Raymarine autopilot help
We just bought a new Raymarine autopilot for our boat.
New control head, fluxgate compass, course computer, and wheel motor.
We finished the installation over the last few day. The system is stand alone, it doesn't communicate with any of the other instruments.
We went through the dockside setup. No problems.
The rudder can be turned to port or starboard using the +10 -10 buttons.
We went through the sea trial setup, where you do a few turns for the compass to align. No problems.
But, when we try to do the last step, the auto-learn, where the autopilot is supposed to determine the gain and response settings required for our boat, the autopilot turns the boat hard to port, and the boat does tight circles. It doesn't even try to straighten itself out.
There is no error showing on the control head.
There is nothing about anything like this in the manul, or troubleshooting guides online.
Can anyone suggest what to try next?
