I eyeballed a web page once about a ONBOARD WELDER. It had a Ford Alternator and a little black box with 2 recepticles, a red light, a switch, and about 9 wires coming out of it. I got a Ford alt. given to me, aND PICKED UP A BLACK BOX thingy for $2 at a yard sale(brand new still in package). The only problem is, I don't have a wiring diagram for the Black Box Thingy! Has anyone done this mod, and can anyone furnish me a wiring diagram. The wires are numbered, so just please tell me what goes to what.
