    I've got a straight fisher plow on a GMC Sierra 3500 & the plow won't move. The fish stick won't even light up... checked the fuses and connections. Any ideas?

    Blade. Which plow do you have MM1 or MM2? Iso Module or Relay setup?

    Double check your connection at the grill to ensure it's seated properly.

    Have you checked you accessory wire to see if the fuse is blown? It will be inside the cab running off the end of your control harness.

    Also check you solenoid for any corrosion or broken wires. And again at your battery.

    Double check your control harness connection as well as your controller.

    Then try this if all of that doesn't turn up to be th culprit:
