    Hi guys I just finished hooking up all my plow wiring and mounts and found that when i plug everything in that when I try to move the plow the blinkers shut off and I also found that my main ground wire that goes to the pump motor gets very hot. Oh and the plow will not move at all. Need some help

    Thanks

    know I have it so if i put a tester on the + and - on the motor it will move the plow but the ground is still getting so hot it started smoking but this is only at the connection from the plow to the truck.

    Assuming you have your positive and negative hooked up right then I would say you have a ground somewhere. I would check your connections for a ground and maybe test your plow pump.

    well the plug only lets you put it in one way and looking at the wires they both match up and for my last post I can get the motor to work. Would a bad motor cause the ground to get that hot??

    Connect a jumper cable from your ground on the motor to the ground on your battery. Then try it and see if it acts normal. It sounds like there is a bad ground connection somewhere.

    What did you end up using for an accessory power? Is this a relay system or do you have an ISO module system?

    I just used one of the fuses that turn on with the truck for the accessory power. and it is the 4 port Isolation Module and it also has a relay

    Relay, or Solenoid that connects to the battery and your control harness?

    I'm fairly confident in saying that you've crossed something some where within your install. The fact that your turn signals fail to work after engaging the plow....something isn't right. For the most part they are 2 totally different systems in one.

    Have you researched which socket you used within your fuse panel?

    ok what would you say I crossed and I used the fuse for the "ignition run power feed"

    That's the question of the hour........

    Start from the obvious points. As PlowGuy43 had mentioned, run a set of jumper cables or leads straight from your battery to your appropriate terminals on the plow motor, and try and run the plow. What happens?

    I think you guys are right about the ground being bad I hooked it fast to see if it would work and it seemed to work. Im going to work with it more tomorrow. I hope I dont have to replace both wires but oh well Thanks for all the help
