so.... The ignition works by the sudden discharge of the stored energy in the coil when the transistor shuts off? "Points" is a mechanical switch that opens when it time for the spark plug to fire??

Or the points close to quickly energize the coil then when the points open, and the coil dump it's energy to the plug??? Same difference.

Is it that simple?

Interesting... first time I've thought about this ?!?!?
