I've got a 1947 H with the four position square sort of light switch. It has a GM alt. conversion done to it already with the 3 wire alt. neg. ground. Also has a distributor. When wired it was wired with a ballast resistor, and a small in line resistor in the alternator small wire, a toggle switch for power on/off, going to a push button starter button to a Ford type starter relay and so on. I'm putting a pair of plain two wire single bulb halogen driving lights on it for headlights, and simialar worklights on the rear but not halogen. There is no light wiring on it currently and had none of the original wiring in it to help. I've looked at Bob M's diagrams and my manuals and been looking everywhere but unable to find anything to tell me what my light box should be wired like. All I can find is the wiring for the generator pos. ground stuff but no help. What I would like to know is first of all what the four positions on the light switch are for. Assuming the far left position is off the next position or #2 right would be lo beam next right or #3 would be hi beam/ and next or #4 is ? The wiring to the ammater appears to be correct as the alternator is charging and starting system working well. Ammeter only reads to + or - 20 amps so alt. buries the needle 99% of the time. Do I need to install a higher amperage gauge? But with the issue at hand also I have only the wiring to the ammeter in the box. I need to know where to install my headlight and rear work light wires from the engine end to the box. The diagrams tell my for example the F terminal on the generator. Well no generator and no clue where that would be now. I have no clue what any of the original wires ever looked like, started from or where they went to. This conversion from 6V pos. ground appears to be a very fine and complete job. All connections were soldered wires heat shrinked and wrapped in loom taped and or zip tied and done very professionally. All the equiptment is new/ such as the battery cables. lugs, battery terminals/ wiring even the screws and lock washers on the light switch are new and protected with dielectric grease. An extremely good job but now the lights. Please shed some light on my low light situation. I'm stuck and haven't even attempted go anywhere yet!
