    I have an E47 on a Meyer blade. New A coil, new A solenoid, new B coil. Tested A and B solenoids with the coils, all functional.

    Put them on the pump, plow raises fine. Will NOT release. Now...I have the switch wired to a fuse that is 24/7 hot. Is that the problem?

    Secondly, is there supposed to be a ball bearing in front of the A solenoid, so that when you screw the A sol. in, it has the ball bearing between the A and the hydraulic fluid? I ask because there isnt one in there, and there was with B.

    a coil went bad or valve stuck shut... a coil has no ball bearing swith should not be wire hot because it could run battery dead if left on also it could burn out a coil if left on in down mode b raises a lowers c angel pull a valve turn upside down stick little screw driver in it and push in and out clean with deasel feul .. it will go in and out a little if its stuck replace... all thats in them are spring and ball bearing and coils open them

    when I mentioned the bearing, I meant in front of the A solenoid when you thread it in. i didnt know if there was supposed to be one there. coils are tested and working 100% as they should. solenoids A and B were tested and working.

    it has the toggle switchs for control. we traced wiring and tested the switchs, wiring is good, switches are good.

    can call anytime ive been their i would think for it not to drop it has to be pluged up or a valve stuck shut it dont take much check filters does it have 2 or 3 plugs on front lower section of pump 1 will drain outher 1 or 2 are filters check and see if coil is magnatizing when switch is on if you try to take out a valve with pump up it will come crasing down put something under it befor you try to take out a valve i bet its not geting magnatized or valve is stuck
