I had a friend take it for the weekend, so I sent him with my little Honda generator.

He called me a few hours later and said everything came back on. He tried starting the generator again and lost power again and a few hours later everything came back on.

Could it possibly have something to do with the auto gen start system?

Thank you for any help.

If things work on shore power but not on the generator there only are a couple of likely problem areas. First check that the generator is actually putting out the expected power. Check with a volt meter at the generator. There is a circuit breaker in the side of the generator that needs to be in the proper position. The second, and more likely source of your problem is the automatic transfer switch. It is where the shore power and generator power come together and it is the device that switches (prioritizes) generator power over shore power. Does running the generator “shut off” the shore power(it should) or are you trying the two systems separately? I’d pop the cover off the ATS and check the security of the connections.
