I read many posts lately trying to ubderstand coils and ballast resistors. I Have a Farmall H that has 12 V battery, 6 V coil, and a ballast resistor built into the ignition switch. I think switch went bad so got a new 12 V coil and new on/off switch. Coil stamping said "requires external resistor" but nobody knew why (surprise?). Tractor started fine but after 5 minutes of run time, coil was too hot to touch. Back to local parts store and got a 1.8 ohm ballast resistor and installed (fabricated a heat sink). After 10 minutes of run time, coil barely warm. My vote is to use the resistor - even on 12 volt system. Next step now is to debug generator.
