THE AUTOPILOT TURNS
ON, BUT DOES NOT TURN
THE RUDDER.
(continued
from page 56)
Check for full output voltage on the SWITCHED PWR line
with autopilot in the
POWER STEER
mode. The yellow SWI
POWER LED in the distribution box should come on when
the master select switch on the autopilot is in the
POWER
STEER
or higher mode.
Check that the voltage on the PORT OUT and STBD OUT
lines drop to less than 1.5 volts when their respective keys
are pressed.
Check the rudder drive for correct operation. For a 12 volt 4-
way valve, the common line from the solenoids must be
connected to UNSWITCH.PWR (terminal 3 in the
distribution box), rather than to SWITCHED.PWR.
THE RUDDER TURNS
HARD OVER TO ONE SIDE.
Check the rudder follower for correct operation.
Check the rudder drive for correct operation (i.e. sticking
relays, sticking solenoid valves, etc.).
If the rudder appears to move normally with the autopilot in
POWER STEER
, but goes hard over with the autopilot in
PILOT
, recheck the rudder follower and rudder drive
connections in the distribution box for correct hook-up.
Perform the dockside set-up again.
THE AUTOPILOT TURNS
ON, BUT DOES NOT
OPERATE PROPERLY.
Turn the master select switch to
OFF
and then to
STANDBY
to restart the computer program.
Check the voltage in the distribution box for a minimum of
10.0 VDC between PILOT PWR and PILOT COM.
Check for problems in the cables leading to the optional
remote controls by unplugging them from the rear of the
autopilot.
THE DISPLAYED COMPASS
HEADING DOES NOT
FOLLOW THE ACTUAL
COMPASS HEADING
PROPERLY.
Check for any compensating magnets, particularly heeling
magnets that are placed too close to the fluxgate sensor.
Check for any magnetic material such as tools, tin cans,
etc., near the compass, or directly underneath it, perhaps in
a drawer or cabinet.
THE AUTOPILOT STEERS
NORMALLY ON SOME
COURSES, BUT NOT ON
OTHERS, PARTICULARLY
NORTH OR SOUTH.
The problem most likely lies with poor compass adjustment.
Contact a compass adjuster to have the compass
compensated for deviation, including that caused by heeling
error.
Proper compass adjustment is particularly important
on steel-hulled vessels. Do not attempt to move any
compensating magnets yourself, as this may make the
compass dangerously inaccurate, particularly if it is used as
a steering compass.
