Alternator AC DELCO or GENERAL MOTORS

Remy and AC Delco are good. I have never had any issues with WAI parts and I had not had any real issues with BBB until very recently.

I had the AC Delco alternator (an OEM part) in my 1994 Saturn SL2 rebuilt in 2015 by Alternator & Starter Co. At the time, no new OEM or aftermarket alternators were available for a Saturn that old, and the guru who advised me on Saturn repairs told me I would have better luck with a local rebuild rather than a commercially remanufactured replacement.

I'm showing a new acdelco 135amp alternator for roughly $163 plus shipping through rockauto.

Acdelco is oem for GM. They make high-quality parts, never been disappointed by one.

ACDelco makes a brand new alternator for $95. They were the OEM for GM.

I went with RockAuto as well, but went with the AC Delco Gold Reman that was wound to have 135 Amp output instead of the OEM standard (~110 I think) I want to say it was around ~$170 with a $45 core deposit. AC Delco is a solid name in parts, and I believe was reman'd in Mexico.

The OEM alternator is only 55 amps and costs nearly $400, which is stupid expensive and wholly inadequate for off-road lighting, audio amplifiers, and other additional accessories so I decided to go with the CS130D GM alternator, purchased for under $100 new (no core charge) and has a 130 amp capacity.

I'm getting 14.8v from the upgraded alternator at 700rpm and maintaining 14.2v when every possible accessory and light is turned on at idle.

i had an equinox do that to me. Kept eating alternators. They were new AC Delco ones too. I just got a used OEM one and has been fine.

I got an ACDelco reman alternator from RockAuto, but it has a grinding feeling and bearing noise when I spin the shaft by hand. I'm not putting that "reman" alternator in the car only to have it fail a few weeks from now.

ACDELCO because if I get another API alternator that’s defective I’m going to kill somebody

three alternators in a Cadillac, even "new GM" are remans, only way to get a new one (never installed, made of new parts, new for you) is to buy a new car.
