onan Micro Quiet Generator

At the begin of the season. The Generator worked normally . About a month into the season we started having some issues. The Generator would be running than out of no where we would loose power in the coach but the generator would still be running. I could here in the back by the panel what sounded like a clock ticking. Almost like something was trying to reset? If I shut the generator off and restart it would come back and last for who knows how long. Some times 10 minutes other times weeks. Than about August we had the ac ON watching a movie when the Generator Quit running and would not restart unless the breaker was off. The other thing I can add it that if I plug another generator into the Shore line I have power and it never shuts off. The only problem I have with this is that the AC wont come on. The generator has plenty of power to operate the AC unit but nothing happens. Any Ideas. I am at a total loss.

I wonder if the "clock ticking" and the power loss could be a problem with an automatic transfer switch. An ATS might be connecting on/off with a bad connection and make the clock ticking sound. The AC problem seems like it might be unrelated, unless you have a 50A service and the AC is on the second half - in which case a bad ATS might have affected only that one AC unit.

Do you have an ATS? It sounds to me more and more like that's it. When the gen powers up, it tries to throw the ATS and shorts out. When you run a gen or shore power through the shore power connection, the ATS isn't shorting - the problem is on the gen side of the ATS. With the gen breaker off, the ATS never switches and you do'nt have a problem.

Well, that's my best guess for the symptoms you have. I'd open up the ATS, or bypass it to test.
