    hey everyone im new too this site. I have a 2002 F350 powerstroke, i bought the truck a few months ago installed used pushplates and a brand new truck side wiring harness for my 8 ft mm. i went to go pick up my plow the other day and plugged in the grille connectors and nothing works, headlights dont go on motor dosent go on, plow wont move.The only thing that works is the light on the joystick, plow worked great last year on my old truck. i wired my old truck for the plow by myself last year first time and worked right away. any help would be great, thanks

    well you might have a gnd issue. check your grill connector (the main pwr and gnd one) MAKE sure you have pwr. ck it with a test light. if you have it there, hook the plow up, connectors and all. and ck for gnd at the motor terminal.

    Ihave replaced the plow side power cables on 2 of my units for loos of ground. Wat to check is hook jumper cables off your battery direct to the motor,obviously unpluged from the truck if the motor goes then one of the cables is likely bad truck side or plow side.

    I jumped the motor and it moved thank god, I now remember when I would hook up the plow to my old truck I would have 2 wiggle the ground cable to get the plow lights 2 work and the plow also moved fairly slow. I will be going to my fisher dealer tommorow too get a new ground cable.
