Slowslinger,
Can you state the model# of your Pertronix unit? My recollection was that the original "Ignitor" (still being sold) normally requires a ballast. If the better "Ignitor II" or "Ignitor II", no ballast is needed. II is equivalent to a GM HEI module, and III adds multi-spark. If you do have the "Ignitor" and it says to remove the ballast, I have been telling people wrong for some time.
