Check to see that the offset value is correct. Use the GH config program.
(You can do it from the front panel but I forget how.) I suspect somehow
you set the offset value to 90 degrees. I have done it inadvertently. If
the pot is bad it is unlikely to be off by exactly (or close to) 90
degrees consistently. I had a T2X pot get zapped in one area by lightning
and the display would wander in value when the rotator was pointing in the
direction of the zapped part of the pot (wandering could be anything from
correct to off by +/- 60-70 degrees as I recall).

Is it possible that the pot inside my TailTwister rotor has moved? My
antenna direction on my controller now shows 90 degrees off (to the West)
for some reason. I climbed up the tower and confirmed that the mast has not
slipped in the rotator clamp or at the boom to mast clamp. I checked wiring
connections and all seems to be ok. Did the pot move 90 degrees? Anyone ever
see this before? I would appreciate any advice on this before I go through
the trouble of replacing the rotor with a spare. BTW, I am using a Green
Heron Engineering controller.
