LOW VOLTAGE, NOT CHARGING

Question

AUTOZONE SAID BOTH BATTERIES ARE PERFECT ALTERNATOR IS GOOD

Answer 1

Low voltage not charging, This is the alternator, if you are installing a rebuilt or remanufactuer you are going to have trouble getting one that works If you have a single alternator the specification is for a 110 amp alternator

This is a rebuilt alternator the specification for a good charging system should be at 13. 20 volts to 15.5 volts at idle. This benched tested good but installed the alternator is faulty. Removing it and replacing it is going to be a hobby until you get a good one. Think of this as going fishing.
