    Hello, New guy here, and with plowing. I bought a 1997 Ford F-350 last year with a 8' MM plow. Worked great all year, but when I hooked it up recently, the control box inside the cab had no power to it. The light wouldn't light and no movement with the controller. I checked all connections I could find, and the two fuses next to the module were hot. I am electrically challenged, so I've done about all I know. Does anybody have any ideas? My next step is to the (gulp) dealer. I think the plow is about 1999 vintage. Thanks, JW

    First, try jiggling the connector plug - you may have a flaky connection that could clear itself out with some persuasion. :)

    Second, do you know how to work a voltmeter? If so, you can test out the wire in the harness that should have 12 volts going to it when the truck is on.

    Yep check the connections at the plugs and battery first. Get some dilectric grease and make sure all conections are clean. And check that ground wire that goes to the pump. That cost me an hour of frustration one day. Has the truck ever had the cables replaced. I had to replace all four of mine. So get a buddy to sit in your truck while you wiggle wires. This is a common problem for the MM

    Possibly a bad controller, bad ground or follow the red lead off the number one harness that goes into the fuse box inside the truck...like mentioned before check all other connections too.

    the connecter on the end of the controller wire can be very fragile and one little fray or seperation in the connector or the connecting wires could make it not work. Try to get a hold of another controller that ya know works, and try it.

    Also, try closing up the female end of the controller connector.

    One more thing to mention, the controller will not work unless the headlights on the plow are connected and work.

    oh extensive use of the search function Mike :) I noticed your post cause I had emailed you about a buyers tailgate spreader you had for sale a couple of months back on craigslist. I think it was sold time I got through to you.

    My wife is from New Hampshire, Nashua in fact. I lived there for 5 years. I bought my plow rig down there recently.

    Thanks for your help, keeps me from 100% learning the hard way!
