The Shadow Drive of the GHP 10 Autopilot isn't Disengaging Properly

There may be a few reasons the Shadow Drive does not disengage the Autopilot.

It is recommended that you first check the installation of the Shadow Drive valve. Ensure the Shadow Drive is mounted horizontally and that the proper fitting (if applicable) is applied to the Shadow Drive. If the Shadow Drive is mounted and wired correctly, continue to the next troubleshooting step.

Second, ensure that the Shadow Drive is not disabled in the controls of the GHP 10 Autopilot. Refer to the owner's manual for instructions on how to enable the Shadow Drive.

If after these troubleshooting steps, the issue is not corrected, the problem may be a faulty Shadow Drive.
