Onan gas generator not stating. Chassis engine running. Batteries charged. Press start button - sounds like rapid fire gun. How do I add video here?? thanks Don
Check all your connections between the battery and the generator, both grounds and positive wires. While a bad starter can certainly cause the clicking you're hearing, a poor connection and the consequent votlage drop at the generator when cranking can do the same thing. A bad starter solenoid in the generator, if it's separate from the starter motor as I think most are, could also be another cause.
