Check R2 10k resistor and the 5k pot in the controller. Sometimes these
get changed out to make meter indication right for some other application.
Like a rotating tower or an elevation rotator.

I'm going through my rotor collection getting ready to sell them and found
an issue with two of the control boxes.? Using a good T2X as the rotor I
got normal operation and indication from several control boxes.? However,
two other control boxes did not operate as they should.? Both boxes operate
normally except indication is off.? One has indication stopping at 90
degrees even with the calibrate turned full clockwise.? The other does not
indicate the other way past 270 degrees even with the calibrate turned full
counter-clockwise.? Both however, do rotate the rotator 360 degrees.
I know the rotator is indicating OK since it indicates perfectly with three
other control boxes.? Any ideas as to what is going on?? My first thought
is the calibrate pot is bad, but I'm not sure.?
