Art,
Can't correct you cause your not wrong. You could find those resistor's on several brands of autos in the 50's as the manufactors changed from 6V to 12V systems, Chevy used one on the "Tri-Five" models (55,56,57) that was a little smaller that what Chrysler used, but the Chrysler type is what is most commonly found/used in after market electrical system changes these days. Guess it took Chrysler longer to go to an internal resistor coil than the others, because I believe they used the resistor longer than the other brands. They all do the same thing, let the vehicle start on 12 V's and then drop the voltage to to the points to 6 V's to keep from burning them up, and the points would burn up in short order if the resistor got damaged, broken, disconnected, or otherwise was defective.
As far as using a 6V starter on a 12V's, it doesn't seem to damage the starter as long as the engine starts on the first few turns, and it will also work the other way. On my Original with the 4 cylinder Teledyne engine, I am using the stock 24V starter, and operate it off of a single 12V Lawn and Garden tractor battery (the highest cranking amp battery I could find), and as long as the battery is fully charged, it will start the engine several times during a weekend show. There is no charging system on the tractor, and the engine has a magneto for ignition power, and normally starts on the first couple of turns. It will take a bit of cranking if it has been sitting for awhile (like between shows) until the fuel pump get's enough fuel to the carb. You can manually operate the fuel pump if it has been awhile since the engine was started, but it is easy to flood the engine when doing so. I got the starter and an alternator off a used engine, and the starter is a Prestolite and the alternator (not used) is a Motorola. You don't suppose someone would have sold Uncle Sam a 12V system and just claimed it was 24V do you????
