So I have an old fisher minute mount 3 plug. Last storm the hydraulic pump fried. Replaced the pump, worked great at first but then started to have issues. I would move the plow, but after I let off the switch the pump was still running, only way to get it to stop was unplug the plow. I assumed it was a bad selenoid not cutting off the power to the pump so I replaced, and still same problem. I now notice that when it does stick, it’s only when I suck the drivers side of the plow on. Doesn’t happen every time I move it but frequent enough it’s annoying. Any thoughts? Was thinking maybe an electrical short in between switch in cab and selenoid?

Next time it sticks, un plug the controller and see if it stops, if yes, bad controller, if no replace the solenoid, which I would do anyway cause they are not made to be in the closed position for that long.

Okay so a few things. It stuck again. I unplugged controller, still does it. Replaced the solenoid twice, still does it.
