pilot not steering a straight course

fault description:

The pilot seems unable to steer straight, it continually overcorrects course errors; the wake has an "S" like appearance as the boat first steers several degrees off-course to port followed by several degrees off course to starboard.

check list:

1.Drive unit: check for any slack or backlash in the drive system.

2.Rudder reference: check for any slack or backlash in the assembly and associated linkages.

3.Boat speed: check that the boat speed input is operating correctly.

4.Settings: read the calibration section carefully and check that the settings are appropriate for the type of boat.

5.Rudder gain: make large course changes using the pilot. If the gain value is correct the rate of turn should be between 6θ and 8θ per second. Adjust if necessary.

6.Boat lag: a boat lag value, which is too small for the boat, can cause instability. Try increasing the value.

7.Check location of compass sensor in vessel. Ensure that the sensor is not affected by the proximity of cables carrying heavy currents, loudspeaker magnets or ferrous metals.
