Just want to give you some experience I have had with Pertronix 1, ran points on our 16 twinport splitscreen with no issues, then swapped to a Pertonix 1 module, I have to say I was really happy as there was a noticeable improvement on starting and running, however about 8 months after the fit I started to get intermittent running problems, felt like off on a cylinder or bad petrol, checked everything except the Pertonix 1 as the general feeling was it either worked or did not. Finally out at a car show on the way home the van stopped would not start and we had to take the ride of shame home with the AA the driver had checked everything and it was clear there was no spark. Got home and refitted the old dizzy with points van started and ran fine, put the Pertonix 1 back in and no spark so fault found. So ran points for a while and then picked up a new Pertonix Dizzy 1 fitted it and have been running it for the past 2 year no issue until this week, again had the van out and had a loss of power just managed to nurse her home I think on 2 cylinders. So rather than mess around swapped the dizzy back out to known good one with another Pertonix module and all good again. So what’s my feelings on electronic, maybe I have been unlucky but yes electronic can give intermittent issues rather than just stopping. I like electronic as the van did run better but Im now thinking of going back to points. I wonder if any one else has had similar issues with electric ignition. I did carry a preset points dizzy with me just incase. Failing electronic is a big hit money wise compaired to a set of points.
