Points? As in opening/closing distributor points? It's been a long time
since I've seen a schematic for a CD ignition but to my knowledge they
have been replaced by magnetic type devices.

I just did a Google for "CD Ignitions" and found:
http://students.fct.unl.pt/users/ejr/ignite.html

One sentence in that article reads, "The cure for the Kettering system
is to use the points not as a current-carrying switch but merely as a
signaling device to tell the ignition system when to fire the spark. The
actually switching is done with a solid state device called an SCR
(silicon controlled-rectifier), a specialized form of transistor."

But take time to read the entire article, it's a history of auto
ignition systems and is very interesting.
