I have a 1994 Telsta bucket truck. It would start from the bucket and when I would release the starter button it would stop running. After several attempts it kept running. When I turned it off the generator starter motor kept running. The only way I could stop it was by disconnecting the wire to the starter motor. The generator is a Onan 1994, 4500 watt single phase 240 volt propane with the pump mounted with an extended shaft. I can't find a model /serial number tag. It is probably hidden under the cover, the manual from the truck description states Onan 4.5 BGD generator. Also when attempting to start it it would klick and not turn over. I would think the solenoid is bad. Thank you in advance Bill
