Alternator Testing Diagnostics Are Getting More Complicated
One test is not enough if you are diagnosing a charging system problem. All too often, if only battery voltage is present with the engine running the alternator is condemned as the source of the problem. If this is the case, it means that the alternator is not charging, but does not reveal why.
VIDEO: Check The Battery When Replacing The Alternator
Andrew Markel stresses the importance of checking the battery during an alternator replacement job, and replacing it if it is worn out or will not accept a charge.

VW Beetle, Golf And Jetta: Broken Tensioner, Root Cause Of Failure Is Alternator Pulley
This type of failure is the result of severe vibrations in the accessory belt drive system. While a broken tensioner may be the result, the root cause often lies elsewhere in the system.
How Can You Tell If An Alternator Is Good Or Bad?
A dead battery, an alternator warning light, low charging voltage gauge reading or a “low voltage” warning message would tell you there’s a problem with the charging system, but it doesn’t tell you if the problem is a bad alternator or something else.
Bench Testing Can Reveal If The Alternator Is The Problem
Today’s computer-controlled charging systems tailor the charging rate not only to the electrical demands on the battery and alternator, but also to changing driving conditions. That makes diagnosis much more difficult when something goes wrong.
13 Alternator And Battery Testing And Diagnostic Tips
If only battery voltage is present at the battery on a running engine, does this mean the alternator is “bad?” No, it does not. That only means that the alternator is not charging, but does not reveal why. Therefore, it does not prove a faulty Âalternator.
