    I have a mm2 on a 2001 dodge 2500. Tonight I was plowing and the entire plow started vibrating and I had no control over anything (this has happened before) I ran around and unplugged everything but before I could it rained my battery. With everything unplugged I charged the battery and restarted the truck. Plugged everything back in and nothing works. I do not have a light on the controller and nothing will move. Please help me snow is coming tomorrow.

    I would start by having your battery and alternator tested. Check the fuses in you harness and make sure all your connections are clean.

    are there fuses for the controller? How many fuses are there in the harness and approx location of them? I will check the connections, I know the battery is good and the alt is fairly new but I will have them checked.
