Anyone know about the AMC clocks? I took mine out to repair and 2 of the tiny screws that keep the guts intact were off, and so it fell apart a bit as I took it out of the housing. I managed to get it all back together, but I had to rewind the metal coil that keeps tension on the moving point. Both the moving point and the stationary point were dirty/fried ... and flat/concave. When they make contact the clock stops ...I can pull back the tension point and it will move again back towards the stationary point. I figure when power is applied the points will fly apart when they meet, but when I tested it w/ power nothing happened when the points met. What am I missing? My clock is from a '65 Rambler classic

The coil could be burned out.

They're horrible things.  The windup mechanism is a crap design, the spring when new runs it for what, a minute? THe contact closes and CRRRRKKK a big spark sprays a small mist of aerosolized metal throughout the clock housing.  Just great. The spring is short, it fatigues in a few years. ALso the solenoid draws 10 - 20 amps in a brief pulse (average power is very low) so the solenoid heats internally and it does require a solid ground.

They're comically bad designs.

I had a working one in a 62 Ambassador 400. I did my first cross country road trip (Mass. to Bremerton WA, round trip) in it in 1974 when I was 19. I slept in the car. I still remember the tick tick tick tick... get quieter and quieter then.. CLACK TICK TICK TICK tick tick ... as the winder wore down.

My brother does clock repair. I gave him my clock for my 70 AMX. He just did some cleaning and uses a wall wart 12 VDC power supply to run it. It has been running on his bench for 3 months now. Gains about 2 minutes a week. Can't get it to slow any further without major overhaul. I'm good with that. Like he said, they are made to last about 7-8 years...about the normal lifespan of a car out of the '70's. NO, he is not available for repair of car clocks. He is about 18 months out with what is in his shop right now.

Unless you want the car 100% dead nutz stock, the quartz conversion is the way to go.
