David,

If you have a 6AL, there is not 12v at the ignition coil, there is some 480v with the engine running, since you have a CD ignition, not inductive ignition.

The coil primary terminals are more dangerous in a CD ignition.

After reading your opening statement, I wasn't surprised to see you have a MSD ignition fault.

Now, onto some testing.

Can you disconnect your mag trigger harness at the distributor, remove the coil wire from the distributor, set up the coil wire with 1/2 inch gap to ground.

Get yourself a paperclip, form a horseshoe.

Then ignition key on, bridge the mag harness that goes towards the 6AL module in rapid on/offs. Does spark jump across your 1/2 gap?
