Question

Quizplus · Accepted Answer

Both technicians are correct. A full fielding test is indeed performed if the charging system fails the output test, as stated by Technician A, to further diagnose the problem. Technician B is correct in stating that during a full field test, the field windings are energized with full battery voltage to bypass any potential issues with the voltage regulator or wiring, allowing for a direct assessment of the alternator's maximum output.
