Steve,
I am not quite sure how You have wired up the rotator. As far as I know, the
G-800S, G-1000 use the same wiring, and they need minimum 5 wires.
The indicator use 3 wires, 0V, 5V and one for the feedback from the pot
meter. In addition You need two wires for the motor, this is floating
DC voltage
12-24V depending on model (plus and minus depends on turning direction).
There is no common ground shared between the indicator and the motor.
In the G-2800 there is also a sixth wire which are connected to an additional
pair of limit switches.
regards,
