    Hey guys, I just picked up a used mm1 3 plug 8' HD. It needs some loving but the blade is in perfect shape with the exception of a small bend and the head gear is in pretty good shape just is slightly crooked too, but the deal was right ($650) and this is my first plow so if this season pans out with clients i'll graduate to a nicer unit next year and use this one as a back up. Going to put a fresh coat of paint on it and flush the fluid and slap a new cutting edge on and see what she will do this winter. payup

    My question is the lights turn off whenever i adjust the plow, up down left right the turn off then come back on when i left off the button. My truck has a fish stick and its not the truck side wiring because i have hooked up to other plows and it works fine. Any ideas what this could be? Thanks guys.

    I'll take a look, I also noticed there are no running lights or directionals....just headlights...hmmm are there light wiring diagrams out there?
