Replacing Points with PerTronix Ignition Pickup - Great Hagerty Article

This is a great article for anyone so inclined as to learn about the points system.

For years I sort of half understood how it works, now I have a much better sense of how it all works.

The issue I had with using the pertronix unit was that the dwell was too low and caused misfire issues higher in the rev range. I contacted pertronix who told me the 20 degrees dwell I was seeing was normal, but this is nowhere near enough to saturate the coil at higher rpms. When I swapped the points back in the problem went away.

I modified it and ended up with around 28 degrees dwell before the pickup was losing signal from the magnet, which improved the problem but didn't completely solve the ignition breakdown at higher revs.I know other people seem to use them but I dont know how they work with such low dwell settings and no adjustment unless yo drill out the rivets and move the pickup away from the magnet to increase the dwell.

I ended up tossing the pertronix and went with the Crane XR700 optically triggered setup and havent had an issue since.

Interesting Krizza, good feedback.
