Faults and Fixes
The batteries are not charging — how do I identify an alternator fault?
Measurement separates an alternator fault from a battery fault: if the voltage at the battery terminals does not reach the expected range with the engine running, the problem is on the charging side. Belt tension and the regulator are part of the same chain.
Why it works this way
That measurement is taken during a survey and the connections are additionally scanned with a thermal camera, since a hot joint produces the same symptom as a failing alternator.
