    tk md200 runs fine on electric but wont start on diesel, code 35



    when I start up the controller on diesel it comes on, doesn't buzz or prime, no fuel pump engage, just flashes code 35. I checked all the fuses and they are fine, I tried a new fuel solenoid and now I was advised to swap out the MP.

    just wondering if the problem is in the MP or maybe something less expensive that I missed.

    Check all connections at battery and the main fuse which is normally at the battery.

    The connections/voltage at the battery are all good. Just wondering if there's anything I could check before swapping out a board for $900.

    I was double checking the fuses/voltages at the board and managed to start it on diesel. It ran for 10 mins and shut down to code 63/84. Waited a few mins and cleared codes, started up and ran 10 minutes before shutting down to code 35.

    Not familiar with a remote switch, do you mean the box door sensor?

    It's a switch fitted to the unit frame it's purpose is so you can stop the unit without climbing off the cab roof it's normally fitted on the right hand side as you look at the unit from the front.

    Oh, the guy who trained me always called that the master switch lol.

    I pulled a MP out of another unit to test against this one and the unit started right up on diesel.
    The bad board would not show voltage to the fuel solenoid wire on the board, I think the diesel circuit was just worn.

    Thanks for the help.
