S1G autopilot controller

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Dave,

Unfortunately, parts and service are no longer available for the S1G. Additionally, I don't believe that software would be responsible for either of the reported issues. I would recommend that the Raymarine’s web siteautopilot's rudder reference transducer be tested. Should the rudder reference transducer pass tests, then you may want to try testing the performance of the autopilot without its gryo. This may be accomplished unplugging the gyro from the processor board (it's the only component which is connected to the processor board via a cable w/plug). Should the problem abate, then it would appear that the course computer's gyro has failed. Using the S1G without a gyro will simply permit the autopilot to function as a S1 autopilot. However, should the problem persist thereafter, then it would appear that the course computer has suffered a failure necessitating its replacement. Drive units installed for use with SmartPilots may also be used with Raymarine's Evolution Autopilots.
