The autopilot controller is ST6002 connected to a Type 150/400 course computer that powers a 24volt Linear Drive (M81134). When the Autopilot is engaged the Clutch acitivates (the wheel locks in position) but the autopilot does not correct course. After a few minutes an error message "DRIVE STOPPED" appears. The rudder limits are all in order. I checked the voltage at the course computer. Supply voltage is 24 volts but the Drive Motor output voltage is zero. Therefore conclude that no power is being supplied to the Linear Drive. Is this a failure of the actual Course compuer or some other issue?
