The conventional points dizzy works off a coil that is designed for full output at ~10V to facilitate easier starting when the voltage drops due to the battery working the starter.
Obviously when the motor is running 14V is seen across the battery and this would fry a coil designed to give full output at 10V.
A resistance(small length of resistive wire) is placed in series with the coil when the ign is in the run position to reduce the voltage across the coil to 10V.
This wire is bypassed when you put the switch in the start position.
Electronic ignitions apparently dont suffer as much when the voltage is reduced at start up so they have a coil designed for full output at 14V and no resistance wire in the run position is necessary.
So part of rewiring for a 12 V ignition is bypassing the resistance wire and increasing the current rating of the circuit due to the higher energy of the system.
