Sc clock repair

I have a 1980 sc with a non functional clock. Removed,disassembled, and replaced capacitors as per some of the threads in this forum. Mechanism is spotless. Motor does not move, gear train appears to be perfect. Reflowed all soldered joints. Coil tests good continuity and small wires connecting it to circuit board are good. Any ideas?

Have you made sure there is power from the car going to the clock?

Paul' Speedometer shop in Redondo Beach-Used them for decades-Top notch.

Usually, it's the two large capacitors.

Do a search-Clock Repair and save yourself some $$$$$$.

Good luck,

Gerry
