Well I went on @AH64ID suggestion and took a trip on down to Durobilt yesterday with the alternator from the 1996 Dodge 1500. Its a small shop in Nampa ID. Amazing to walk in and look at his stock he carries everything for starter and alternator from small cars to full size industrial application. Now moving on to my alternator he bench it quickly and it passed. I quickly told him I was having high AC noise issues. So he hands off the alternator to his crew man there while he show me around the building. Within about 2 to 3 minutes his employee had it pulled apart and the brushes were at thew limits just barely making contact. This would be my source of AC noise from the arcing of the brushes. He cleans up the slip rings and installs a new set of brushes. Re-test and good to go. Maybe 15 minutes total. My total cost was $40.50 for that alternator fix. That was way cheaper than a full replacement.
Thank you @AH64ID for the suggestion that was worth it!
