Cable connectors
With the exception of the SeaTalk cables, spade connectors are used
to make all connections to the control unit.
When fitting the spade connectors, make sure the connector fits
securely over the blade and not between the connector and its plastic
insulating cover. Incorrect fitting will give intermittent contact which
will lead to faulty autopilot operation.
Power supply connection
• The autopilot requires its own dedicated power supply – it cannot
source its power from SeaTalk. However, it can be used to supply
power to other SeaTalk instruments.
• You must fit a12 A fuse (or equivalent circuit breaker) to the
+12 V supply.
