First of all normally when the car is running, the voltage on the dash meter reads around 14V. Today I had trouble starting it but got it started and the voltage was around 12V with the car running. Then I drove it home and next time it didn't start. Had it jumped, and it started but the voltage was reading around 10V. When I turn on the headlights it drops to almost 8V on the indash meter. If I'm driving real fast on the highway it reads around 11V.
I think it's the alternator but want to double check to make sure. I thought the alternator was a gradual failure, with me it just seems like it died overnight.

If it is, I have an 01 2.8Q with ATQ engine code and 8GL option. That means it's a 120A. Is there a way to tell if it's Valeo or Bosch? (Do I have to change out the alternator completely, or can I just change bushings, etc?)

Also, is this job difficult to do on the 2.8L?

Thanks!

Sounds to be the alternator.. When mine went in the b5 i just changed it, i dont mess with the bushings. Sounds like your just runnin on your battery mostly

can it be figured out from the options? I know that it's a 120A alternator based on the option code on the trunk sticker.

Not really. Most 2.8's had Valeo. You'll need to put the nose into service position and pull it out the front.

for anyone that cares....mine turned out to be a bosch one
