    I have a Buyers tailgate salter with hitch mount I purchased new last year. Lately it is driving my crazy b/c every time I install it on my truck, the motor spins the opposite direction from the last time it was on the truck. I put it on, it spun backwards, I switched the power wires at the motor, it was fine. Next time, same thing, put the wires back to stock, fixed it. Yesterday, put the salter on, its backwards again.
    DC voltage, I can switch the wires to make it go one way or the other, BUT, the plug from truck to salter only plugs in pos- pos, neg- neg., there is only one power wire tracking from the power supply to the salter, the ground is at the frame of the truck in back, therefore no way power can be switched unless the wires are manually removed and reinstalled at the motor, under the plastic cover.:dizzy::cry::dizzy:
    Any suggestions?? New motor, probably??

    Maybe it's the variable speed controller? Wierd, never heard of a problem like that before.

    There should be a ground in the back where you connect the spreader wires to the rear connectors and there also should be a ground coming from the controller to the truck also. IF you have both grounds and it is still doing that then it would most likely be your controller. if it was short your controller would most likely overload and shut off. but first make sure you have two grounds.

    Per the wiring instructions, no ground goes up front, One power wire runs the length of the truck from controller to plug at rear of truck, One ground on truck side of plug grounds to frame of truck. Salter side of plug just has corresponding power/ ground wires that lead directly to motor. I dont see how it could be the controller, unless it somehow feeds power through the frame of the truck, and retreives ground through the power wire?!? :cry:
    I'll keep trying to diagnose it and let you know if I come up with anything. :waving:

    i would say it could also be in your controller as i have had 2 of them act up before, now i hard wire them. Mine would work intermediatly and smoke up after awhile. also check the wire connectors at the control box and see if they are shorted/burnt.

    also, in the box there is another ground that is prone to coming loose and shorting out later.

    Actually there is a ground for the variable speed controller. If it's not hooked up then that could be the problem. But dunno.

    that is what I said about there being a ground for the controller. I just installed one 4 days ago on my buddys truck. You should call up buyers and ask them what the deal is...

    Ground is always a problem with these things. They are chasis ground - and I was told they're looking at changing that.

    If you're worried about it, just a run a ground wire from the spreader to a good ground. You can do the same with the controller.

    Never heard of that direction switching before - that is bizarre. The control only puts out positive voltage, so I'm not even sure where to start on that. The ground is definitely the best place to start.
