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 _______________. Illustration GS-0160
AI Explanation
The correct answer is C) the manual transfer valve is in the wrong position for the main pump being operated.
In a hydraulic anchor windlass system, if the power to the electric motor is on but the wildcat does not turn, and the pressure on both sides of the system increases to half of the normal operating pressure regardless of the direction of movement, it indicates an issue with the hydraulic system rather than the electric motor. The most likely cause in this scenario is that the manual transfer valve is not in the correct position for the main pump being operated. This would prevent the hydraulic fluid from flowing properly through the system, resulting in the increased pressure on both sides without the windlass turning.
The other options are incorrect because they do not address the specific symptoms described in the question. A broken replenishing pump coupling would not cause the pressure to increase, the relief valve not opening would lead to full system pressure, and an incorrect spring set point for the pressure control valve would not affect the directional control.
