Alternator AC DELCO or Duralast

We just replaced the wife's X three weeks ago. Had the same problem you had with a battery light and brake light. Ended going to AutoZone when we were in vacation and got a Duralast Gold and had a local mechanic do the install.

If you go to autozones website and plug your car info in, what price does it give you for the duralast gold alternator?

I\u2019ve had an ac delco alternator from rock auto in my Honda Fit for 7 years now.

The Duralast one looks to have a lifetime warranty.

Been running a duralast in mine for about a year no problems.

Right on schedule, about 7 months later, that reman also went out and I decided to pay more to get the Duralast Gold which is all new. That one lasted about a year and a half but then the bearings went out on it, but I don't think that issue was the alternator's fault because after I replaced it, I found out the Harmonic Balancer had lost its integrity and was wobbling a little. Again, not sure what caused what (did the bearings put extra pressure on the aging balancer or did the balancer go out and damage the alternator?), but all I can say is that since replacing the harmonic balancer and using the Duralast Gold alternator, I have not had any issues for over 2 years now.

I have a 2007 Chevy suburban and the altenator died so went to Autozone and purchased a new duralast 220.00. This worked for a few days and the battery died again. Checked voltage and only had 9 volts coming from altenator. Took back the altenator for them to bench test and they did not have the proper connections. Gave me another altenator installed worked great for 2 days. This new altenator was also not working and was given a third altenator.

Duralast 11120 (if that's what is on the invoice) doesn't have a lot of great reviews...

It was in fact a Duralast dud! One more example of a “new” alternator being broken out of the box.

I had a new remanufactured duralast alternator as well that I thought was defective but I kept following the power cable off the alternator and found the fusible link.
