Hi All,

I bought a secondhand G5400B and promptly dismantled both rotators to 
overhaul them and also completely repaint inside and out, and they 
now look like new :-).

My question is I set the azimuth rotator as per the instructions and 
all seems good apart from the CCW direction does not indicate 180 
(far left), more like 165-170, is this normal? Mechanically it 
rotates more than 360 but the resistance of the pot is 14 ohms CCW 
and 8 ohms CW. I would have thought it should read 0 CCW then setting 
the adjust pot on the controller to 180 with the rotator exactly 360 
round CW. Hope I haven't lost anyone with this description :-).

Any guidance would be most welcome, thanks.
