New Onan 5500 Generator
I recently purchased a 2013 Challenger 37DT with a Onan 5500 generator. The generator starts and runs fine, but will not power anything. The green light ( and red light on the outside start switch) blink rapidly once started, and never stop. All fuses OK and breakers on inside and outside are good. Fuel good, oil good, only had 12 hours so far. Anything I am missing? I see the posts about the fault codes, and my shows a code 12, but can't find any details.
