Does anyone out there have or know where I can find a wiring diagram for a Super 99GM tractor? My buddies has electrical problems (it won&#039;t charge). We took the generator to an electric shop. It tested OK but the regulator is bad. By the manual it should be positive ground, but it doesn&#039;t appear to be hooked up that way (probably what killed the regulator). Anyway, the wiring is in poor shape so we&#039;d like to start over but need a diagram. Thanks!
