I don’t have a charging circuit schematic, does any else? The wiring has been all hacked up. Four splices within 6 inches of the alternator. There are three wires in the loom. One labeled “tach” is chopped off. One labeled “ign to reg” goes to pin 1 of connector. One labeled “alt output” (I think) goes to pin two of the connector. I assume that the “ign to reg” comes from the key switch? Is the “alt output” the sense wire? What is the tach wire for?
