    Ok, so we just got this plow jerre-fied before the season, its been working great and now developed this issue:

    when angling left, it stops intermittently but sounds like the pump is still straining to angle
    it will then continue normally and then repeat the stopping throughout the travel left.

    it only does this left. sometimes it will completely stop and not continue, then you angle right and repeat and its goes back to angling left with the intermittent stopping.

    stuck valve, solenoid? any way to troubleshoot this?

    Sounds like a bad connection in the plug or harness. Test light and wiggle the harness around. You'll probably find a bad wire.

    Swap your coils side to side to confirm if a coil problem, then do the same for the valves.

    How old is the plow? if you unpin the angle cylinders with the plow raised, can you pivot the blade side to side freely? A high hour plow may have some irregular wearing in the Aframe bushing and center pin bolt area causing it to catch.

    First thing to check is the plug connection. When it's colder out the harness gets stiffer and can cause intermittent problems with connection. Another thing that we've seen is sticking of the angle cyl where it can cause a slight bind. Your problem sounds more electrical than hydraulic though.

    Have someone out front to wiggle the connection when this happens and also remove the cover and check the blue wire and it's mating red wire on the 10 pin plug under the cover for a loose pin / connection. Pull / push both sides in the plug to make sure they are locked all the way in.

    would the motor still pump if its an intermittent electrical issue? like i said, when you go to angle left, the plow will stop but the motor sounds like its still pumping fluid then it will "un stick" and continue through its movement.

    ill check the plug soon, its 0* with a cold wind chill and dont feel like working outside rightnow. ill keep you guys posted.

    It could. The pump runs by the control of the main truck side solenoid (brown wire energizes the solenoid) The valves on the manifold are controlled individually and simultaneously to the motor activating. Check for current at the blue wire all the way through angling, back probe the rubber plug at the 10 pin connection.
