Autopilot does not hold heading.
1. Did you calibrate the compass?
a. Calibration must be done for the autopilot to work correctly.
2. Has some kind of magnetic interference been introduced within 24”
of the Compass?
3. Is Compass Ball and Bracket fi rmly mounted?
4. Are the wires pointing down out of the Compass Ball?
5. Did Autotune perform correctly? Refer to the Sea Trial Setup section in
your Owner’s Manual.
Compass Calibration fails. (If the up and down arrows both blink and
the warning horn sounds, compass calibration has failed-you must turn the
system off by holding the Deckmount on/off button down in order to try calibration
again.)
1. Check for magnetic disturbances
a. Be at least 24” from speakers, iron, radios, etc.
b. Do not calibrate compass on the boat trailer.
c. Be sure you are on smooth water.
d. Be sure that you continue turning starboard and do not turn back to the
port.
Shadow Drive is being “false tripped” (autopilot disconnects
when the helm is held steady)
1. May be due to air in the steering system.
a. Check for air, and re-bleed if necessary.
1. Remove all trapped air in the new hydraulic hoses from AP pump
2. You must turn off Shadow Drive (code367) and steer lock to lock using the
Autopilot.
2. May be due to leakage of fl uid past the helm pump lock valve.
b. Repair Helm valves.
3. Check location of Shadow Drive.
c. Must be located near the lowest helm, or last helm in line before the pump
unit.
d. Must have short length of hose between helm and Shadow Drive.
e. Must be mounted horizontally and as level as possible, and away from magnetic
interferences such as
electric motors or speakers
f. Single helms must not have a Tee fitting before Shadow Drive Valve. See
hyd Layout.
Autotune fails. (Both the Up Arrow LED and Down Arrow LED will blink
for 5 seconds)
1. Repeat the Autotune several times. If it fails each time, check the following.
a. Try fi nding smoother water if conditions are rough or windy.
b. Do not change throttle settings once the autotuner has been started.
c. Engine speed is too slow or too fast.
Autotune seems to be OK; then the next time you start autopilot it
behaves as if it has not been tuned.
1. Did you download into permanent memory the autotune?
a. You must download the autotune before turning the autopilot off.
When starting Autotune the autopilot immediately turns in circles.
1. Hydraulic Hoses are backwards.
a. Use code 249 to reverse hydraulic hoses.
When in navigation mode the Autopilot heading does not match GPS heading.
1. Was North set on the Autopilot? To run a GPS Course requires that the autopilot
compass is in agreement with
the GPS’s magnetic map.
2. Are the GPS outputs turned on and correctly formatted? NMEA 0183.
a. Sentences needed are RMB and RMC only. Un-needed sentences that are turned
on may cause
autopilot to drop out of navigation mode.
