[TowerTalk] G-800DXA

[K0DAN]

All the Yaesu rotors use +/- DC (approx 9-20VDC) to Pins 4 and 5 of the 
rotator.

Take a voltmeter and measure Pins 4-5 on your controller...as you increase 
the speed potentiometer, the voltage should go up.

Conversely, you can take a variable power supply out the tower and gator 
clip +/- DC to the rotor control cable (be sure to first disconnect the 
controller at the shack).

You should be able to observe the rotator changing direction & speed, and 
can determine if the problem lies in the rotator or the controller.

Good luck.
