GeneratorAC weird problem... stumped

Yes the inverter Onan part #327-1461 (about $950) is a large silver box that is connected to the generator by fairly large copper wires. The box usually has fins on it for cooling. It will also have large wires coming back out of it that connect to the output load connection. It can be replaced separately from the generator components. Onan will only sell the inverter module with the generator control box so you will need to replace both. It is possible that you have a bad capacitor on the inverter module thus causing the inability to start your AC units but you can still run resistive loads. You may need wiring diagram 611-1236 to R&R the inverter / control boards.
