My 91 coach has THE KOHLER MODEL 12.500067-RV SPEC 135014 with the Yanmar MODEL 4TN82E-RK engine. It will not start inside the coach if you go outside and hold forward the black rubber boot solenoid you can start it with the switch outside and it runs fine but puts out no power and the fan isn't running any ideas??? I am in Sacramento have spoken to a couple generator repair shops and I am having problems getting someone to work on it One tech said it could be the control board . Does anyone have a wiring diagram or parts list for this generator?
Thanks Bob
