    E-47 was working now nothing, no side to side or up or down. I can hear the solnoid engaging under the hood but still no worky. Has fluid in pump. Died right in the middle of a job.

    Have some push up while you hit motor with hammer lightly. Also can test output side of solenoid for power while someone else operates plow control with test light.

    My buddy was tapping the coils as i was hitting the up lever. Nothin. Didnt try the motor on the pump though. What are the chances the motor on the pump took a dump?

    my bet is a bad ground.
    use a test light instead of a hammer. test light tells you if you have power. hammer breaks things.

    Is motor spinning?

    Hammer could possibly get you home without short chaining, most likely a test light won't. Also very common practice to tap motor with a hammer. Not to mention that hammer test is much quicker.

    Actually new update. It works, just very slow and angry sounding and then it'll stop working... Air in the system or fluid problem?

    Run jumper cables from battery out to the pump. This will tell if it a motor/pump problem or a wiring problem.

    Turns out the pump was frozen. Unthawed it and drained fluid and cleaned filters. Didnt last long though as this morning around 3am it froze up on me again. Anybody have any tips on how to figure out where moisture is getting in??

    Common places for water to get in is top wiper seal, ram packing and reusing the nytite washers.

    Yeah I noticed today its leaking out of the top seal and running down. Anything else I should do when I replace the seal? My buddy has a seal kit left over from one of his E-47 he didn't use so I'm gonna buy that.

    Unused kit? Pump shaft seal is another place to check. My biggest gripe is people reusing the nytite washers. They never seal properly when reused.

    Yeah I'm pretty sure its a unused kit. Ill have to look into those issues, everything else seems to work just besides the moisture..

    If you are gonna pull it apart might as well do the entire pump. Download the service manual and read it, then read it again. Clean everything real well. And be sure to flush out rams and hoses.

    and a very common after effect of hitting the motor with a hammer is breaking, or dislodging the magnets from the case, ruining the motor if it was still good.

    +1. Permanent magnet motors don't respond well to the hammer

    Haven't broke one yet. But if you wish not to do it that is fine. Besides no one is saying break out the ten pound sledge and go to town, I said tap it lightly. So if you guys want to preach the hitting a motor with a hammer have at it. Would be willing to bet you have done it at one point or another, whether it was a plow motor or a car starter. :salute:

    nope, never did it Kimber, because i have seen so many come into the shop busted after the driver said" i hit it with a hammer to get it started one last time"

    Guessing you are in the minority. :mechanic: Had an old Jeep that hitting starter was the only way to get it to crank, was this way for months until finally got around to putting starter in. But I will say once a motor gets to the point it needs persuasion to get going it is time to replace it anyway.

    I beat on gas tanks also with a hammer, whats your feeling on this.:laughing:

    A driver isn't a tech.....And if the magnets fall off due to hitting it, they were on the verge of falling off anyway imo

    that is a different story.
    smacking the bottom of the gas tank is the only way to get the in tank electric pump started, ain't it??:D
