Hey guys, first post here for me. I ended last season needing new battery connections finally just got around to getting it done. Well after doing that I had no power to my plow controller (boss joystick. Super duty 8'6") after some searching I found the add a circuit fuse harness in the fuse panel left side of the dash had melted. Replaced and put in a new add a circuit, bam controller power restored. Now here's where I get lost. Go to hook up to the plow and the power tach doesn't work. Motor runs but mount doesn't move. I pushed it up and locked it in manually. Plow goes up, down, side to side fine. Start driving with plow lights on and they start what seems to be shorting out? And flashing back and forth from plow lights to truck headlights... all the while the light on the controller is also strobing. My question is, where the hell do I start looking?
