So called 12V coils have internal "DC" resistances of 0.6, 1.5 or 3.0 ohms. The 0.6 ohms are used on some super dupper electronic race systems.

The 3.0 ohm coil is OK with points and fine with electronics without a ballast. Used where a starting bypass circuit isn't applicable. I didn't mention inductive reactance in a coil as this meltdown occured at 100% duty cycle.
