    A friend of mine is having troubles with his truck.He's not around me so I can't go look at it.The problem he is having is the truck switches back and fourth from the plow to truck causing an almost strobe pattern.Any ideas?

    Connection issue for sure. Loose, bent, or corroded connection at the grill, ISO, or solenoid. The ground is connecting and missing with the vibration I would think. Have him fully inspect the pins on the 11 pin light harness (both sides obviously), unplug and re plug the connections at the ISO, but more importantly, trace the black / orange wire that connects off the light harness...I'm assuming this is a 3 port setup, but I need to know what plow to specifically tell you where to look for the connections. It ultimately lands at the solenoid, or battery depending on wether it's a multiplex or non multiplex setup. Again, depending on the setup, there are a few barrel connections along the way as well.
