Hey guys, just put on my plow and am having some problems -- electrical I think.

Description: Get in the truck, turn power on the controller box and raise the plow. Sometimes it works and sometimes it doesn't. When it doesn't, the controller box displays an illuminated red lightning bolt.

Partial fix: Get out, disconnect the electrical connection, reapply it and jiggle it around. Sometimes it fixes it and sometimes it doesn't

Attempted fix: I went out today and bought a can of electrical connection stuff that you spray on and it a. lubricates b: improves connectivity c: displaces water d: prevents corrosion. I left the stuff on for the recommended 4 hrs. before re-energizing, went outside and the plow worked great. Up, down, side to side a couple of times and then again; the red light came on and the plow wouldn't move.

It was just recently mounted (by pros, not me). Haven't had our first snow event yet but I'm afraid I'm going to be screwed if we do get snow. How can I troubleshoot this better?

Thank you in advance and Happy New Year.

Steve :crying:

More info...

Alright, after an afternoon of intensely staring at this, I've discovered that it's probably not the connection. Throughout the day, I've been able to duplicate the problem without moving/touching any wires. I turn the touchpad on, it illuminates without the red light. I move the plow up down side side a few times then suddenly the red light comes on and no more function.

After turning the touchpad off & on a few times, the plow suddenly functions; sometimes only for a second and other times for a few motions of the plow. But, no continuous function.

Theirs many reasons that can cause the OL light to come on on the touch pads... but usually only 2 causes... either the TP itself is defective, or theirs too much electrical resistance in the control function circuits somewhere...

The first is easy to troubleshoot, try a different TP.

The resistance problem is a little tougher to find.. could be as simple as a loose connection at the controller plug, the orange ground wire for the TP, the under hood solenoid.. or one of the coils.

If it seems to do it no matter which function you press (up, down. left or right) then I'd be checking the orange ground wire first. It should be either directly on the neg battery terminal or on one of the mounting bolts on the under hood solenoid.

If it only seems to do it with a specific function (only up, only left etc) then I'd be checking the connections and coils for that specific function.

If it only does it in a position that the motor runs in (under hood solenoid would be activated) then I'd be lookin at the solenoid as a possible cause...(defective or a poor connection).
