Re: Coil wiring question

Just a few more points on this 6 volt positive ground Pertronix stuff:
If the subject car is equipped with an overdrive (not the case in this thread) there will likely be two wires attached to the positive coil binding post. One wire goes to the ignition point set, while the other goes to the overdrive kick-down switch. When I contacted Pertronix about how the kick-down functionality could be retained they provided the attached schematic . . . essentially a 7 ohm, 5 watt resistor in series with the kick-down circuit.
If the car is currently AutoLite equipped, and a Pertronix coil is used, then the installer must provide a coil hold-down strap. Seems the Delco equipped cars used a 'bare' coil, just like the Pertronix replacement items, while the AutoLite coil had an integral coil clamp. See group 4.12033 in the parts book, and note the strap is only used on Delco equipped vehicles. Not a big deal to make one out of sheet stock, just be aware that 'some assembly is required' on AutoLite equipped cars.
