Reminds me of the old fable about a group of blind men trying to describe an
elephant. Each was feeling a different part of the animal and thus describing a
different creature (I feel sorry for the one by the tail!). At any rate, it has
been 20 years since I worked with LCR circuits, and I probably missed some
techincal points (for which I SHOULD be corrected), but my statement still
stands: The capacitor in your ignition system is designed primarily to provide
a hot spark. Improving the life of the points is definitely important, but is
"icing on the cake". It's amazing how aggressive some people get when they feel
a point is missed, kinda like cyber road rage. Anyway, ask me anything about
PID loop tuning or control systems.....I'm ready!
