After installing it, all of the intermittent electrical issues disappeared. I'm guessing the old alternator couldn't power all of the electrical issues at once, particularly since the battery light would not come on with the higher rev's of a cold start, but would come on with the low rev's of a warm start.
Sorry for the late reply. just to go ahead and close this out, it was a bad alternator. Took the 400 dollar hit to my wallet and bought a new one. Spent a few hours yesterday replacing it. So far I've driven it about 30 miles without the battery light coming back on. Thanks everyone for the help.
I'm using a MK2 Golf alternator. It has the correct mount width, and has the right frame to mate up with the nice rack and pinion style adjustment bracket also from the MK2 Golf.
The tech who replaced my alternator (@10K mi) left his permanent fingerprints on my hood...have to try to buff it out. Apart from the bad alternator documented in another thread (hopefully a one-off), the car has been great (especially in winter) - no leaks, no sunroof issues, buzzing, rattling, vibrations, etc.
I had to do my alternator a year or so ago in my 07. Considering I got like 240k miles and ten years off the original I went ahead and replaced it with a Toyota OEM one.
First, if your alternator is putting out 13.8V while the car is running, your alternator is fine. Period. If your battery passes a load test after being fully charged, it is fine.
I've had 3 issues with the car: 3. recently - replace alternator (the car just knows I'm about to retire it).
okay so i installed an alternator in my car yesterday, boosted it, let the battery charge a bit, removed jumpers...car stalled.
I have a 99.5 vr6 2.8 afp and missing a alternator ground i think I am getting 20 intermittent ground fault codes and the kid i bought the car from had a alternator put in.
My Rabbit's alternator lasted a solid 40,000 miles!
