1. Since you use a floor stomp starter, and an ON/OFF ignition switch, there is no means of bypassing during cranking, 2. Not sure why they thought it necessary to add the extra voltage to the points during cranking.
Remark 1. The ballast is "bypassed" in the sense that there is an alternate path during cranking. The wire from the stomp switch side terminal is a direct 12V to coil. The wire from resistor is not full 12V. So while foot on switch, full 12V is applied to coil. I guess AD's don't have stomp switch side terminal? If not, then I guess it was improved in TF to provide direct voltage, as I explained below and by HRL, as they went from 6V to 12V.
Remark 2. There is no "extra Voltage" added to points really. It's that the starter pulls so much that reducing the voltage through the ballast, if there was no other source (direct from stomp) the spark would be reduced when needed to start a cold, dry motor.
