computer control through ERC, I suddenly found that one of them  (a 
G-1000DXA) was turning much more slowly counter-clockwise than  
clockwise.

path between the direction potentiometer and the  controller, and that 
the plugging/unplugging wiped off some oxidation inside  one of the Molex 
plug/jack combinations on the back of the controller. I've  seen 
something similar in the past with the Jones plugs at my entry panel,  
where a little CAIG conductivity juice made all the difference in  
restoring normal operation.
 
    The Hy-Gain rotators are also subject to problems  related to voltage 
drop. That's why the manufacturers want you to use good sized  wires.
