I'd start with getting the correct coil for the Pertronix unit, the factory coil may not have the proper ohm/turn ratio to support the HallCell in the Pertronix unit, personally I always run the Pertronix epoxy filled coils... if your still running the ballast resistor, your defeating the purpose of the Pertronix system...

I just ordered the Petronix coil, I'll get in a few days, the guy who helped me install the system originally did gut the ballast and soldered in a solid wire to retain the stock look. I sure hope this procedure he did is a proper solution
