Hello Vincenzo, some years ago I had the same problem with my KR-500 elevation rotor. The reason: The little wheel on the shaft of the potentiometer that rotates the poti when the rotor is moved slipped on the shaft and the poti remained in the left end position. The wheel is attached to the shaft with an allen screw to prevent it from slipping. The screw had loosened. All I had to do was tighten the screw. But as Jarda, OK2GZ, suggested: First measure the resistance between the 3 wires to the potentiometer at the control box to see whether one of the wires is broken or disconnected.

Hello,
today while I was doing satellite activity, I had not
under the eye the Yaesu G-5500 control box.
I have turned my eyes to the control box and have noticed that
The Elevation needle on meter shows 0 degrees.
The antenna are moving because if I press the UP button I can see the
Antennas moving UP while if I turn them Down I can see them going down. The only problem
Is the needle on the meter that does not move and it is stopped on 0 degrees.
The Azimuth side is OK.
What could it be? Something in the Control Box? What can I try to see if the problem
Belongs from the control box in the shack or on the roof?
Any help will be really appreciated.
Thanks
