Points and early coils were designed for 6 volts. When cars switched to 12 volts, they just added a resistor (either inside the coil or external) and called it good to keep the points from burning out sooner or the coil from overheating. I discovered long ago that a Mopar electronic ignition coil (mid '70s) on external resisted points system worked awesome! It pumped up the peak output voltage and cold starts were a breeze in my '73 J4000. From: "Daniel G.
