Generator runs fine, but no electricity in coach

We were parked at a casino overnight. Generator and electricity worked fine in the evening. Next morning, electricity stopped midstream as the coffee was filling the cup. But generator was still running. Shore power works, as our next several days were in RV parks.

No circuit breakers appeared to have flipped off, but after this happened, I purposely flipped them all off and then on again....on the generator and every breaker inside the coach. Aux batteries are good. One had a slightly loose negative cable. Tightened that, but still didn't fix the problem.

This coach has an automatic transfer switch box in the electric storage bay. Didn't see anything loose in there. Nothing felt hot.

Any ideas?

    Yes, turn OFF and back ON the breakers on the generator itself.

    Generator was running but did you verify it was actually putting out power? Some generators have an overload reset pushbutton that must be pushed in addition to breakers.

    Also a good idea to check, clean and tighten DC and AC connections. RVs vibrate and bounce down the road and connections become loose. Unplug, solar off, gen off, batteries disconnected. Again safety as a battery short can get very hot in an instant.

    CBs can be deceptive - push them fully off then on. Check inverter CBs also as some pass through 120V.

    Next I would unplug shore power and measure AC in and out of transfer switch with the gen running to isolate the problem. BUT don't do this unless you fully understand the danger involved and related safety.
