Its getting replaced.
How the engine still runs on it blows my mind.
Question is what happened?.

Question is what happened?.
The car has a factory tach, so I am assuming 2 wires for it.Odd, it was unhappy about something.
Why so many wire’s to the bolt on terminals of that coil. I’ve never seen that before either.
The ECU has its own ground wire screwed into the firewall.You said it has been upgraded to electronic ignition. If the CPU is not properly grounded it taxes the coil as well. Both get overheated. Usually the CPU transistor will open up the transistor until it cools down again. That happened to me many years ago when I first upgraded to the orange box. When it shut down I noticed both the coil and CPU were too hot to touch. I would replace the coil and make sure the CPU has less than .05 ohms between the case and neg post on the battery. I bet it is way higher.
I would verify it though with a digital ohm meter. I've seen dedicated ground wires that were not doing their job because of paint or a bad connection. It only takes a second to prove it. We all know the definition of Assume. That is what got me in trouble when I scraped the paint off behind the mounting screw thinking it would be a good ground and it tested at 25 ohms.The ECU has its own ground wire screwed into the firewall.
Possibly the previous owner grounded it after this happened to the coil?
