I have a 86 pace arrow. When I turn the key, I only get a click noise from the starter solenoid. There are two wires coming off one side of the solenoid and one is getting hot to the touch. I believe this wire leads to the fuse box. When I disconected this wire from the solenoid, the RV turns over but still no start. I can tell the wire is getting a heavy load because it kicks when I turn the key over. I replaced the solenoid with a new one. Any ideas?
