Quoted from altan:
I'll take it apart and check it out. I'm thinking it might be as simple as the connectors at the bottom because, after slightly touching them, it started freaking out in test mode (opts going on off).
I haven't heard people having to rebuild the female connector (because of cracked wires), but I'm wondering if that's my problem. Or if I need to reflow the connectors on the clock.
Might need to replace the header pins too if they're tarnished.
While it's apart, might want to quiet the gears down with some grease specifically designed for use with plastic--such as Synthetic Polyolefin (PAO) Lubricant/Grease; M-Kote EM-30L; NLGI#1.
Small jars of it can be found on Ebay.
Mine turned out nice and quite.
My sympathies--and good luck.
