[CA] [CA11] Uncommanded 360 while in track mode

[Chuck - Raymarine - Moderator]

Welcome back to the Raymarine Forum hynespa,

The reported symptom would typically be indicative of
- introduction of a magnetic field in the area of the fluxgate compass ... inspect the area around the fluxgate compass for sources of magnetism, particularly nearby electrical devices which may switch on / off automatically.

- a problem with the autopilot's gyro ... unplug the gyro's cable from the autopilot course computer's processor board. Unfortunately, replacement gyros are no longer available for the S1G/S2G/S3G autopilot course computers. The autopilot will no longer be gyro assisted autopilot and will accordingly function as a S3 autopilot course computer.

- with the fluxgate compass ... the fluxgate compass test should be performed and replaced if binding is detected or resistance measurements are not consistent with those specified within the fluxgate compass test
