ST3000 Autopilot
ST3000 Autopilot Service Manual 83004-2 7
Notes
:
A. Keypads come bonded to facia on later units.
B. Ensure that the fluxgate loom is formed around the outside
of the rear case pillar. Failure to do so may result in the
gimbal action being impaired and the autopilot performance
degraded.
C. Early production units have a spacer (29) which is effectively
replaced by using 4 wedges (27) on later units.
