I wasn’t going to say anything, but since you started it, DITTO. Points triggering an MSD box. I’ve been doing it for decades. Simple, clean, reliable, and the points last virtually forever with this set-up. And if the box goes puke ( which hardly EVER happens, it’s always the triggering decide that barfs) you move two wires and you are back in business.
I used points to trigger my old MSD Blaster box for over 20 years. The very low voltage also made them last forever. I also have them, along with the conventional ignition system, in my Galaxie, and it starts easier than any vehicle I have ever seen. However, having said that, points don't cut it once you get to 6000 RPMs. In todays engines that will run 6500-7500+ RPMs, you need a better alternative.
Wire breakage is the only factor "I" have seen in magnetic pickup failure in the 40+ years I have been using them.

I'm not the only one who has had issues with a pickup that "checked" good with a basic resistance test. I won't go into details, but most on here might recall that I've double, triple and quadruple checked every component in my system, including using multiple backups on boxes, direct wiring to battery, isolated wiring etc etc etc. My current pickup checks good, but it's showing the same signs of imminent failure that the others have done. My first one lasted about 20 years, but that has all changed since the buyout.
