I would like to do a 12V conversion on my 1949 SA. It has a magneto ignition system, and a 6V positive ground system for the starter and lights. I plan to use a 1-wire Denso Mini Alternator. I know that I will have to change the light bulbs to 12V, but I am not sure what other changes I will have to make. For example, do I have to switch the wires on the ammeter? Does anyone have a wiring diagram for this conversion? I am assuming the starter can handle 12V for the short period of energization, as my engine starts very easily...one pull of the hand crank when I use it. Any help you guys can offer will be most appreciated. Thanks.
