Pertronix---

So----I got my Pertronix kit and studying it I am trying to determine the location to tap the red wire into the ignition side of the ballast resistor. I used my meter to find the ignition switch side of the resistor (2 wires on a plug) but I am unsure where to tap the system. The schematic shows the unregulated power entering the coil of the ignitor (red wire) and the output from the ignitor (black wire) going to the coil. The puzzler for me is the fact that the wire from the low voltage side of the ballast resistor still connects to the coil and I cannot figure out why. Any insight would be appreciated!!!!!!
TIA, Rat

The ignitor works best if fed a full 12 volts to power its own switching circuits, and it's OK to splice the wiring anywhere on the ignition switch side of the resistor. The coil itself doesn't get the full 12 volts; it still needs the ballast resistor to regulate its power.
