    After the plow is up in any up position it will slowly lower until it is on the ground key on or off it may take a minute or ten but it WILL end all the down on the ground,

    I assume this is a western isarmatic pump ?

    Just had the same thing,happen to mine. The s1 valve was about $45 and immediately fixed the issue. Torque on the valve is 10 fl lbs, and the coil is 4 ft lbs. Lube the o ring with plow fluid before torquing. I used my inch lb wrench and made it 120 and 48 inch lbs respectively

    You want to make sure you're inspecting the valve for debris when removed. Replace the fluid while youre at it would be beneficial

    Have fun

    Its in the mechanics guide. If you have the isarmatic pump,as i mentioned before, under the cover where the 3 coils and valves are housed, its the top right valve whereas two valves on top, and single on left bottom. Call your local supplier as most of them know the part number already. Wouldnt be a bad idea to change the coil on it as well if its never been changed, or if you have an ohm meter you can test it. Easier to spend the $18 and just replace it
