Trouble with pertronix ignition

Is it possible that you or someone has left the key "on" sometimes? "Back in the 70's" I had a cousin with a Jeep/ electronic. He had been through several boxes, and it turns out he did not realize you cannot listen to the radio with the key "in run"

I believe that is only an issue with the original Pertronix. One of the improvements in the II version was to have a timer on the switch so it would not act like points in the closed position with the key on.
