Question 363General Subjects - QMED

The correct answer is B) relief valve "L" is not closing. If the wildcat is turning slowly or not at all, even without a load, and the pressure on the high side of the system is nearly normal, it indicates that the hydraulic system is not functioning properly. The likely cause is that the relief valve "L" is not closing, which allows the hydraulic fluid to bypass the windlass and prevent it from turning at the expected speed. The other options are incorrect because: A) the manual transfer valve position is not relevant if the system is not functioning properly; C) a broken replenishing pump coupling would not cause the specific symptoms described; and D) the pressure from "E" bleeding off when "J" is in the operating position is not the issue here.
