RPM 1,246 Report post Posted June 7, 2022 Ya, those clocks are pretty sensitive. Mine wasn't working, so I watched a rebuild vid on you tube and refurbished it. It worked great until I installed it, and watched the minute hand move faster than a second hand, until it didn't. I've thought of getting a quartz unit, as many are happy with them, but mine sits with non moving hands. Quote Share this post Link to post Share on other sites
69RavenConv 305 Report post Posted June 7, 2022 Sometimes a cleaning, lubrication, and/or filing the points can bring them back for a while. There's always the quartz conversion route, too, like RPM mentioned. Otherwise, at least it's right twice a day. Quote Share this post Link to post Share on other sites
Midlife 838 Report post Posted June 7, 2022 I've found the majority of the clock harnesses, as installed in the factory harness, have bad continuity due to the tight turns in the wiring under stress. That could be your problem. Quote Share this post Link to post Share on other sites

All 69 and 70 underdash harnesses, regardless of tach or not, have provisions for clocks. The wiring for 69's are slightly different than the 70 version.

I think I'm going to do a deluxe interior when I get to that point with my car. Quote Share this post Link to post Share on other sites

jerrywmalcolm 21 Report post Posted June 15, 2022 update, took clock apart, after playing with it for a hour or so, I found one broken wire, which I resoldered on, and found that the ground connection has a 2 point connection, 1 for a wirre the other touches the clock housing which acts as a ground for the whole car, whch might not be making a connection so I soldered a wire from that to the housing, and now the clock works fine 4 1 Mach1 Driver, 69RavenConv, RPM and 2 others reacted to this Quote Share this post Link to post Share on other sites

One of the Mustang parts vendors, I believe it was NPD. Glad you got your clock working, hopefully it will continue to run. Mine didn't. Quote Share this post Link to post Share on other sites
