Check to make sure that there's power from the alternator to the battery on the charge-back wire. If nothing's there, then your alternator is junk and you'll have to replace it again.

If it's a 3.8 it should have a 130 amp alternator. Sounds like you have a 110 amp alternator and not putting out enough amperage. Ecm thinks that since it's only getting 110 amps instead of 130 amps, something is wrong, so it's warning you that there is a problem.

wires run direct to alternator from battery ,test big lead for a permanant 12v supplyon the back of the alternator if you have one then the problem is either the brushes worn out or the commutator worn through.or the regulator either way its a recon unit as parts are not sold seperate anymore as not many dealer mechanics know how to repair anything and the spares shops make more profit on a unit than parts so they do not sell spares to stop people like me and you from doing our own repairs

Hi, I will keep this short, but just a tip on the tester they use, I had one bench tested and it showed up it was good and the built in regulator was good also. Put it in the auto along with a $75 battery, and the discharge light was still on!!. So, I checked all of the charging circuit wiring finding nothing wrong, and put a rebuilt alternator on. Took care of my problem, the alternator was intermittent, sometimes charging when they checked it at Auto-Zone, but stopped putting out when I put it back on the car. I lived 16 miles from the auto store, so it was a pain going back and forth, plus the cost of gas!! I would change it out if you can at this time. I am sure this is what is going on if all looks good under the hood as far as wiring. Check to see if you have the 75 amp alternator fuse under hood also. It may be gone. Make sure the hot cable to the alternator and wiring plug is OK. Change it out and you will be good!
Sincerely,
