    Try starting it with all electric items turned off. Water heater, Refrig, Inverters and converters, A/C, TVs, etc and letting it warm up an come up to speed before turning everything back on. Mine does not like the converter to be on line when it first starts but after 5 minutes or so it works fine. Good Luck.

    Are you driving and is it hot - overheating?

    Which flash codes is it providing?

    Is the MH's fuel tank above 1/4 tank?

    Is the oil level on the Onan full?

    I really question the quality anymore of the Cummins/Onan gen sets. I've had to take mine in several time. On my 29.2 it had a catastrophic failure, turbine shaft completely broke. next time the board fried. 6 weeks wait time tells you how busy they are fixing units. Wish there was another brand. I have a home gen set made by generac and it's bullet proof.
