    alright, i put a new boss plow on my 2003 f250 last fall. this spring, it wont start lately, unless jumped from another truck. But if i take the plow batt + wire off then the truck will start no problem. i dont even know where to start looking.

    I suggest you start with the power wire, look for shorts, bare wires, heavy corrosion.
