Sorry for the confusion . . . I'll clarify:

The term "coil" was referring to the ignition coil.  I disconnected it so that the engine wouldn't start and I
could have an extended cranking time.  It was the relay that I was feeling for temperature after running quite
a bit more than the rated current through it.
