    could be the controller, but it also can be the 3 pin harness. they break alot right near the plug "where you grab to plug or unplug"

    yea it ended up being the controller after cleaning every single wire . checking all the connections and cleaning all i could in the hydraulics this morning it ended up doing it trying to lift the plow if i pushed real hard on the controller it would go up so kind of gave away what the problem was wish it did it before.... so $200 later i got a new control board and it works great
