Okay I have a few questions I have come up with while trying to figure out the 6v-12v conversation on my '46 Chevy 2 ton.

#1 I'm installing a 12v alternator, the one I have is a single wire internal regulated model. I was under the impression all I needed was to run a single wire from the alternator to the pos battery terminal. While reading the conversion tips it stated a DA wire is added and the wire goes to the ignition switch. Which would I do?

#2 in the wiring diagram I see a polarity reversing switch in-between the coil and distributor. I didn’t see anything else in-between the coil and distributor, Is this and internal part? Do I need one?


#3 when I replace the 6v coil with the 12v coil I plan on getting and internal resistor model, do I need any type of voltage reducer for the distributor? Or will this act as one? Do I replace something in the distributor to convert it to 12v?

Any help is appreciated.
