    Won't go right no matter what I do, if I toggle right it keeps going to the left. I've replaced all coils and quick couplers. Won't lower and bleeds down but I'm 90% sure I have to buy a new A valve to fix that. I bought this unit off a guy I work with and I think it has sat around for a couple years unused. I finally got it to raise after I was told the B valve should have a spring and ball under it. ( I checked and it only had a ball, no spring). Is there supposed to be a ball and/or spring under the C valve? I also don't know where the crossover relief vave is or what it looks like. I'm just trying to identify the problem so I don't have to " throw parts" at it untill it's fixed anymore. It's getting expensive,moneys tight these days, and the wife is bitchin everytime I take her Walmart money to buy more plow parts.
    I think I need a new A valve and a new C valve. If there is any way to clean these or if my problem might have something to do with the crossover relief valve I know nothing about please let me know so I can get this thing figured out.
    FYI, the O rings on C vave SEEM to be ok
    Thanks in advance.

    Did you check the C coil for magnetism? If not be sure to do so. May not be anything more than a loose connection on the green wire in the harness.

    While you had the C valve removed did you stroke the internal spool to be sure it's free to move? If not you'll want to do that too.

    Yes, The C coil has magnetism. I used a helper and touched each coil with a wrench to check.
    Only thing I did to C valve was make sure the outer shaft the coil slides on wasn't bulged, I blew out with an airhose real good, and bolted the coil to it while removed and touched it to battery posts. It clicked pretty good but I didn't notice anything moving internally. Is that normal?

    OK, update.... I disassembled C valve, cleaned, reassembled and it goes left,right,and up now! Now the only thing wrong with it is it won't lower. I removed and cleaned the A valve hoping to get lucky but it still won't lower however after cleaning A valve the lift cylinder now holds strong and doesn't bleed off at all. I'll do some searching on this problem and start a new thread on not lowering if I can't figure out. Thanks B&B! You already saved me some Walmart money for the wifee!

    Go back to square one on the A valve using the same test procedures that you used on the other valves. Check it for mag for starters. If it has it, replace the A valve as it may be stuck closed now. If it has it but it's weak replace the coil. So don't spend the cash at Wally World just yet. :D
