    I have been working on this plow sence last snow storm what happen was there was a small crack on the solenoid and im guessing snow got up in it and shorted out the system.

    i bought this truck with the plow on it and i no i should of checked it before but i dident :gunsfiring: :eek: ...


    but when it shorted out it melted all the wires in the TRUCK side harness about a foot from each plug. ( controller plug and plow plug)

    i put a new western solenoid on it and also fix the wiring harness but now im not getting power from the one wire that comes off the controler (that tells the solenoid to open).

    if i hook up power from the battery to the solenoid you can here it click on and if i hit the joy stick all it will do is shack for about a sec and quite. ( plow will shake)



    if anyone could help me out i would be very thankful...


    have a blessed day.

    Time to dig into the schematics and verify things one wire at a time. There are several possible schematics for your plow. You need to determin if you have the two or three plug system. I suspect you have relay light controls being a uni-mount so that narrows it down a bit. There is no magical solution that will fix your problem. Just systematic trobleshooting. Here is a link to the electrical schematics guide. Just identify you plow electrical system and print off those pages. This book has pretty much every electrical system they ever made. http://library.westernplows.com/ddcommon/dd_pdf/pdfs/22373.07_110108_for_web.pdf

    what i have found out is that the brown/red wire coming from the controller to the solenoid it not getting power.. does that mean that the controller is bad???

    The brown / red wire at the main relay is only hot when you press up, left or right. It's not active otherwise. Put a test light on that terminal of the relay and get someone to press controller buttons. If the light comes on then the controller is fine but if it does not then it sounds like the controller is bad, yes.
