Raymarine auto pilot no signal

[Glenn Cook]

Hi does anyone have an idea my ray marine auto pilot is only giving me three straight lines instead of a degree, I have check fuses. And lead connections, Chart plotter is fine just auto pilot display not working

Is the auto pilot actually working, even without the display? I suspect the answer is no which suggests something wrong with the course computer or the connections to it. It might be helpful if you posted which actual model of autopilot/course computer/smartpilot you have.
