A few days ago the right turn indicator in the cluster went out. I removed the clock to get to the socket to remove the bulb. I got it out but could not manage to replace it, so I put the socket back without the bulb. Will remove the cluster in the fall. I reinstalled the clock. Later while returning home one NIGHT I noticed that the clock (quartz replacement) had stopped working. However when I turned the headlights off the clock started again. Each time that I turn the parking lamps or the headlights on the clock stops and restarts when the switch is turned off?????
Took the electrical connection apart again, put it back to-gather and its working fine. Must have been a lose conection at the clock. Still don"t understand why turning the lights on and off would stop and start the clock

It sounds very much like you have a poor or open ground-chassis connection to the body or shell of the clock. I am guessing that when the lights are off the clock electronics are being grounded via the clocks lamp filament. When the lights are on the clock body will be pulled up by its lamps filament to something in the order of 10-12 volts. With a 12 volt supply and a near 12v ground the clock effectively has no voltage supply hence the no go.

That was a pretty slick analysis if I do say so myself.
