Luckily he was only 8 mins away from home so I just followed behind him as he drove it home. Find the receipt to when I did it, Geez, damn alternator didn't even make it a year. I did this job 9/16/12... Luckily I have the receipt and a warranty attached to that sucker...
In any case, for those of you with alt problems (And there are a few of you on this board right now) try your best to get an OE Alt from BMW.) I think I read somewhere you can get a reman'd BMW alt for $400? If thats the case do that. I know last year when I was looking into it, it was $750 for the new alt from BMW.. so I said WTH, took a chance and bought one from Pep-boys Bosch reman'd.. yeahhhh... I'm guessing they just painted it, degreasified it and slapped it back in the box.
Uhg, the flash backs of the STUPID PS hose getting in the way is already rattling my bones. Oh well... time to do some wrenching!

You should have checked the resting battery condition as soon as the light came on (let sit for 8 or 10 hrs, V should be over 12.4). If you have a bad battery and continue to drive until it no dies the alternator will be fried.
You can also damage numerous electrical item driving with low voltage, as volts drop, amp draw rises. Blown fuses are best case, worse case big $.
