    Hi guys I am new at this so be kind. I mounted a v plow, relay controled to my 1995 gm 3500hd. all the lights work as they should but the plow its self will only retract the right side of the blade. can you guys give me some guidance as to where to start?


    Thanks !!

    Right wing retract is the default function when the motor runs but no valves are shifted so mostly likely so all your valves are dead. When you lose them all it's usually caused by the small red 12V wire that's connected to all the valve coils. So start with checking the small red at the valve coils. It should show battery voltage with the ignition on. If it doesn't then it's either broken in the harness or has a broken pin in the grill connector plug (it's in the battery harness plug). Only other cause is a defective controller but it's more than likely the red wire.

    Thanks for the reply I did find the small red wire to the plow was chafed thru and spliced it.
    BUT now the controller will not turn on!! It lights up but wont turn on checked the fuse under the dash its OK so what am I missing:confused:

    If it illuminates but won't power up then the controller is most likely faulty. Pretty common on those units. Borrow a control and retest if you can.

    Ok I found 1 of the small fuses in the controler was blown so (I know like a fool ) I bypassed the fuse with a hard wire. the result is that the on button on the controller is on all the time and the pump motor runs nonstop.
    Could the new relay be faulty? How can I test it.
    thanks again

    Does it stop if you disconnect the controller? If so then the controller is still causing problems.

    could I have fried the controler?

    Very possibly yes, doesn't take much to kill one. Try the test and let us know but I'll say the controller is the issue.
