Well, I've been trying to retake the dining room table to work on my harness, but no dice. Wife needs to bake homemade cookies. I have my priorities!
So, until I get room again, I thought I would turn to the instrument cluster. I reread BigKev's blog on his clock repair (page 89) and I began to attempt to do mine. Even though the face of his is different, the inner parts are very similar, if not the same.
Removed the small screw on the top of the adjuster knob with a knife and pulled off the knob. Removed the mounting screws from the back and moved the electrical connector box out of the way (not sure what it is called).
I tried to pull the clock out, but the housing in the front that the adjuster knob stem goes through needed to come out. I pulled it out and tried to turn it thinking it was a screw. No go. Kept messing around with it for about a 1/2 hour before it finally came off. Looks like it was just pushed on after all and only needs to be pulled off! Pics of it below to help anyone out in the future.
Once the clock was removed, I wound it by moving the weights. The clock would not work. Then I took a trip out to the garage and sprayed the crap out of it with PB Blaster. I let it soak for a minute and then spun the wheel on the gears (goes back and forth when the clock is running) and the clock started to work! It ran for about 10 seconds and stopped. I spun the wheel and put pressure on moving the weights (the direction they would go as the clock unwound in use) and the clock kept going. I took pressure off the weights and the clock now runs on it's own! Cool!
After that, I cleaned the contacts with a file and verified that they opened when the weights wound the clock and closed when the clock was unwound. I did not connect any power to test it. Not really sure how I can do that. I may just "assume" it is fixed and know for sure when I reinstall it in the car with the new harness.
