When I hooked my plow up last night and tried to raise it it turned right when I hit the up button then I tried to turn it left and it went right as well. The motor runs and plow moves to the right fine when up left or right buttons are pushed. During our last storm it did this once and I hit the control a few times in different directions and it started working normally again, I thought it was a fluke and I could not duplicate the problem again. It worked fine last year and I have never heard of anything like this. I did put dielectric grease on the connectors and nothing changed. It worked normally the first storm of the year and the only thing I did to my truck this year is put in two new batteries but it worked fine after I did. This is a 3 wire ultramount. Any help appreciated! Thanks!
