RE: [CA11] ST6002 and 400G AST system
Welcome to the Raymarine Forum Deekay911,

The most common components to fail in these systems are the autopilot's fluxgate compass or the autopilot course computer's gyro. One may determine whether the rate gyro (see photo below ... there were a couple of versions of this rate gyro, so its appearance may vary) is responsible for the reported symptoms by simply unplugging cable from the course computer's processor board and then testing the performance of the autopilot. Replacement rate gyros are no longer available and operating the autopilot without a rate gyro would simply cause it to function as a non-gyro assisted autopilot. Should the problem persist with the rate gyro disconnected, then it would be recommended that the autopilot's fluxgate compass be tested per the FAQ found here and replaced if found to be faulty.

If seeking to update the autopilot, please note that the currently installed rudder reference transducer and drive unit may be retained for use within an Evolution autopilot system.
