I could use some generator advice. I have a Onan in my class A and when I start it up as soon as it starts to send power to the unit it shuts itself down. So basically as soon as the transfer switch ...
The code if I am reading it correctly is Blink Pause Blink Blink, so a 12? I have a Onan HGJAB 5.5 Kw. Code 12 is listed as an overvoltage fault. (controller unable to maintain rated voltage) Corrective Action: See an Authorized Onan DEaler. I am confused why this does not happen sooner. I can load the heck out of it and get nothing until 1/2 hour into running the unit. My only thought is that the battery charger kicks in after a bit and that is a heavy load?
