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
From your post it sounds like the engine is not cranking. Will it crank if your push the combiner button on the dash? Clean all battery connections first. Does it turn over? If you have a clamp-on amp meter check to see if amps are getting to the starter. If you don't have an ammeter back your tow car and connect jumper cables directly to the genset. Will it turn over now?
