Low ripple with low electrical loads (peak to peak voltages < 100 mV) and vice versa The scale should be set to a range that can detect low voltages, such as 0-2 volts.

The scope is the same one I used on the Accord— also connected to the battery The scope's vertical scale was the same but the horizontal. The (AC coupled) alternator ripple waveform is centred around 0 V, as the DC component (which may range between 12.6 to 18 V) is removed
Alternator Diode Ripple Test with DLC Health Checker YouTube. The purpose of this test is to check the rectification of the alternator output voltage, where the alternator output is regulated by the Engine Control Module (ECM). The next group of ripple tests occurred on an alternator test machine equipped with a conventional car battery
Diode Ripple From The Alternator. Switch your digital meter to the lowest AC VOLTS setting No significant downward spikes, noise, or missing peaks (dropouts) in the ripple.
