thank You John G
I see the issue with the magnets and there potential for failure, either from heat, to large of an air gap or just plain poor quality control. The more I learn the more I want to know.


The reason I asked about Pertronix ignitor 1168LS is that it does not use magnets in a plastic ring. whats in the photo is what you get and none of the instalation videos show a ring.

Im not sure I fully understand the Hall effect, So Im probably wrong. But it apears to me that the 1168LS uses the lobes on the disteibutor as the trigger.

I did see though that a lot of the pertronix kits use the ring, just not this one.
