OK, enough politics and soapboxing about jmw's post. Time for a simple mechanical question. I'm about to install a Petronix ignitor in my 71. The hot wire to the coil is a resistor wire which drops voltage to about 9 volts. This much we know. When I install the ignitor, do I use this same wire or do I need to run another wire to supply 12 volts to the coil?
