I had another go at the clock today. Since it did tick, it
seemed that might be working, but a mechanical problem could
be causing a problem. Took the clock out and cleaned the internals
as best I could and lubricated the movement with silicon spray.
It works! During the repair, I found that my outside temperature
display is broken and had been covered up with a piece of
electrical tape. Another minor repair to do someday.

Regarding the new capacitors, they are installed in the clock
in series. That is, the negative pin goes to the positive
of the other. This has the effect of halving the capacitance.
I don't know why VDO didn't just install a half valued capacitor.
I just mention this to help people, (like me),
who might doubt their installation.
