I would start looking at the solenoid on the starter. It could be stuck in the engaged position due to dirt or welded contacts. It is easy enough to take off and inspect.

Heard some additional racket (other than normal) going on in the area of the Onan compartment. Sounded very similar to a cooling fan banging around a fan housing. I then tried to shut it down remotely but when it almost was dead and I released the button from the off position, it would start right back up. Ran outside and hit the off button on the Onan itself and the same thing happened. Pulled the spark plug leads and the Onan shut down but it continued to try and start back up. Disconnected the 12 pin plug with no effect. I summarized that the Onan starter had been possessed or something. I ended up disconnecting the rear battery and things finally went quiet. That cable was HOT!
