    I attempted to hook up my plow today for the first time before a storm tomorrow and when I went to pick up the plow all that happens is the lights dim. The up/down ram is down and the chain is loose. Fluid is full and changed toward the end of the season last year. No problem with it last year. It's an 8' plow on a '04 Ford superduty. Snows a coming - please help.

    don't we all wait till the last minute. I just love pushing the white stuff around - at 3 different houses all with long driveways and garages and barns and turn arounds.

    does the motor run or the solenoid click? start at the battery and check all connections for corrosion and being TIGHT. any loose connection will kill it. clean the 9 pin connector with brake clean and blow out with air.

    My guess, it's a stuck relay. Just hit, I mean tap, it.

    There will be one main solenoid that powers the whole system, is this a MM1 or MM2 system?

    Are there 2 wires to hook the plow up or 3?

    any bad connection outside can cause the plow not to move

    but what is making the lights dim and motor rpms go down when trying to move the plow in any direction. doesn't seem like a bad connection - more like a bad or frozen pump motor. I could be wrong???

    get a wire tester! and while someone is pressing up, see where you are losing power. I would suspect that it is in the selenoid under the hood. prob blown or not getting juice. But first, check your fluid

    I can hear the solinoid on the insde of the fender click when I move the lever. I can only move the lever for less than a second because the lights dim way down.

    Just because it 'clicks' or 'clunks' dosnt mean its working! It soudns like a short and your loading the whole system.
    Get a meeter or at least a test light to find out whats going on. Motors are expensive, its much cheaper to spend some time on it instead of throwing parts at it.
