86 SPG - while driving yesterday afternoon I had a sudden loss of power, all electrics were on, but the engine had stopped. Turns out the ignition coil wire had popped off, however, as I was about to reconnect it I noticed it was partially melted and the contact inside was scorched. The coil itself looked normal but something caused the wire end to pop.
I had an aftermarket coil in there that I put in while troubleshooting a different issue last fall but still have the original coil that still tests correct according to the Bentley and if I remember right the aftermarket coil fell outside the normal resistance ratings when tested new. I got a ride home, grabbed the old coil, installed it on the roadside and the car started and ran fine on the way home.
Does anyone think the cheap coil could have overheated more easily and caused this, or because the coil wire was so scorched and popped off so suddenly that there could be a different more serious issue afoot?
