                   ...........Usually it's just the
solder that melts in these clock elements, breaking
the circuit continuity and stopping your clock. If that
is the case, it's as simple as re-soldering the 
connection. Just make sure you use a solder with the
proper "melting point" as this solder is essentially a
fuse, meant to melt when the "element" gets too hot.
It's getting too hot is usually caused by the oil in
the gears gumming up with age, or corrosion on the
clock shafts. I've rebuilt 3 or 4 of these now and
usually it's just the oil gumming up. Use some good
quality electrical contact cleaner and thoroughly
soak the whole gearworks a few times. Then re-oil it
using oil specificaly designed for clock gears. I've
used sewing machine oil and 3in1 oil with good results
as well and it's far easier to find. Others here
may have a better recommendation as to what oil to
use. You can often get by using the original solder
that is left over on the connections. There is often 
still enough there to get the job done. Once you're
done with that, it's also a wise idea to, with some 
fine grit sandpaper or emery cloth (220 grit) clean
the two contact points in the electric "element" and
them rinse it off with some more of the electrical
contact cleaner. Just make sure you don't get any
contact cleaner on the freshly oiled gears, or it
will wash away your oil. Hope this helps.
