Quizplus · Accepted Answer

Both Technician A and Technician B are correct. A weak battery can cause insufficient power to turn the engine over, resulting in a clicking noise. An open in the hold-in winding of the starter solenoid can also prevent the starter motor from cranking the engine, leading to a similar symptom.
