    i just put an extreme v on my 06 dmax. the plow is used but i saw it working before i bought it . when i use a different controller the plow works fine but my controller doesnt. when i turn it on the light blinks but no response. is the controller bad or could it be a simple fix?

    Well how new is the plow? Does it have security guard on it?

    It could be your controller is bad, if other 4 pin v controllers work

    plow is an 09. ive tried hooking the plow up to a security locked truck and controller and it still works. the plow works on my truck with the security controller and an older one so thats why i assume the controller. the power light still blinks though

    it works with a different controller so i figured it bad. just didnt know if it was a simple fix in the controller that i could get worked on or if i should just buy a new one

    If it is a four wire plug the problem is most likely where the wires go into the base of the controller.

    The four wires are cheap and small in size and break easily, I have fixed mine three times in five years, finally I grew tired of fixing it and took it apart and soldered in a" four wire" speaker wire replacing the whole harness from the controller to the plug.

    Since I upgraded the wiring it has worked fine.

    Use a continuity tester and I bet the wires have no continuity or a few do not.

    Good Luck

    is there any way to test them all at once? since theres the possibility that the controller is bad should i open it up and then try and pin on a tester? otherwise im not sure how to test the whole system. thank you for the help so far.

    Testing them all at once wouldn't reveal an individual failure. Test each wire one at a time

    how would i do that? plug the tester into a positive lead and then try each one of the four leads? sorry but my wiring skills are lacking

    Sorry to say but if ur wiring or electrical skills ain't that good,,,let a pro do it. U can fry a controller if u pwr or gnd in the wrong spots

    Open the controller, AT YOUR OWN RISK, carefully unplug the connector from the circuit board and then use a continuity tester to ohm or tone each wire from the controller connector to the harness connector and check the wires one by one.

    If you have an open circuit or no tone then you have a bad wire.

    The break usually occurs where the controller wires exit the rubber boot at the bottom of the controller.

    It is a 15 minute fix, all you need is a digital tester, a test light won't work.

    I had the same problem... Green wire was broke. Just splice it back together and good as new... Until the red black or white wire breaks LOL


    Did Fisher fix this problem? Are the new V controllers still 4 pin?

    A New coil cord is part number 96464, it could be the cord or PC board....

    A rapid flash indicates that security guard is active.

    A slow/steady flash means no communication between the control and plow module.

    Could be anything in between but we know it is the control since you has success with a different control obviously.
