    The plow has to be hooked up and the truck on, or atleast the key turned to the on position.

    How old is the unit? What kind of wiring system.

    Yes, the red wire powers the unit, but it grounds through the plow harness.

    As above if the plow is not hooked up, the controller will not power up.

    Controller is the issue then. If the lights switched over to the plow, then the ISO is working properly.

    Get a new controller, go to your local dealer if you have to, they typically will let you borrow one in the parking lot to test it out. Just short chain the plow to get it there.

    A few tests if you would like to be convinced for certain.....
