You sound be able to isolate the issue by swapping the RA and DEC din connectors at the Gemini? end.? If the DEC motor is controlled by the RA buttons with the plugs swapped and the RA motor is now not working using the Dec buttons the problern is in the Gemini box.? The G1 box can be repaired, or you can upgrade.?
If the Dec motor is not controlled by the RA buttons. The problem is the motor or the Din cable.? Test the Dec din cable by using it to connect the RA motor to the Gemini RA port.. If the RA motor works,? cable is good.?
