    Control power
    light is ON, but
    snowplow does
    not respond.

    Harnesses connected to Isolation
    Module incorrectly.
    • Using the electrical schematic in this guide, verify that Isolation Module and harnesses are properly connected.

    Blown fuse or Damaged Plow Module
    • Replace all blown fuses on truck and snowplow.
    • If fuses are all okay, check for 12V at all coils and primary terminal of motor relay. If 12V is missing from any coil or relay, replace Plow Module. If 12V is present, go to next Possible Cause.

    Damaged harness(es) or cable(s)
    • Perform a Solenoid Coil Activation Test (SCAT) according to the instructions in this guide. Replace/repair any damaged harnesses and cables.

    Damaged control or Plow Module
    • Install a properly working control. If problem is corrected, replace PC board and/or coiled cord in damaged control.
    • If problem is not corrected with properly working control, replace Plow Module.

    I agree with crash of course. I am leaning towards the harness that runs your lights and controller is failing. You maybe able to check that by simply grabbing the wires where they go into the base of the plug and give them a wiggle and see if your lights cut out or the controller has no power. I just had that problem.

    I had a similar problem, the power light would come on when power button was pressed but when I attempted to lift, angle left, or angle right I would hear the solenoid click then the power light would shut off and the plow of coarse didn't operate. Come to find out one of the terminals on the soleniod were loose the slightest bit allowing the wire to move about an eighth on an inch causing this to happen.

    Definately start by checking all of your connections (including the plow also). If you can find someone with another controller, try plugging that in and see if it has the same problem. Its going to be a process of elimination to find the problem so get the mechanics guide and a test light. The mechanics guide will tell you where to check for power, ground and continuity.
