    A coil not getting power. black wire. A valve not shifting.

    you need to see if the a coil is getting power. it is the black wire. if it is, does the a valve shift? you will have to take it out and look at it..

    put a jack under the plow. when you pull the a valve the plow is going to come down.

    and it will spray fluid all over from the valve hole.

    to test if its getting power you will need a volt meter or test light. from the black wire to ground and some one to work the controls

    WATCH OUT if they move the wrong control or you are in the wrong place you can DIE, you can get crushed by the plow it has a lot of power

    Would some one explain to me how low fluid level will prevent a ram from collapsing

    i wish i knew. i filled it up this morning with fluid, went out and came back a few hours later and it works perfectly for me now. don't know how it would prevent it from collapsing but it must of.

    maybe it had water in the coil and it finally melted to free up the coil...mine have been having that problem recently. in a p[inch i use a mapp gas torch to heat the coil a little and the pump and it ususally unthaws.

    I was going to say water because low fluid cant prevent the ram from lowering

    Most probably is water in the hydraulics,it froze up on your way home and thawed out with the addition of the fresh ...warm?... oil. Repeatedly cycle through all functions on the plow and then check to see if the fluid is cloudy, if so drain the pump and cylinders and replace with fresh blue fluid.

    cheers and good luck
