Alternator OEM Nissan or Duralast

Autozone one here. 3 years deep going strong

Replaced the 2017 ACDelco alt with a Duralast Gold 160 Amp. Life time warranty. For 200 bucks at Auto zone. Hope this is the last one I buy.

I purchased a 2002 Nissan Quest alternator for my 2002 Xterra. It bolts right up. 120 amps instead of 80 amps.

I'm a little biased towards the Z32- Winter mode Summer wheels I love how it drives, feels and looks. ~80k miles since 2003 I've replaced the alternator a couple times, high pressure power steering hose, a couple injectors, the clutch twice and many tires.

I went and purchased an OEM alternator from Nissan and it is still not providing power. I have triple checked all the connections on the alternator, and have verified they are running 12V when the engine is shut off.

I ended up replacing the alternator but it wasn\u2019t a genuine Nissan part and it didn\u2019t work.

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.
