As described, the job was too easy. The VR seemed to be just fine. I noticed that the bail was off, it holds the plug into the back of the alternator, so I pulled the plug out and cleaned the contacts up with some Radio Shack contact cleaner. Reinstalled plug and its bail, checked voltage at the battery with engine running at idle (13.8 volts). This a.m. there were no issues with the light coming on, so I may have just had some dirty electrical contacts. Also checked the belt, tension was fine. I did not have time to T/S any of the noises, which seem to be mostly loose and rattling stuff, maybe this weekend I'll be able to take a look.

That being said, I've also learned that when the brushes have been too short for awhile, the rings in the alternator are often black or burnt, or both. A little fine sandpaper cleaned up mine so the alternator works again. Hope this isn't a trend or epidemic, but my '92 300D 2.5 wouldn't start this morning - just figured out that the battery is dead. Don't know whether the 2 1/2 year old (84 month) battery is toast, or if the alternator isn't charging yet. This is the only alternaotr in my collection that doesn't have a new VR/brush pack yet. As it will be 20F in the AM, I hope charging the battery out of the son's parked 190D will cure the situation.
