Hello Enzo,
If I had that problem, on the rear of the control box I would reverse the
"UP" and "DOWN" wire connections (2 wires only; I think they are contacts 4
and 5, but please double check on your schematic!). You can then determine
if it's the rotor, the controller, or a wire connection.
73,
Mark N8MH

IK8OZV:
I just had EXACTLY the same thing happen to me. I took the rotor apart
and discovered that the motor had failed. It would NOT rotate in the
"down" direction. I was able to free it --------- I put the whole
rotor together -------- only to have motor freeze in the "down"
direction. My conclusion was that the bearing in the motor had failed.
Fortunately, I happened to have another elevation rotor and replace the
whole elevation unit. I did not investigate whether I could purchase
just the motor, you may wish to do that.

Enzo,
You have gotten some good suggestions. Some time ago, my G-5500 did the
same thing. The failure was in a phase shift capacitor used by the motor.
Without the capacitor, the motor did not have enough torque to move the
elevation down. Fortunately, at least according to the schematic, that
capacitor is in the control box with the G-5400. (It is in the rotator in
the G-5500.) Fixing it, if that is the problem, should be cheap and easy.
The capacitor is about $10 USD.

Hi Folks,
hope in an help to solve my problem with my Rotator Yaesu G-5400B.
Today i was tracking the ISS, ad while i was tracking it I got The AO-51 in
AOS. As I am using the Trackbox, and i did not have under my eyes the
control box, I heard the Trackbox passing from ISS to AO-51. I gave an eye
to the control box and saw it was stuck at 35 degrees and it did not go
down to the 0 degrees to start the AOS. I have pulled out the connector
which connects the control box to the Track box and tried manually
To bring down the antennas. I've tried to press the "DOWN" switch, but they
did not move from that position.
I've tried to press the "UP" switch and noticed that the antennas moves
going up.
Then i have tried also with the "RIGHT" and "LEFT" switches of the Azimuth
and noticed also that the antennas moves in both sides.
At the end i can say that the antenna moves in all the positions except for
down.
Please anybody can tell me what is happened?
As the antennas are now stuck at 45 degrees i am afraid that the wind can
cause problems.
I Hope in an help.
Any help will be really appreciated.
Thanks in Advance

Enzo,
Use the idea of switching the wires before you do any disassembly
instructions.
Use the simplest of tests first. There is an age old theory of Keep It
Simple Stupid (KISS) and this
Adage can be used in any testing theories. It has served me well in all my
troubleshooting adventures.
Good Luck.
73,
Dee, NB2F
