I've had this happen, and it was always a problem with my cable. Anything from a mouse to a connector not tightened. You can check it easily with a voltmeter. I forget which connect is which , but it is essentially a 3-terminal pot. Figure out which one is ground and of the other two, one should be constant (12V?) and the other should vary from 0V at 0degrees up to 12 for 180 degrees El or 450 degrees az. If that always measures 0, then you have a cable problem or else a pot problem on the rotator itself. But with both failed, I'd tend to guess a cable or wiring issue.

Good morning,
Although I will be talking to Yaesu tomorrow, I wondered if anyone had experienced this (and possibly now has a reason/solution to the problem)
I have a brand new G5500 and most of yesterday was spent putting up the mast, rotators and antennas etc.
The control box worked perfectly for a while but then decided to not indicate where the antennas are pointing to AT ALL!
The rotators are working perfectly but the needles are stuck at zero.
The only action they have seen is in the set up and calibration process, there is not even a radio attached to the system at this point - I didn't get that far before the box stopped working.
As I said, I will of course be getting this resolved as quickly as possible with Yaesu and the place I ordered it from but I would be interested if anyone had had the same thing happen.
Many thanks
