    Onan gen issue-gctid800821

    The Gen start, generate 123 ac but runs only if i hold the elm start switch in the start position. i really need a wiring diagram from the lower Elm to the generator for properly diagnostic.

    Good oil pressure, new fuel and oil filters

    Any help is appreciated. thanks

    Not familiar with your model, but there probably is an oil pressure shutdown switch in the run circuit. Check it and its connectors.

    Last spring my westerbeke did the same thing, just needed to clean and, tighten and resecure the oil shutdown switch connections.

      You my have the same problem I have with my onan. Turn on the microwave or something else to put a load on the generator. Mine will start when I do this. Once it starts I turn the microwave off. Also I always tell folks if they have a older genset like mine there was a recall on the exhaust. they will fix it free of charge. It has killed a few folks in their sleep.

          sorry Pete,

          We took off on a 5.5 hour drive to Buenos Aires before I saw your question. I wont be home until saturday and then I can answer your question. Now ya got me thinking. It might have been a kohler generator on a1990 F32 I owned....... not to many brain cells left right now. :blink:
