Cap, rotor or wires.
These have caused me trouble before.
I mentioned it in post #2.

I replied having only read page 1.

If you have pos ground and touch a neg jumper to the neg side of the coil it probably won't generate a spark.

You need to have a constant neg feed to the coil and intermittently connect between the pos terminal on the coil and ground. It should generate a spark as you remove the contact with the ground.
