Try running the rotor through it's entire rotation back and forth several
times. I have this problem from time to time with a 1022 as far back as
1996 or earlier and this works for me.

Subject: [YCCC] TIC Ring Potentiometer Failure?
Not far into the contest this weekend, we began to have trouble with the TIC
1022E [a 2003 unit]. It exhibits erratic readout and rotation behavior. The
load is an Optibeam 4-el 40m yagi. I recently tightened the drive motor to
eliminate slippage of the ring gear. I suspect something has happened to the
potentiometer that feeds back rotor position back to the controller. A
of the towertalk archives shows that there have been problems like this in
past [1996/1997]. I went up the tower to have a look this afternoon, but did
not see enything suspicious. There were no bad external wiring connections,
etc. I sprayed the drive shaft and what looks like the position pot shaft
contact cleaner from the outside. That did nothing, but I suspect I would
to disassemble the motor to get the spray into the right places.
