[TowerTalk] Yaesu G-1000DXA azimuth indicator not moving

[K0DAN]

Barry:

With luck, you have a connector or cable problem as recently described by 
others.

If the quick + easy approach doesn't work, you need to measure pins 1-2-3 
between the rotator and control box...these should total about 500 ohms, and 
the difference between the wiper and each end defines where the indicator 
points.

The control boxes are known to have mechanical and electrical 
failures...they are rather mechanically involved and are a booger to 
service. Frankly, they are a design and service nightmare, but when they 
work they are a pleasure to use.

I have sent a few controllers to Yaesu, and they do a good job repairing 
them, but they do a "walletectomy" on you. They will not repair the outdoor 
rotator units. I have had mixed results attempting repairs myself, and I 
keep a spare controller around just in case. The good news is the SDX and 
DXA controllers are interchangeable (if you can make up pigtails with the 
correct connectors), and all the 800/1000/2800 series can use the same 
controller.

In a pinch you can hang a 0-20VDC power supply on the motor (pins 4-5) and 
turn the rotator with +/- DC volts.

I'd appreciate troubleshooting help.  I just put my yagi back up after
repair.  My G-1000DXA is rotating the antenna but my control box
azimuth indicator just stays stuck in one position.

Thanks & 73,
