[TowerTalk] Yaesu G-450A troubles

[KI9A at aol.com]

gang-
 
I have a 2 year old 450A rotor, that seems to have issues with the  
indicator. Starting from due south, and moving clockwise, the 1st 90 is smooth  & 
accuate, then it begins to studder, and miss. It stops at due east, but  the rotor 
itself is over rotated all way over to due west, which is normal. I  watched 
the rotor turn, it is smooth, no problems. Seems that while watching the  
indicator motor drive the gears, the motor is studdering...but, is it the motor,  
or a dirty pot in the rotor? Anyone ever deal with the these??
 
thanks & 73-Chuck KI9A
