I am getting no spark on my tester from the plug wire that goes to the spark plug.
I am getting no spark directly off of the cap.

I AM GETTING spark off of the coil wire.

This says the coil, green wire and ignition module is good due to the fact that the coil is firing on my tester.

It points to the cap or rotor not passing the voltage, I have a new cap and rotor coming from Roger.

Zeus has been coaching me on this and feels that's the issue. Has anyone been through this?
