i had the same exact problem. tested the battery and alternator, both tested good. came across a fanactic VW mechanic. told him my problem, he test drove it for a couple of minutes. then he told me it was my alternator. my alternator is going bad. so i took his advise, bought a new bosch, and now, new more red light. plus the new alternator seemed to give me more power, thats from what i feel. probably just my imagination.

Pros: more power

Cons: red light

Vehicle: Volkswagen

I had to replace the alternator and battery in my '99 Blazer because the voltage regulator slowly failed, after I replaced them I noticed the dim/flickering interior lights came back to full intensity and the annoying whine coming from my speakers dissapeared

Pros: lights came back, whine dissapeared

Cons: voltage regulator failed

Vehicle: Chevrolet Blazer

my alternator is of the clutched variety. Its from a 1997 and will not contribute to the crank nose keyway issue. 90A Bosch $35 plus shipping

Pros: clutched variety

I had a Bosch reman that self-machined itself to pieces in less than a year on my street car - the car that rarely saw more than 5K rpms. The Bosch replacement seemed to work OK but I sold the car shortly thereafter.

Pros: replacement seemed to work

Cons: self-machined itself to pieces
