CUDA DIED...NO SPARK to PLUGS !!

STILL no spark at all...........

I had a new coil on the shelf, put it in, and no difference.........

What about that ballast resistor.......Can it cause a complete loss of spark?

What else other than my "blue box" could be the problem ??

Ignition switch ? (not sure about these old ones.......works fine for cranking and what not......)

Resistor ? Coil Condenser ? Blue Box ?
