I see, interesting. Maybe Pertronix know there are some issues and why they exchanged that P3 without question.
I will be looking into this. Its just that I had gone out and purchased two P2's thinking it was an easy bolt in upgrade similar to the P1... My original P1 worked fine until we were trying to adjust the QJet carb. We had spent an afternoon in the garage starting and stoppin the engine and probably left the key on for too long and burned it out... I will also look to run the 12v power line to the coil for future use.... I have 10 spare sets of points..., so I'm ok ))
You probably won't want to do this, but as I just remembered what I had done so I could run points on a resister in the event of an emergency while out on the road. This was back when I had the P3 on the car and I was having timing issues, I installed a Chrysler type resistor (I forget what Ohms it was) on the firewall. Again trying to recall, I think I took a 12V supply from a different switched source the ran a separate wire to the coil. This wire was wrapped up with the other wires going to the coil and temp sensors and left disconnected of course, but here if needed. The only thing was I didn't hide the resistor, but it could be done. This didn't last long however once I gained confidence in the P2 and I removed it.
