vs
Alternator GENERAL MOTORS or Duralast
Reviews
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.
Pros: working like a champ
Mileage: 50000 km
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
Pros: great for over 2 years
Cons: remanufactured ones are junk
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.

The alternator itself can get bad only if the bearings are shot. If you don't have play on the shaft, and it spins freely then the alternating part of the alternator is fine. What can get pretty bad are the diode rectifier bridge.
Pros: spins freely
Cons: bearings shot
I want to hear an opinion on getting a duralast alternator and popping it in my n52 I have heard very mixed things about these parts some work fine others are trash.
Cons: mixed reviews, some trash
IMO duralast doesn\u2019t last no where near as long as a good quality Bosch/Denso alternator.
Pros: good quality Bosch/Denso
Cons: duralast doesn't last
I got a alternator from AutoZone( duralast pos) and a new battery , same thing, car started with new battery ,voltage at the battery was around 12.5 and voltage directly on the alternator was the same exact voltage as the battery which showed the alternator still wasn\u2019t charging I took that alternator out got my money back and went to a reputable alternator and starter shop around my area and got a quality rebuilt one. They tested the alternator before they gave it to me and confirmed it was in working order. I installed it and still the alternator is not charging the battery , i checked voltage directly at the new alternator and still got the same voltage as the battry while the engine was running , so its still not charging the battery or producing power
Pros: quality rebuilt alternator
Cons: alternator not charging
Vehicle:
Toyota
Believe it or not, though I installed a brand new alternator(Duralast gold) that turned out to be bad from the start and I had to replace it again(so I guess what I’m saying is check the tention on your belt, but don’t rule out the new alternator as - also - being bad), been 2 years since tho.
Cons: bad from the start
I purchased a Duralast 115A Alternator 14921 (remanufactured) which, once we moved the pulley and fan from old to new, it mounted up without a hitch. Once the battery was charged I connected everything up and she started right up. However, the voltmeter was hanging around 12V so we put a multimeter on the battery and only saw 12V+/-.
Pros: mounted up without a hitch
Cons: voltmeter hanging around 12V
Vehicle:
Porsche
Part number: 14921
Wouldn't recommend AutoZone based on my experience. Had a duralast gold fail on me and had to get a replacement one.
Cons: duralast gold fail
