I know exactly what you are saying! I installed Pertronix on my 1970 Impala that I owned several years ago and it lasted one week! The Pertronix quit leaving us stranded at an intersection on a major boulevard, lead car at the stop light, on a Friday night at 5:00 and the traffic behind us was horrible! With horns honking and cars passing we had to push the car through the intersection to a parking lot at a local business.
The point system is just about fool proof and easy to fix if there is a problem, which is rare. I will never, ever use a Pertronix again!
