I Was sailing last week and when i went to engage the auto pilot i got nothing. It is a Navico model WP300CX. The unit had power, pushed the button to get a solid red light (where autopilot usually takes over), engaged clutch and i get nothing. when i pushed Port / Starboard course correction button i get a tone and flash of light as before but no movement of the wheel. Belt appears to be in good order and engagement lever is fine. Im wondering if any one has ever had a similar problem with this unit and if so what did they do to carrect it. Thanks All Frank
