I have been building my 1930 Tudor as original 6 volt system. But I find that the 6 volt battery does not have enough power to spin starter fast enough, consistently enough to be reliable start. When starter does turn over with any speed, the car does start and run fine, the generator showing a little charge on amp meter when running. It is a new battery, but battery is too weak to start the next time needed. I feel that I need to convert to 12 Volt system for the extra power to start. What electrical modifications need to be made for conversion?
