I suspect that you have a bad reed switch in the rotor.
M2 sells them for $25.
I am pretty sure you can not replace it on the tower, I might be wrong.
Getting the rotor out and down to replace it will be the hard part.
If you do that, I suggest testing it completely on the ground, before
putting it back up.

Subject: [TowerTalk] Orion Rotor Indication Trouble
After a tower rebuild this summer my Orion rotor began giving me
intermittent direction indication readings. The unit will quit turning
normally and will only turn in very small increments and not indicate
direction correctly. When it does come back to life the controller must be
reprogrammed and then it will be fine for awhile only to start the cycle
over again. M2 recommended using shielded cable for the sensor lines so I
used some RG59 for each lead and thought that the problem had been fixed.
Unfortunately this past week the trouble has appeared again. In addition to
the change to shielded cable I have also tried another control box with the
same results. Has anyone else experienced this? Is there a fix?
Thanks,
Jim N0AV
