Re: 6 Volt to 12 Volt Conversion for 1939 Super 8

As said above why go to 12 volts. Looks like you will have enough to do in regular restoration. So it cranks a bit slow when starting. Only problem with 6 volt is if the car has been sitting awhile, it is better to have an electric fuel pump or just before cold starting put a bit of gasoline into the carburetor. Once warmed up will start fine. I use 6 volt Optima batteries and have an old tungar charger if needed to keep them charged. For a modern hidden radio you can get a converter. It actually sounds and looks great as the 6 volt system slowly cranks a large 8 or 12 cylinder up to speed to start, kind of like an old prop airplane.
