That's weird - mine died Sunday morning as well. Made for a lot of running
to the back door to check beam headings.

I have a replacement pot at least.

Good Luck

Try running the rotor through it's entire rotation back and forth several

1996 or earlier and this works for me.

Subject: [YCCC] TIC Ring Potentiometer Failure?


Hi all,


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
search
of the towertalk archives shows that there have been problems like this in
the
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
with
contact cleaner from the outside. That did nothing, but I suspect I would
have
to disassemble the motor to get the spray into the right places.

Any suggestions?

Thanks,
