Hello, New to the Forum looking for some guidance. Have a Generac 6500 that produces power in the 12v battery charge outlet, and Makes AC in the round 4 prong 120/240 outlet only. I replaced the Regulator, but that's as far as I got. I was thinking of replacing the control board, but it's pricey. I'm good with a wrench, but slow in the electrical dept. Any Input appreciated.
Looking at the wiring diagram (link below), if those circuit breakers are good and you have 240 volts at the L14-30 outlet, you should have 120V at the other outlets as well. Also verify that the GFI circuit is not tripped.
