In attempting to start the hydraulic pump drive motor of a horizontal electro-hydraulic anchor windlass, what condition would prevent the electric motor from starting?

AFailure to start could be the result of an electrical interlock associated with the hydraulic pump stroke control being in other than the neutral position.
BFailure to start could be the result of an electrical interlock associated with the wildcat clutches being disengaged.
CFailure to start could be the result of an electrical interlock associated with hand wheel operated wildcat band brakes being set.
DFailure to start could be the result of an electrical interlock associated with the hydraulic pump stroke control being in the neutral position.
AI Explanation

The correct answer is A) Failure to start could be the result of an electrical interlock associated with the hydraulic pump stroke control being in other than the neutral position. This is the correct answer because the hydraulic pump stroke control is typically interlocked with the electric motor that drives the hydraulic pump. If the stroke control is not in the neutral position, the interlock will prevent the electric motor from starting in order to avoid unintended operation of the anchor windlass. The other options are incorrect because they do not directly relate to the condition of the hydraulic pump stroke control, which is the key factor in determining whether the electric motor will start.
