In the hydraulic anchor windlass system illustrated, if the power to the electric motor is on, but the wildcat does not turn, the pressure developed on either side of the system increases to half of the normal operating pressure regardless of the direction of movement in which the servo control is placed, the probable cause is the __________. GS-0160

Correct Answer: Option C — manual transfer valve is in the wrong position for the main pump being operated

When the manual transfer valve is incorrectly positioned, the hydraulic flow path is misaligned relative to the pump's output. This prevents the system from building full operating pressure on either side, resulting in insufficient torque to drive the wildcat, as the fluid is effectively circulating through an unintended or restricted path.
