After exciting the ignition with signal generator, spark breakout was visually noted to be about an inch from the ignition in the HT lead. Opening the shield and inspecting, the center conductor has a horse shoe bend of about 1/8" hump and placing it thus very close to the braided shield where it ruptured through the dialectic.

Who knows why it exist, shrinkage of the dialectic, manufacturing anomaly, or perhaps installation to the ignition error, by soldering the conductor within the ignition and then forcing the dialectic and braided shield into the housing crimp and thus compressing the center conductor causing it to buckle into the horse shoe.

I will try some kind of repair but am unsure of success.
