Reply to "Pertronics install"

Sorry John, my mistake, I saw the light blue on the one wire attached to the coil and I thought I was looking at a late model engine bay.

Your early car does not employ a resistance wire in the ignition circuit. It uses a "dual" ballast resistor.

That's the convoluted thing about the early cars, that dual resistor module, one resistor is in line with the power from the ignition switch to the positive terminal of the coil (note the "red" wire is the power from the ignition switch). The other resistor is in line with the wiring between the negative terminal of the coil and the points. I have no idea why the resistance was split up like that.

Remove the red wire from the resistor (its actually a pink wire that has darkened from the engine compartment heat) and connect it to your new relay. Unless you plan on using this resistor for something, remove it and file it in the round file.

The blue wire with black stripe that threw me off earlier, thats the wire going to the tach, you'll need to reattach it to your new coil's negative terminal, unless you're installing a multi-spark ignition.

Your friend on the DIC
