    OK. I didn't think you were thinking Kubota diesel.

    Thinking kohler, and takes away power to the solinoid via the oil pressure snensor

    Check the Throttle Control Relay CR2 for stuck normally open-to-common contacts. CR2 supplies power directly from the battery (+) to the throttle (speed) and fuel (run/stop) "pull" coil windings with the ignition switch in START position.

    These pull coils are high current momentary windings and continuous power to them will burn them up. Miller upgraded CR2 from a 30A rating to 70A. Based on the SN you listed, yours should be the 70A version.


    Have you checked both solenoid adjustments and linkages per the unit manual instructions?

    Well if the fuel shut down solinoid is disconnected, that would shut down the fuel. if it doesn't then the shaft that the coil operates is obviously stuck

    Turning off the switch shuts down power to the ignition coil, and applies power to the shut down solinoid

    Sounds like one that needs Cruizer.
