The point is that I installed the switch myself "just in case" the
electronics failed. Not a bad idea especially if you have a non-tech

regularly driving the car.
Thanks for reminding me of times long past.

The "Delta Mark 10" - was the Grand-daddy of all the user installed bolt-on
Capacitor Discharge units. Delta's next model was the "Mark 10 B". That unit
had a little button on the side of it that defeated the CD and returned the
car to a regular points-style ignition. There were dozens of DIY systems
available, such was the state of points-type ignition in the 1960's. Chrysler made
the first big move to electronics, then GM and Ford in the early 70's. One of
the problems with using points to trigger a Capacitor, was that the current
going across the points was very small. One of the "features" of those
systems was the points would last forever because no arcing occurred since the
current was low. But the least amount of dirt or other crud on the points and you
were stuck. With the normal current of a standard ignition systems, crud
would be blown off the points, and/or the current would jump around it. Most
Corvair distributors have enough oil and stuff blowing around inside them -
especially after 40 years. I have opened up distributors and wondered how the
heck the motor even ran! - Seth Emerson
