Alternator VALEO or AC DELCO

Hi all, after a long time, the problem solved by instaling a non refurbished Valeo alternator. Same one as the refurbished was.

Replaced the alternator and everything is cool, but I'm keeping an eye on it. Oh, and the brushes on the voltage regulator from the old alternator were shot, no wonder the ozone smell, they were barely making contact. This is a Valeo alternator, not the Bosch, and the car is a 2.0 AT.

I had to replace my alternator as well....low voltage in the battery will cause faulty gauge readings and irrelevant warning lights until all is restored....I went with a 120 amp Valeo; the pulley had to be swapped from my old alternator...

But its a Ford truck/suv and the alternators ALWAYS go bad on them. Word to the wise, buy an AC Delco replacement or Ford OEM, anything else will just die again-they always do.

I have a 1.8t motor in my Passat; but, I had to replace my alternator last January....and I took some pics...I went from a 90 Amp Valeo to a 120 Amp Valeo....the pulley had to be switched over to the new rebuilt unit (I went to an Alternator/Starter shop) ....old one on the left (90 A Valeo)....new one on the right (120 A Valeo)....

Thanks for the help Waynep, ended up replacing the alternator itself and now its working like a charm!

I had a Valeo alternator from an 03 Jetta in my garage, so I slapped that in and made the connector work somehow. Its working perfect now. 14.5v almost instantly at startup. Weather is below 30F.

my car had a 120A valeo, total b!tch to get out even with the front end removed, hard to get the ground wire off, will put the new one on in the AM

My mk3 golf is at the shop right now because I installed a replacement valeo alternator and it didnt seem like a perfect fit and shredded up the serpentine belt. I think the shop I got the replacement from gave me a bad fit.

Another good way to tell your alternator is going is the battery light illumination. I noticed as I drove to higher RPM's, used the vents or even used windows with more power gave more illumination of the battery light. Tested the alternator at a shop and found it to be weak, battery was fine.
