[TowerTalk] Yaesu G-450A rotor troubles

[KI9A at aol.com]

Gang-
 
I am on my 2nd Yaesu 450a rotor, in the past 4 years. The rotor is fine,  the 
control box has issues. Here is what I see:
 
Indicator seems to work fine, going from due south, clockwise, until it  gets 
about 300 degrees. then it seems to stumble, and, stops at 90 degrees  east.  
The rotor rotates the whole 360.  The problem isn't  with the rotor, as I 
have 2 rotors, and both act the exact same.
 
Could it be the pot in the box, or the little motor that drives the  
indicator needle?  I would guess I'm not the only one who has had this  issue, any 
comments, or ideas?
 
Thanks
