Good morning, my name is ***** ***** am I speaking with?

I would need to know exactly which ignition system you have. Do you know the name of it? If not, can you snap a few pictures of it for me.

It is a Pertronix setup, got it.

What does the voltage read on the purple wire on the coil with the key on engine off. And the also with the engine cranking over?
