Diagram for question 404
AI Explanation
The correct answer is A) stern light "2" burns out. When a stern light circuit fuse blows open, the stern light "2" would no longer receive power and would burn out, giving the same indication as if the stern light itself had burned out. This is because the stern light circuit would be interrupted, causing the stern light to extinguish. The other answer choices are incorrect because they do not directly relate to the indication that would occur when the stern light circuit fuse blows open. The stern light trouble lamp, trouble buzzer coil, and trouble relay would not provide the same indication as a burned-out stern light.
