Our western unimount will only go to the right!

    Please Help!
    We have a 86 chevy silverado with a western unimount with a 9 pin hook up. It's all hooked up with new diodes, a new sylenoid, and new coils on the plow. The problem is no matter what direction we hit the controler, the plow only moves to the right!! Does anyone have any suggestions? Our brain is fried like KFC after this one!

    Thanks a bunch,
    Plowin' Bucks

    Check the wiring on the solenoids compared to western's schematic. Also be sure that your connectors are clean.

    Thanks, We did wire bush the heck out of everything, including contacs on ground and terminals. We have a wiring schematic we got from western, and I'm pretty sure we have it hooked up right. People from the dealer tell us differnt things about grounding the soleniod. we have tired it both ways and it does the exact same thing.

    Does that have something to do with the fulid in the plow?

    Under what functions does it tilt to the right?

    Up? Down? Left? Right?

    This is not a fluid problem.

    Oh I'm sorry, no matter what direction the controler you push, it tilts right.

    Is the setup brand new on the truck-or had it worked in years past? Very strange that it tilts right even when you hit down.....

    Any chance you could try a different controller?

    sounds like the s-3 is stuck shifted. pull the valve and push in the end of it with a screwdriver. it should move about 1/8 inch.

    If the valve was stuck-why would that cause the motor to run even when hitting down?

    Ok so I went ahead and pulled out all three of the vaules drained everything and cleaned it all. All but one pushed in with little force. The bottom(longest) one did not push. Cleaned it up a little and it still does the same thing. I am thinking to just go ahead and get a new one. Should I get all three while I am at it?

    And also we took the motor off, the filter is fine, but the shaft on the pump assembly will only turn freely in one direction. Is it suppose to spin freely in both or at all?

    Does the motor run when you hit down?

    (I was assuming before the answer is yes, but maybe that was a bad assumption)

    I would try changing your S3 coil with another coil. They should all be interchangeable.

    Do you have a test light or voltmeter - so that you could check to see if you are getting power at the coil when you engage functions?

    yes, I checked and we are getting power to the coils. The coils magnitise as well. I've cleaned or replaced the valves and all the parts in the hydralic block. We have good power at the motor and it seems like it has good pressure. The lifter doesn't move nor does the angling arms.

    Well I don't know. The hand control is brand spankin' new western one and I paid a lot more than 35 bucks for it!

    If you are getting power where you need-and the coils are magnetizing correctly when you hit the functions, then your problem isn't wiring, the coils, or the controller.

    Your best bet is to take all the valves out, flush everything with kerosene or diesel fuel, and refill. Clean it multiple times, and I would flush your angling rams as well. Something is causing your brand new valve to stick.
