    Hello, I have a 2012 Fisher Xtreme V - 7.5
    My problem is I have a flashing red light on my Fishstik, with no plow movement Sometimes. It seems like it is intermittent, but is happening more often now. It has all worked perfectly until yesterday, and I have never used the security guard feature.

    Things I have tried:
    -Cleaned and applied dielectric grease to plugs in grill
    -Tried a Fishstik from a friends V-blade. Still does the same thing
    -Slightly bent pins on controller connector to make sure it has good connection.

    Thanks for any other help In advance.
  2. You're on the right track....a flashing red light means the truck is having a communication issue with the plow. It's usually the two very small pins in the battery cable that goes to the pump motor.

    Do you mean the square 4 pin that goes to the front of the truck?
  4. Yes there are two very small pins in between the larger pos and neg pins on the battery cable. Those two pins do all the work of controlling the functions on your plow.

    The pins look very clean and I have dielectric grease on them as well

    I also just tried a known working vblade on my truck and that one doesn't work either... Just flashing red light. That leaves me to a problem on the truck side

    Definitely sounds like a truck side issue
  8. OK so work your way back on the battery cable towards the iso mod. Those two wires have a plug on them about halfway back. Check that and work your way back to the control harness. Check where the control harness goes through the firewall for a chafed wire.

    Hello everyone, I found my problem, thanks to this site. The brown and white wires (2 small pins in between big pos and neg pins) from the grill plug were chaffed off on the truck side. Put in new wire and everything is good.
    Thanks again!
    Now maybe someone can tell me why my low beam lights don't work? Lol
    Thanks again

    Glad the problem is fixed. It is a very good idea to get some hard plastic conduit to wrap that power harness to prevent the communication wires from rubbing through again. They are very vulnerable behind that thin weaving. Even a zip-tie is enough to rub through.

    As for your low beams... do the low beams work properly on the truck? Always start with checking the fuses off of the isolation module as well as the fuses on the truck. Are all of the pins still in your 11-pin plug? Do you see any broken wires around the 11-pin plugs (both truck and plow side)?
