how to check Altornator Diodes using a oscilloscope | AC ripples test | Hscope & Hantek 6074be
in this video demonstrate how to diagnose the altornator diode plate (rectifier) without removing the altornator.
for the testing method in this video we use Hantek 6074BE Automotive oscilloscope and the Hscope software run on the Launch x431 pro auto scanner Tab..
in this method we looking for AC voltage on altornator B+ post. if a good altornator it should be lower than 500mV and should have a consistent pattern of ripples.
