and
    I’m adding your RSS feeds to my Google account.

  3. Great site! Thank you so much for your information.

    Don’t wish to give the impression of disparaging the work you have done putting this site together.

    However, if generator starts and runs fine, but not showing a voltage, and has been sitting a while, let it run for about 10 minutes, turn off and start again.

    Voltage may show on second attempt, as my Duromax 10, 000 did.

    Just thought I would pass on.

    • It could have lost its residual magnetism. So you can plug a drill with a cord into one of the 110 volt plugs then squeeze the trigger/ power button and turn the drill chuck by hand 4-5 times to restore the residual magnetism. You could also have a bad AVR which is not stepping up the power.
