Final answer:
A charging system alternator ripple voltage test involves analyzing the alternator voltage waveform for signs of abnormal ripple in Automotive Technology.
Step-by-step explanation:
A charging system alternator ripple voltage test involves analyzing the alternator voltage waveform for signs of abnormal ripple. This test is a diagnostic procedure performed in the field of automotive technology to evaluate the health and performance of the vehicle's charging system. The alternator ripple voltage refers to the AC (alternating current) voltage component superimposed on the DC (direct current) output of the alternator.
