So I decided to try a new Accel module in my ignition amp on my 88 XJS. Removed working GM one, cleaned off old grease, put in new one.
Drove 2 miles, and it stalled. Waited 15 secs and it started and drove about 100 yards, and then stalled again. Managed to get it home after four restarts.
Took it apart, I’m an idiot, FORGOT to put thermal paste on! Did I fry it?
