I still haven't seen any in-depth explanation of the ballast resistor, coil, and electrical system. just saying to google positive ground system and such is not the answer. It is too general. We need a definitive Ford 6V/POS GRN System stated in both front mount and side mount terminology.
Also, FWIW, does anyone else see anything wrong with this diagram? Look at the upper LH exploded view.
