Has anyone heard of a coil exploding?What would cause it? What do I look for to trouble shoot?

I have had more than one coil fail on bikes, boats and cars. None were caused by anything. Once I replaced the coil, all was well. I have borrowed a coil in the past off a tow vehicle at the lake to replace a coil on a boat, then swapped back for the trip home.

Had it happen with 2 coils that were bad out of the box or very shortly after.

For me it was always a degrading performance and increasingly harder to start as symptoms.
