    I have a MM1 on a 2001 F250 with a fishstick controller. The controller has power and I can hear the motor solenoid clicking, but the plow does not move up or angle. The plow lights do not work either. I verified that I have 12volts at the plow to vehicle motor connector. I think the issue is further back in the system though since the lights dont work either.

    What will affect the lights and the valve controls??? Thanks.

    Thanks for pointing me in the right direction... thats exactly what it was. Threw me off because I had 12v to the motor via the bad ground, but I guess there was enough corrosion where it wasnt getting any current..
