I replaced the alternator brushes about 7,000 miles ago, when I pulled the alternator to do the paint job on the fan and fan housing. While I haven't pulled the alternator since then, I am quite certain that all the connections on the alternator are tight and clean, since that's how I left them. I also cleaned the connections on the regulator this weekend, as well as all of the multi-pin connectors to the electric panel. None of that had any effect. The only connection I did not check was the B+ connection at the starter (from the alternator). If that gets corroded, it can interfere with the charge from the alternator to the battery. However, since I am showing over 15 volts at the battery, I presume that the B+ connection is OK. At least, it was about 1,500 miles ago when I cleaned it and relaced the rubber boot over the connection.

I don't want to ignore this, as I have not experienced a glowing light before. Prior to this situation, the alternator light would go out and stay out about a second after firing up. The voltage readings are mostly out of spec. At this point, my assumption is that I fried a diode or otherwise damaged the alternator by leaving the battery connected while on a charger. Looks like I will need to pull the alternator and have it tested, as frogger suggested.

Does anyone have any recommendations for a shop to test/rebuild this alternator?
