    i acquired an old meyer plow with an E-47 pump. it worked fine at first but started acting up.
    would come up but go to default position. took pump to "so called repair shop" they tested pump and said it was fine, i would get it back and it would work for awhile and then stop lifting and i took it back and said not working. they tested again and said it is fine. i would then hook it up and it would work for awhile and stop.so i am trying to figure out how to determine what is wrong with system? or where to troubleshoot.

    I use the e-47 with a slick stick and i had some problems with it it was the slick stick controll mine was cracked where the prongs are i rebuilt it myself the pump changed out th motor and replaced the b cly. An valve also i had a problem with my wiring i had changed that also

    it works so good since i rebuilt the pump i bought the new meyer lotpro w/wings and i am using the e=47 still

    if the shop said its fine look at your truck
    try this go buy a new controll if its still the same then it will be your wiring from the pump to your controler

    If you are lighting the overload light on a touch pad you need to re-establish all the grounds. This is a common problem w/ Meyer lift units. Also, do you have the star washer between the base and cable and NOT between the bolt head and cable. See this one as well cause ground problems.

    lon is right on the money. poor ground will trip overload all the time. spray wd-40 on all of the valve coils. remove and clean all power connections.

    you would be amazed at the # of times i have charged people to tighten the battery cables.

    ok, put on all new cables, checked the grounds clean off all connections.

    i can move plow left and right no problems, now when I hit up to lift plow it immediately starts going to left.
    i can move it all the way right and then hit up to lift plow and it starts going left.

    is this a valve problem?

    is red wire getting power?
    If you have power @ the red wire next check for magnetism @ the nut on top of red wire coil.

    It could be corrosion between coil & valve as well. Pull coil up off and see if there is rust on top of the valve where the coil sits down on it. Scrape any rust off and re-try.
