What is a basic, practical first step when troubleshooting "dead" equipment that has power available elsewhere on the boat?

A. Replace the entire electrical system as the first troubleshooting step

B. Check the simplest, most likely points first — the fuse or breaker for that circuit, and the physical connections at both ends — before assuming a more complex fault, since a blown fuse or a corroded/loose connection is a far more common cause than an internal component failure

C. Assume the equipment itself is faulty and arrange a replacement without further checks

D. Electrical troubleshooting should never be attempted without specialist tools regardless of the fault

A. Nothing — a test lift can proceed immediately after repairs

B. Testing should wait until cargo operations begin

C. The area within the grab's swing radius should be cleared of personnel before the lift

D. Only the crane operator needs to be aware the lift is happening

A. Who must remain clear of the exclusion zone while the lift takes place

B. The lunch schedule for the deck team

C. Only the weather forecast for the next watch

D. The cargo manifest for the next port
