Good morning.
The boots are leaking in the wires. they are worn out and allowing electricity to leak to the well.
Replace the wire set. That will resolve the issue.

I have purchased brand new spark plug wires from places like Walmart or is not an auto-parts store that also shorted to the metal engine. The parts are cheaply made, just going with a brand name is these are new would fix the problem. If they are old, then I agree with Asemaster.
