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.

Is it grounded?

Good point! Always look for the simplest cause first!

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.

I second the idea of the quartz conversion. Just the case, face and hands are kept so no worries about any lost or worn original parts.

It would be cool to add a sound module that made the right sounds, and also a switch to make it run fast two minutes a week, you know, to get that OEM feeelz going.

(Technology-wise, it would be easy to do!)

I was able to successfully repair my little clock. I replaced the points with some contacts salvaged from an old pinball game. The coil is good though it looks a little dark and I might rewind it.. I carefully cut the salvage relay leaf and popped the contact out. I drilled the old one out of the clock and carefully dremmeled the new one until it popped into the old hole then I swaged it over with a punch. I think I'll add a snubber capacitor to keep the spark down.

Bought a clock from Galvin's and it intermittently worked.
Found a clock resto shop nearby and the guy lightly oiled
it and bent back a couple of metal areas that shouldn't have
been bent. Instead of letting it run 24/7, I installed a battery
cut-off switch and when the car's in the garage, the clock
doesn't run, thereby extending its longevity.  Works for me!

Thanks, Matt! I like the sound of a ticking, re-setting clock, too!
I had my AMX clock restored 35 years ago....put a 1 amp fuse in the line, as the rebuilder suggested (to prevent coil from burning out if points stuck), and it still works fine!

AMC used Borg for a long time: All the 68-70 AMX/Javelin clocks and 61-63 American clocks, that I know best, are Borg.

I had two 68-70 clocks restored this summer for a reasonable fee. One is going to be my brother's retirement gift (he'll have "time" on his hands to enjoy his '69 AMX). The other is my back up clock.
Then I have an NOS Hornet clock to put in my '74 California Hatchback X. (My 'forever' 74 has a factory tach, so no room for the clock!)

Stay well!

Paul

FSJ's post was excellent! Can it be made a sticky somewhere? I would hate to see it lost in the bowels of the forum database.

Does he know a moderator who could do this? Wink

You probably sent that clock to my former professor who taught me that trick in the first place. He restores old car clocks and radios on the side as a hobby. He is a truly remarkable man. He was an engineer at North American Aviation in the 1960's and played a pretty significant role in developing the Apollo spacecraft command module. Many students tried to get on his good side by buying him a bottle of Glenfiddich.

You are all welcome. Happy to help.

Sent mine to Instrument Services Inc and they told me 6-8 wks for the conversion to quartz. Will let you know how it turns out.

I converted mine myself. Bought the kit from Instrument Services and took a few hours to disassemble, install, and test. I also learned that an orange paint pen is remarkably close to the original color of the hands on my clock.
