Took the aluminum cover off the relay and then plugged it back in. (Nathan I saw your post after disassembly) Now you could see the relay triggering to power the CDI with the ignition off. There is a small circuit board controlling the relay….a capacitor, transistor, resistor and a couple of diodes. Now I had help from my father who is the electronics guy….all the components checked out with the exception of the transistor. The collector/emitter junction was not crisp on the tracker scope like a new transistor would be. So he replaced the transistor and the delay relay is back in the car and working with ~3.5 second delay for ignition shutdown.

My father bench tested the relay as it came out of the car and the delay was variable 6 seconds, 8 seconds, 20 up to 30 and then also staying on. The latter is what happened to cause me to hear the CDI being energized at rest with the ignition off.
