All of the "parts houses" say they have never heard of this and do not have a clue where to get started. They all agree that it is NOT the neutral safety switch.

1966 Convertible- Cruise-O-Matic Transmission - with cruise control. Cruise is not working, nor is it a concern right know.

If the gearshift is moved just the slightest direction, the voltage regulator "clicks" and the lights go out. Headlights, map lights, if the door is open even the "door ajar" light goes out. I can put my finger on the voltage regulator housing and feel it clicking. It does not seem to matter where the gearshift is (L-D1-D2-N-R-P) moving it just slightly causes the click and the lights go out. Wiggling causes the lights to flash on and off.

I have also noticed that the light around the ignition switch flashes on-off as I drive.

Surely, I cannot be the only one that has ever had this problem.
