though the Port or Starboard output LED is lit
on the autopilot front panel.

or a CP1L Hydraulic Linear Actuator, or with an
existing reversing electric drive system.

autopilot and the control box, making sure that
none are reversed.
b) Remove the cover of the CT1T Type 1
Control Box and check the setting of the
minimum speed potentiometer for too low a
minimum speed.
