I had the exact same symptoms several years ago, and could visually see
the mast section to the top of the rotator was off-vertical, and
then found two of the three bolts that hold the rotator were gone
and the it was barely held by the third. I had failed to do any
hands-on maintenance on the antenna system for several years prior,
now I have an annual check. My rotator was an Orion, but the
same exposure exists, I think.

Subject: Re: [TowerTalk] T2X Sticking
Is this happening with the rotator at or near the end stop (S normally,
could be N)? Or does it happen with the rotator in any position?

Hello,
What can be causing my T2X to stop turning after a high wind gust?
Have a T2X that won't turn after experiencing a strong, more than 30 MPH,
wind. Then a day or two later the wind has subsided and the T2X starts to
turn. For example, on Saturday gusts were up to 45 MPH. The T2X stopped
turning after the high winds subsided (didn't try to turn the T2X in the
high wind). On Friday, the T2X did turn okay (low winds
- 10 MPH max.).
Sunday evening with calm conditions, wind 10 MPH max., the T2X turned okay.
This no turn scenario has happened other times.
Do not try to turn the T2X when the wind is strong. When do try to turn the
T2X, release the brake, try to turn it CCW and the CW. Neither direction
works until after a day or two of relatively quiet winds.
The T2X is at 120 ft on the tower and approx. another75 feet to the shack.
Use 12 gauge wire for supplying power to release the solenoid in the T2X and
14 gauge for motor and sensor. The phase reversal capacitor is located at
the rotor. The solenoid voltage out of the controller is as expected (don't
remember exactly the value, but was within spec.).
Any help on figuring out the problem will be helpful.

Mike, K4GMH
