Could someone explain the workings of the c2 clock. When I purchased my 63 the clock was sitting on the floor. I took it apart cleaned it ( kind of ) and lubricated it and cleaned the points. When I open the points all of the way the clock runs until the points close. If I apply 12 volts across the terminals it does not seem to do anything. I just curious how all of this works. Thanks in advance.
The clock is actually driven by a spring motor with a small mainspring. The good news is that you have gotten the mechanical portion of the clock to work so there is hope. The mainspring is wound by a solenoid that is energized about every two minutes or so when those points close and complete the circuit. That rewinds the clock for another 2 minutes and opens the points. You have a lot of corrosion so the next thing to do is file the points with a jewelers or small file (or sandpaper in a pinch but that is the least favorite weapon for this as it tends to leave bits of abrasives embedded in the contacts). An ohmmeter is your friend so that you can check for continuity. If your coil is open then you probably need to send him to a rebuilder but 9 times out of 10 cleaning the points worked for me but I never tacked a broken clock with that much corrosion.
The other thing to check is the small strip which connects the power terminal to the points. In some clocks that connection is made by a soldered wire but most of the later clocks (yours) that connection is made by spring tension and that connect can become corroded as well. Lastly make sure that the internal ground circuit is good as well.
the points on my clock were almost gone on one side. not having a lathe, I repaired the points on my clock with a dab of solder. I then gently filed a flat surface to match the side of the points that was still there. it worked fine.
Not sure if you are working on it for the fun and thrill of doing it yourself, which I get. With that said I just sent my clock to Scott at Corvette clocks and for $315 bucks he sent it back within 2 weeks fully restored and it looks amazing. I converted it to quartz and I'm very happy with it. Just an FYI if you had considered sending it to someone.
