    I have a 9 year old 7'6 Ultramount straight blade with the pushbutton handheld controller.

    For the plow to move, I have to continue to click the handheld button (whatever direction). Puch the button, the plow moves a few inches, release the button. Puch the button again, it moves a few inches.......You get the idea I hope. And it seems to move jerky when it does move (maybe thats due to it only moving a few inches at a time.

    I've replaced the solenoid. You can hear it run.
    Changed the fluid.
    Pulled pump - screens and filter look good.
    New wiring harness up to where it connects to the handheld (had a couple of suspect wires at one of my 3 plug connections.
    Bled system.

    Any thoughts? Thanks!

    The control is bad go to western and get a new motherboard there like 50-60 bucks I think instead of buying a new control.

    I assume you mean the Isolation Module? I have mine disconnected, sitting here in front of me. It says on the outside of it that it contains no serviceable parts.
    Its a 4-plug module made by Douglas Dynamics. Part # 27781.

    Is there a way to test this thing while disconnected?

    The board hes talking about is in the hand held controller, it sounds like the contacts in your controller are worn out and should be replaced

    Yea I'm talking about the handheld pull the two screws out and replace the motherbord western sells them but put rubber gloves on you can't touch it with bare hands the grease on your hands will make it not work but it tells you that in the instructions.

    Thanks for the help! My dealer let me try a different controller and I still have the same issue.

    I'm leaning towards the pump. Thoughts on that?

    You'd be talking about the same thing. They went up about $100 just last year. check back in your records, it should be part # 56472, and it was probably more like $160-$175 three years ago.

    Have you checked your plow connections? I had that happen to me a couple of weeks ago. The connection had come loose just enough to make one headlight go out and a couple of buttons were not working all the time.

    Check the grill connection. Make sure they are clean and making full contact. Also check the harness for any broken wires. Have someone push a button on the controller while you move the grill connector around. If the plow start to act normal, you know your problem is at the grill connector. Also make sure the grounds are clean and tight.
