Yep, they can go bad seemingly pretty fast. Last summer I had a new Lucas
sport coil go bad. I was driving around and suddenly it had a terrible
misfire. It seemed to be running only on 2 cylinders. I managed to limp it
home for about 6 miles. It died in the driveway. I checked everything but
concluded that the coil must be bad. It was pretty hot to the touch. (No, it
was not the type requiring a ballast resistor, or at least not labelled as
such.)
When I re-installed the 1966 vintage coil, the engine started to run fine.
A fellow club member had a somewhat similar failure except that as soon as the
coil cooled somewhat it started to fire fine. THat made it REALLY hard to
diagnose. Again, it was SCORCHINGLY hot.
