   Power up the failing box.

   Using your DVM or other multimeter, on the 200VAC scale - test the box 
at the cable connections for voltages. If there are voltages, do they "do 
things" when you adjust the controls on the box?

   If nothing on the connections, begin tracing the presence of votage from 
where it enters from the mains.  Rotor boxes are fairly uncomplicated 
things - should be pretty easy to find a catastrophic failure like this. 
And, since there has been no fireworks, and you do have some indications 
of 'life' inside it, just might turn out it's something as simple as a 
never-soldered joint that's finally quit, a bad switch deck, etc...  Also 
check the meter itself - did you verify that the it's not actually the 
indicator itself gone bad, and that the box is in fact moving the rotor, 
and just not telling you about it?

  Cheers
