Diagnostic Test - Alternator Output Test (12V)
Concept
The alternator is the heart of the charging system. It is an alternating-current generator mounted on the engine, which is driven by a belt from the crankshaft. The alternator develops alternating current, which is changed to direct current. Alternating current changes from positive (+) to negative (-) at a regular cycle. Direct current does not change from positive (+) to negative (-). Only direct current can be used to charge a battery. …showed first 75 words of 397 total…
