I'm used to checking the 5400 series rotors. A quick check I have used is to swap the AZ and EL connections on the rotor control box. If the AZ rotor moves using the EL control the problem is in the control box. If it doesn't move I'd do the continuity check of the motor leads, they should match the EL readings pretty close. At least those checks can be done on the ground.

Good luck//Dave WB9YIG

Assuming the cable connections between the yaesu control box and the rotor is intact, it may be the motor driving  the azimuth. I had the same thing and the motor had developed an open winding. The end result was I had to rewind one of  the motor windings. Kb5wia has a web site on how to do it.

Hello,

today after done a couple of satellites,

I have noticed that the Antenna did not go to the parking position on the Azimuth side.

I have tried to move them manually with the Azimuth Left and Right switches on the Control box

But the antennas did not move.
The Elevation side is OK.
Please 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 from

The rotator on the roof?
Any help will be really appreciated.
Thanks
