The radio does the same thing without the engine running. I don't know what a transistor ignition is so I don't know if it has one. The antenna is mounted on the top of the right quarter pannel and has a cable that goes through the fire wall and in to the radio. I tested the voltage to the radio as you suggested and it is getting 12 volts. So far, all I've done is remove the radio and the cover and blew the dust out. The dials and buttons seem to be working. Then I plugged in the speaker, antenna, and power with the engine off and nothing changed.

I really appreciate your input.
