I am in the process of changing to 12 volt neg ground one wire altenator. I have the entire 1929 car set up without body or wiring. I want to start the engine, does anyone have a simple wiring mockup just to start and run the engine. I need to to include the starting wiring and ignition wiring. I am using a 12 volt coil, battery, and just a on/off switch.
 
Run the battery cable to the starter switch. Also connect the alternator output to the starter switch. Run another wire from the starter switch to the OFF-ON switch and from the switch to the coil + terminal. Run the coil - terminal to the points.

Turn on the switch and push the starter switch and the engine should start and charge the 12 volt battery.
