if the condensor was shorted.. it would act like closed points.
if condensor was open.. it would let points arc and burn pretty quick.
you get some that self heal a bit then die out in a few minutes with warmth..e tc. but it's more rare.
run a hot wire to the coil.
clean points and regap.
use that known good coil.
see what you get with just the coil.. forget the dizzy cap..
