    I have a fisher mounted on a 99 f350.I started the truck this morning and when I went to raise the plow, it came up as usual. When I tried to angle it the controller turned off. I was able to lower it, but when I try to raise or angle I hear the solenoid click and the controller turns off. I'll take any advice, because we have a bunch of snow coming tomorrow into Monday!

    ik, i wanted to clean my truck out considering its trashed from plowing so much lately but its not worth being out there. i agree with quigley, it could be ground wire or something

    I just replaced the solenoid, it still isn't working. Battery terminals are good. Could it be ice in the pump?

    Not sure about ice. Could your controller be bad? I know my western controller went bad and it would raise and lower but only went right. If you've got a buddy that has the same controller you could test it out

    Ck where your controller power wire is tapped into. It might have wiggled loose. Also Ck your controller connector itself, wiggle that and see what happens
