Cummins Onan RV QG400 Model 4KY - 26100R on 2017 Thor Chateau 29G. I once saw an online explanation for using the "switch" thing on the generator. The one with the light codes.
I can't find it any more. I have learned how to reset the generator "breaker" switch, but don't know about the nearby "other" switch.
I wish I knew the names of these things.
