[amsat-bb] G5500 control box issue

[Burns Fisher]

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.
