[amsat-bb] Re: Help Desperately with Rotator YAESU g-5400b

[Mark L. Hammond]

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,
