On the road generator problem. Help?

We're traveling and the generator will not put consistent power to our 2010 Itasca Sunstar 32k, the generator is an Onan 5000 gas. The generator starts fine and runs fines, no stuttering. The power in the coach cycles on and off every second constantly. The generators oil is fine and all battery connections look fine.

Any thoughts?

    Ken, I would make sure that both roof air conditioners are off if you have two, and then see if the power is still cycling. Also what make and model is your generator? I am a guessing that it may be an onan marquis, being a 5kw. It almost sounds like there A thermo breaker that is resetting rapidly, or possibly the change over relay is dropping out, in the auto transfer switch, possibly due to high current draw. Geo


    The roof air units were off. The microwave was on but not running, and the fridge, that's it. There was very little draw on the gen. It is a onan marguies model HGJAA.
