Stores are reporting scenarios exactly where GM vehicles and specifically Chevrolet Impala alternators are overcharging the battery. The charging procedure in these newer GM automobiles is a great deal more complicated than simply a traditional voltage regulator and alternator.

Corrosion any where in This technique can develop significant voltage drops that can really mess up the Directions into the alternator. So usually start by conducting voltage fall checks.

The newer vehicles have alternators which happen to be "temperature compensated". This suggests they cost at distinctive voltages according to the temperature.
