    Picked up a 88 wrangler with a westen hydraulic uni mount on it. Prevous owner was a hack and everything on the jeep is cobbled. Started to work on the plow. So far I have taken off the pump motor and drained the atf cleaned out the filter added new atf, Installed a new motor relay. I have sanded the electrical connections at the power and ground to the plow motor, battery, and fire wall ground
    So i plugged the harness and when I try to operate the plow with the controller the motor starts and will not stop unless i unplug the pin harness.
    Per the troubleshooting guide I unhooked the IIIa wire from the motor relay, when I try the controller with it unhooked I get a click from what I'm assuming is the solenoid activating as it should.
    I have run out of troubleshooting guide ideas, if anyone has any ideas for me to check I would appreciate it. Truthfully if I could just get it to raise I would be happy.
    Thanks Mike

    I believe that the solenoid that controls the motor pump is activated by grounding the small pin through the controller, opposite of a starter wiring.So the other small pin is joined to the hot stud on the solenoid,is that how yours is wired? if so the solenoid may be badly worn and when it is activated it is welding itself across the studs and not releasing right away (common problem). at this point a hammer is handy :gunsfiring: lightly that is.
    Otherwise the controller itself is to blame
    if their is no jumper wire on the solenoid then the cab control sends a hot to the solenoid to activate, either way the result is the same with a bad solenoid.

    ok,,lets start here...you stated you got a new solenoid correct???
    what kinda did you get a plow solenoid or auto???
    the solenoid is activated by a pos. signal off the controller not a gnd signal.
    the motor running is b/c of a couple of things.
    the wrong solenoid,,bad solenoid,,,improper wiring,,,bad controller.
    take the pos to the plow (big wire) off the solenoid. test light to both little pins, one should be gnd, one should be nothing or gnd. then raise or left right the controller and see what happens.

    your post said firewall ground. is the plow negative hooked to the battery or the firewall? it must be to the battery. dimming lights and slow plow reaction are usually from low voltage. a loose battery cable will cause this every time. i have seen this hundreds of times my 16 years as a plow tech.

    make sure all of your connections are bullet proof. battery, solenoid, ground to the motor, and frame. any loose connection will fail. trust me.

    if you have a new western brand solenoid you cant wire it wrong. look for the word trombetta on the solenoid.

    good luck.:salute:
