Start by testing the 3 pin truck side plug with a test light to see if you are getting power st any of those pins when you operate the controller. It will take 2 people

 

What cwren2472 said, now if you cant get any help. make up a few sets of aligator leads, then use them to extend the connections at the plow unit, check the ground wires for the magnets. Here is a wiring diagram manuel.

Thanks for the hint. I checked the 3 pin plug which ends up at the coils. I check on a voltmeter ground to black and red to each of the 3 pins which I assume are left right and up and found no voltage anywhere when moving the joystick. So no power no good. I'm now guessing! a bad joystick but hard to test unless I gamble and buy a new one. Any words of wisdom are greatly appreciated.

Thanks.......Greg

Did you check for power at the controller plug while operating it?

 

There is power. Red light is on, motor runs but no plow movement.

 

Power in and none out, replace the controller.

 

A friend found the problem. The person who installed the plow ran the cable through the firewall did no protect the cable from the sharp metal with a grommet and the vibration ate through the cable and cut the wire that goes to S3. Once repaired all is fine. He also bypassed a fuse! Thank you for help with my problem, I truly appreciate it.
