1993 vintage MDL4 model. Main problem was the "on/off" red rocker would trip the instant I positioned the black rocker in either preheat or start modes. I finally traced the problem to a short in the start relay solenoid. (part 307-1031)
Replaced that, and now preheat and starter work but the gauges are not working and the injection pump solenoid is not getting 12 volts to open. Have checked wire connections carefully so now all I can figure is something on the engine monitor PCB board has gone bad.
Replacement not all that expensive at $160 or so, but will be a major PITA to remove and transfer the wires to a new board.....so before I do that, any other ideas of what to check ?
DC breaker and sensor overload breaker have continuity, so not one of those. The engine temp gauge doesn't work but the generator ran fine before with it not working before these problems occurred so unlikely to be that....but I wonder.
