Alternator AC DELCO or OEM Volkswagen

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.

Put an AC Delco alternator on my Celica because I couldn't get a Denso for it. Wasn't going to buy a store brand reman that'll die in 6 months.

If it was me, I’d go with the ACDelco. Never had any issues with them so far. Checking for the best warranty is something else you might consider, just make sure to read that fine print closely.

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.

Always buy ac delco OEM alternators not part store crap.

Alternators don't make good battery chargers and if your alternator is on its way out then it may not be able to charge the battery. A fully charged battery measures 12.6V when the car is not started. When it's discharged by 75% then it measures 12.4V. if it's like 12V then it's totally dead. When you start the engine and the alternator turns, at idle you should have at least 13.4 Volts. If it's less than this then try reving the RPM's to like 2000rpm. You now should have at least 13.4V. If you don't then you have a problem either with the regulator or you have a bad diode.

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!

alright guys...i charged the battery and it started right up...put my meter on the batter with it running and it just kept going down in voltage over a 10 min span...so i would say the alt is bad...
