    one of our ultra-mounts will not raise. when raise is selected on the controller the plow angles full left exactly like having the controller on the left angle selection.

    it is not the controller as we have tried a few. it is not the truck-specific wiring as it does it on three trucks. it is specific to the plow.

    sometimes it works just fine. sometimes it will not go up but angle right and then a couple tries later raise like there was never a problem. then maybe it will not raise at all no matter how long you try or what you do and just angle full left instead.

    it is likely the 9-pin connector, which we have cleaned and greased to no avail. or it may be one of the solenoids is bad.....

    trying to figure it out and the local dealer is backed up two weeks........

    found it. a sliver of metal was blocking one of the holes that directs the fluid to raise the ram.

    cleaned it out and all is well
