It's probably more likely that the voltage spike is feedback from the coil's high tension output and due to a poor grounding scheme.



Part of a recent wiring project on my part was a redoux of the frame, engine, and harness grounding.
Motor mounts and the two rear fender bolts under the seat got involved in the process.
But, I had never done anything about the sloppy coil primary connections 'till recently.
I'm currently fighting a miss that I'm almost certain is fuel related, but thought I should take the coils out of the question before proceeding further.
As it turned out, one of the terminals was slid back like it had been moving around on there.
Any of us can certainly come up with their own plan on this, but I'll relate what I did.

Pull the coils off their mounts.
Disconnect and grease terminals.
Give the connector shells a little squeeze with ignition pliers or equivalent.
Reattach and remount.
Terminals should go on kinda hard.
The reason for pulling the coils down is so you can get behind the terminals and make sure they're on all the way.
Absent this step, they may just slide back in the shell as it is pushed on.

Now the relevance to this thread:
Is it possible that intermittent coil primary connections could contribute to ignitoer failure?
I've lost two of 'em.
