Generator in ERO mode.

I have a Cummins Onan Generator RV QG 5500, in a Thor Hurricane 29M. My generator is in ERO Mode, that's Engine run only mode. It's because of low battery's. Anyone know how to reset it to standard output. The switch light will flash continuisly after the generator starts. Thanks in advance.

never heard of such, but plenty of us have had our generator running but not providing power, since it's own BREAKER(S), on the generator itself, had tripped.

Low batteries would keep it from starting for sure but shouldnt keep it from producing power,check all of your breakers including the one on the generator.

If everything works ok on shore power but not generator then it might be in the transfer switch,or a issue with the generator head itself
