As pointed out, the ballast resistor is to limit the current through the coil to an appropriate level. In automotive applications before electronic ignitions were common, the starting circuit would bypass the ballast resistor to provide a hotter spark for starting, then switch it back in when the engine was running to keep from burning up the points. New coils designed to run directly on 12 volts are available, although I don't think there's any real advantage to using one. You can still only pass so much current though the points without burning them up. Keith
