You are absolutely correct. Each drive has a clutch.
Therefore, I would check the wiring as the fault is on both drives. Possibly the rotary switch that connects one drive or the other. The Course computer is definitely a suspect. One time my S3G started to seek and not head in the direction that the control head was set for. I spent over a hour with Raymarine on the phone trying to calibrate the computer.. They said I was doing something wrong. I said I will just swap out the course computer with my spare.
They said I would have to recalibrate it. It did lock on immediately without calibration.
I sent it to the chief poobah at Raymarine and he found a cold solder joint on the circuit board.

Correct me if I'm wrong, but doesn't each drive have a clutch? Our boat has two drive units, a linear and a rotary. We have the same error for both drives so I doubt that both clutches / drives failed simultaneously.
