by the CT will be modest, certainly not the 90 volts and upwards required to
"strike" a neon.

best way to test inductance coils is with some sort of current ramping low
amps probe. this will show the current usage pattern which can be compared to
known good waveforms for similar types of coils. snap-on and sevral other
companys make low amp probes for testing ignition coils,injectors coils etc etc
etc. you will not however see turn to turn shorts etc without a low amps
probe and using a ohm meter is just about worthless. if you want to see if the
coil is charging discharging put it into a circuit where it would operate and
watcht the trace of the charge and inductive kick back state to see if it
actually works.
