    I once had a Westerbeke that wouldn't run without the bypass (preheat) switch held down, it was a bad wire going from I think the starter solenoid to a safety sensor.

    Page 57 of the manual that is linked above has a troubleshooting guide that gives you a few options.
    IF this is the correct manual for your genny, that is.

    The guide above states the same thing Skip mentioned and Dennismc mentioned.
    There is a reference to the K1 relay
    A reference to the LOP, HWT and HET limits and how to properly check them and the psi's and temps at which they operate. You may be testing them when the genny is not running and think you have a good safety limit but in fact the limit may not open or close at the correct psi and not work.

    Did you ever find a correct manual ?

    That makes sense and will trace the wire down. One end of the separated wire goes into a wiring harness that goes into the control box. Not sure where the other end goes. It goes into the cover on the right side of the engine where the belt and coil are I believe. Lot to take off to get into there but will have to check it out as can't seem to find the issue. I also think it would be a good idea to check the relays as CSkipR suggested, not sure how to jumper them but will take a look at it.

    Tanks to all will keep on trying.

    Late to the party.

    Is this the gas, real flat head Kohler genset. Correct model 6.5R?
    Fires by a gear driven magneto with a distributor cap?
