stuck odometer, type 44, infamous gear is intact

[kbogach]

Hi everyone,
I got sick of stuck odometer in my UrS4'93.  I said type 44, I know, but 
instrument cluster is virtually the same as in my 200tqa.  At least, 
odometer/speedo part.  First thing I did is  searching  digests I stored 
unread for the last 2 years (unfortunately, I am still that crazy busy 
and I am lucky that both cars do not give me big problems for the last 3 
years. Except broken clutch pedal, but it was on another 200tq which I 
lost to divorce.   By the way, it was foolishly "got rid of" for $500 to 
some lucky guy).
So, I found out that Huw dealt with the similar problem in January 
2007,  a little after I replaced that  15 tooth gear, which was 
completely fine, by the way, with one I bought from Southern Electronics 
(I posted a question and got a pointer right away.  Thanks again!)    
Did not help.   Odometer  was still  intermittent.  Taking it apart 2 
more times and trying to figure out a cause did not do any good.  I 
lived with it until today.   By the way,  I seems to me, it works better 
at colder temps.  Bug rather than planning to move to colder state I 
decided to poke into the odometer again.

I've never heard about similar scenario on these clusters(I spent some 
time searching through archives before).   All posts about the stuck 
odometer concluded with broken gear. But just in case,  anyone can think 
of something?  I am planning, if I don't find anything mechanical, to 
solder 2 thin wires to odometer's motor, lead them outside and solder a 
LED to them to exclude electrical problem.  Unfortunately,  I don't have 
a pulse generator to test it on a bench.
