Quizplus · Accepted Answer

Both technicians are correct. Technician A describes the correct setup for an AC leakage test, which involves using a digital multimeter (DMM) set to measure AC voltage, with one lead on the alternator's insulated terminal and the other on the vehicle's chassis ground. Technician B is correct in stating that the engine should be run at 1500 rpm during the test to ensure that the alternator is producing a charge and any AC leakage can be accurately measured.
