Ham-II Rotor Anomaly

The Ham-II (I think it might be....Ham-something, anyway) on our club
station (W5RRR) 80' tower does a complete 360 degree rotation as is 
normal, but, the meter stops as it stops at about 250 degrees.  I 
measured wiper to pot arm voltage and it ranges from 2.55 volts (meter 
reads 250 degrees) to 12.85 volts (due south through East).  The limit 
switches do their thing at the appropriate times.  

My guess (since it has been too cold and wet to climb this week) is that the 
wiper arm has somehow jumped out of its nook in the bell housing or the pot 
element has strangely gone bad somehow.  

Any ideas? 

Post to me directly.  I will summarize to the reflector.

Thanks and 73,

Dale Martin, KG5U
