The Stovebolt Site Forums The Parking Lot '60-'66 Trucks Ignition problems- 305E V6

You forgot to answer about the part number 36-2945.

1. As a point of info: On a 66 GMC there was one wire from ignition "on" terminal to starter "R" terminal. This was the resistance wire. Then there was a yellow wire from the "R" terminal on the starter to coil positive.

2. The Ignitor II instructions I have say that you can remove resistance wire or not. Do you agree? I.E. Figure 2.

3. Here is the disturbing part and may be your problem, once I am sure what you said. Regarding the positive terminal on the coil: you said you have the Pertronix wire (probably red), a yellow wire, and the "resistance wire" on that terminal. That would be three wires. Is that what you have or not? Here are your words:

I followed Pertronix directions exactly, their leads from unit come to ground and positive posts on coil, and the yellow wire and resistance wire are also on positive post for coil. inside distributor there is a ground to plate, and the unit itself.

Very glad you are NOT doing ANYTHING until I am done with troubleshooting.
