Asked by Feb 03, 2017 at 01:22 PM about the 1996 Isuzu Trooper 4 Dr S 4WD SUV

Question type: Maintenance & Repair

When I replaced the alternator and took it to the parts store they tested it and stated the regulator was bad.  Removed the alternator and took it in and they tested with their equipment and was told that the alternator was good.  I have three ECM control boxes I know that are good and it still does the same thing 12.6 volts

A slipping belt could cause low volts, did you change the belt as well?
