Does anything on a/c work on the generator. There is a breaker on it as well, it is located, on the generator, under the cover plate. Looks light a black light switch.
Found the breaker panel. On a DS27 it is in the bedroom under the vanity table aft drivers side. Found the circuit breaker on the Onan generator(below the start switch right side). Played with it all to find that it probably is the changeover switch on the Onan. Heading to the dealer today will update when it is fixed
