    I thought I responded to this.. must have been eaten by the database moster??

    Your joystick may be gummed up. Take it apart and clean the contacts.
    Use alchol or a good electronics component cleaner.

    Check Your Hoses And Ram Seals For Weeping Or Leaks. It May Need To Be Topped Off.

    We checked for leaks, connections tight, springs good, Does it matter if i used trans fluid instead of Boss Plow fluid?

    valve body

    If the plow goes up then the fluid is ok. I used auto transmission fluid in my Fisher with no problems.
    Did you make a repair that could have caused the problem?
    You should not be able to move the blade with your hand. Even if there was air in the system, you should not be able to move the blade.

    1. Stuck solenoid valve in the open position. This would allow you to move the blade with your hand due to the valve being stuck open.
    2. I am not familar with BOSS but if there is some sort of computer chip then it is possible that it is damaged and somehow telling the valve to stay open.

    I suppose if you can still move the blade with the truck off and the power disconnected from the plow assembly then you have a stuck solenoid (1). Try a hammer on the valve assembly... NO KIDDING!! Gently!

    We need to first determine of it's an electrical or a hydraulic problem.....

    You said that it goes up when you try to angle it right or left correct?

    Ok, The first thing to check is if when you try to angle it right or left, is the lift valve energized? (the lift valve is the one with the white wire)
    Check it with a wrench or screwdriver for magnatizem.... if it does have magnatizem when your trying to go left or right, then it's an electrical problem.

    If it doesn't, then it's a hydraulic problem.

    Glad to be of help

    I looked at a plow parts book that I have and it shows that the solonoid valves are horizontal. This is a poor design by all manufacturers. Solenoid valves are best in the vertical position so the coil moves the piston up or down and gasket seals wear evenly. There are still times that a piece of debris will block the piston however the leakage past the valve is minimal and eventually gets flushed away.
    A horizontal design has gravity working against it where the six oclock position of the piston and seals are constanly being worn. This is where debris gets caught up and does not come out easily.

    Another issue are normally closed circuits where coils are always energized. Energized coils are HOT and over time break down seals. GUMMY seals attrack debris!

    Nothing beats levers, cables and manual valves!

    It's good to see that you have your investment back up running! Add the hammer to the other tools sliding around the back of the truck.
