Onan QD 10000

1 control board on those and it may have a small transformer that is part of the voltage control circuitry. The control board is located in a holder mounted on the barrel. To the left looking in the service door. A molded plastic area and the board is in a metal tray. 3 screws and one connector. That board does everything and it’s a $700 item. There are sensing wires on the output breaker and also the transformer I mentioned on some models. High voltage is not a common issue on those. I would be checking every wire connection. I have the luxury of having “test boards” to just plug in. I save old ones with other issues that I replaced. If you give me the exact model info of the ID label I can look up the machine and it’s wiring to see what’s in it. Model info is on labels in two places usually.
