I had the same problem (without the bad connector, but do have a sport coil
as well as an Allison ignition) on my GT6 - Went through many bad rotors
and fairly quickly, till I finally found the problem -

(installed @ VTR) fail on his TR4A. Failure itself was invisible, a carbon
track through the interior of the rotor, grounding the spark to the dizzy
