[TowerTalk] T2X Rotor problem

[Dave Thompson]

OK Gang.

I just got my beams back on the tower and I tried to turn the T2X off North to NNE so I could work Europe/parts of Asia while I await the tree guy to allow me to turn the beams though 360 degrees.   Trying to turn the beams East nothing happened.  I then turned it slightly West and it went about 15 degrees and all of a sudden the indicator dropped to S by West.  I then ran tests to see if I could detect the problem from the ground.  Follows are the results:

Resistance Tests:  Brake solenoid  terminals 1 and 2 1.2 ohms
1/2 motor winding terminals 1 and 8  5 ohms
1/2 motor winding terminals 1 and 4  5 ohms
1/2 motor winding & switch  1 and 6  open
entire motor  terminals 8 and 4  open
right limit switch 8 and 5  8 ohms
left limit switch  4 and 6  2 ohms
entire pot switch  3 an 7   500 ohms 
pot arm to + end  3 and 1  50 ohms
pot arm to - end  1 and 7  100 ohms

Voltage Tests;  Terminal 1 and 2  30 V AC with brake depressed
terminals 1 and 5  30 v AC with brake and CW depressed
terminals 1 an 6  30 V AC with brake and CCW depressed  
terminals 3 and 7  should be 13v AC but nothing.

Remember the rotor was pointed at NNW and 100 feet cable attached.  

What I question is why 2 readings are open and I could get no AC reading on 3 and 7 with AC power on then depressing the brake then with either CW and CCW depressed.

The rotor and antennas were installed by a tower pro so someone will have to climb up to see the problem or problems.  The rotor was working before and tested before it went up on the tower.  I wonder if the open says some wires are not attached any longer.
I also worry as the rotor (still no directional reading is pointed at about 330 degrees so it has moved again CCW. I used new hardware for the rotor and maybe it is loose.

For over 60 years I had a crank up tilt over and did all my own work.  I now depend on someone to climb the tower and fix the problem.

I hope to get another T2X but any ideas of the problem (s) would be appreciated.
