Is there a universal "fix" to this issue? I remember a track car I used to have did the same thing & we bridged it w/o any further issues.
Thanks!

Uhmm....I own an '85 928S2, the same car as your friend. Are you 100% sure that the alternator is good? I suspect it has simply failed after 25 years of duty. Mine did just that last month, I replaced it with a good rebuilt unit from one of the 928 shops.
The failure symptom: I drove the car to a marina to buy non-alcohol gasoline for my boat [a subject for a post later...], and after filling the 5 gallon plastic container [fits perfectly on my front passenger floor], I went to start the car...but the usual set of illuminated warning lights in German stayed on no matter how hard I revved my engine. I knew what the problem was- the day before, I had had to rev the engine several times to get them to shut off. 25 years and 150,000 miles is a pretty good number for any alternator, so I didn't mind. I called a friend an alerted him that he might need to bring his car to pick me up, but I was only 4 miles from my house and I made it home after 20 minutes of traffic with no problems whatsoever. I have no idea how long a 928 can run off the battery, but it made it for 20+ minutes.
The alternator was easy to install, though there was the usual problem getting the bolt to go all the way through. It just took a bit of persuasion with a small hammer, and me holding the unit this way and that to get it to go through.
Take your car to Pep-Boys and have them check your alternator; they will do this for free, and you'll know instantly where your problem lies. While I would spend the extra $ to buy the new alternator from the 928 suppliers, you can probably buy it in one of those cheap shops rebuilt for less than $150.
Good Luck!
