    So I Changed the GPR on my dump yesterday. I unhooked the neg. cables from both batteries and went about my business. I went to hook the plow controller up and it doesnt light up. So today I was poking arround with the test light, and when I touch certain wires, the controller lights up. So my thoughts are that there is no ground some where and when I touch the wire with a grounded test light, the circut completes. Now the harness that is on the truck had some splicing in the brown/red and the orange and black wires. So I cut them apart and soldered them together. Sill they didnt work. So my question is, Would a bad selinoid cause this? Because the one that is on there is used. Any Help is appriciated. Thanks.

    It should have had an orange/black wire on the neg side of one of the batteries to ground the harness and under hood solenoid... you might have over looked it when you reconnected the batteries..

    Well. Upon Inspecting it today, there was no extra ground. I added one, and when I did that, the headlights dont work now. I had the same problem when The dealer first put the mount on the truck. I took it back, and he removed that extra ground, and then everything worked fine. So why would it work fine until I took the neg cables off of the battery?

    BTW the plow lights do work. It acts like the plow is attached all the time. You turn the lights on and it automatically switches. Relays are new too.

    How many relays are in your harness, 2 or 3?

    I'd be going back over any connections to make sure you didn't bump one loose..

    Grounds appear to be ok. When I took it back to the dealer, he told me that sometimes the joystick controller wont work, but the handheld one will??? Thoughts?

    Still sounds like an intermittent ground problem on the org/blk wire somewhere...

    Since you mentioned before that the truck harness has had some "splicing done in the org/blk wire" that'd be the first place I'd be double checking.

    When the controller does appear to have power, does all the plow functions and head lights work correctly?

    Yep.

    I dont know what grounds exactly to look for. I gave it a check over, and I didnt see any lose/broken wires.

    Wasnt anything a 9 pin repair harness couldnt fix. There were a couple broken wires. Just wish I could have done it myself. Oh well. Good to have a good relationship with a dealer.
