Alternator Motorcraft or Duralast

Just bought and installed a Duralast Gold from Autozone last week for my '07 9-5. It has a little whine at 2500 RPM but works better than OEM. Has a lifetime warranty and it's 100% new too!

When my alternator failed in my 24v, I replaced the alternator with a duralast, replaced the harness and fuse panel with OEM parts, and 50k later it's still working like a champ.

From personal experience, I'd recommend the duralast gold alternator from autozone. I originally got the duralast regular alternator but I had to change it out it least 2 more times under warranty. The last time I just decided to upgrade to the gold version since I was sick of replacing the alternator, and it's been great for over 2 years now. Remanufactured ones are usually junk, get a new one like the duralast gold one. FYI what usually gives out first is the built in voltage regulator, that's what went wrong every time with the cheaper remanufactured alternator. There might be other good ones out there but that's my experience

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.

Finally, ordered a duralast Alternator which is expected to be delivered tomorrow.

Duralast Gold = new manufacture. A new unit from China. Sometimes OK, but often crap.

All I could recommend is stop buying the autozone/duralast alternators. Buy a good brand, ie Denso, Delco, Motorcraft, etc. and return the duralast one outright for cash in hand.

Duralast..... if you want to get really good at changing them.

I went through 5 of those Durlast gold alternators (supposedly the best version of autozone's stuff) in 2 years before I had enough and bought a the Denso.

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.
