Cal-Van Tools' Quick Ripple Tester, No. 73, can easily and efficiently test alternators for a variety of issues, including excessive ripple, through the DC Cord outlet in the vehicle (i.e. the cigarette lighter). The tool specifically tests the alternator, diode, stator and intermittent diode and pinpoints the exact problem, cutting alternator diagnostic time drastically.
