Alternator OEM Mazda or Duralast

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 agree, alternator from autozone is not bad. I replaced mine with a Duralast and never had a problem so far.

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.

When I lived in walking distance of a 24-hour AutoZone, there seemed to be more people waiting in line to get their lifetime-warranted DuraLast alternators replaced than for battery replacements.

And while I dont recall Hyundai being one of them, there are certain make/models that need an OEM alternator or they just wont work right (i.e Duralast Alternator in a BMW X5=bad idea)

2 weeks ago, my 120amp Bosch crapped out on my '95 GLX. Decided the Duralast route wasn't a bad direction, being it's actually an OEM Bosch alternator, that Duralast performs the remanufacture on, with their own regulator, brushes, and bearings. It was also stated that they had numerous testing fazes performed after the rebuild. I had a 25% off coupon, and $40 in Autozone credit points. Walked out with the alternator for around $90, being the 120amp alternators are more expensive. Took care of the install, started it, power held, and she ran beautiful. Then a few minutes later, I started to hear a bearing scream. Was worried it was the alternator, as that was the only factor that changed, aside from disengaging the tensionar pulley and removing the serpentine belt during the alternator installation. 2 days later, cars sitting there warming up, hear the RPM's start to change, the gauge cluster display starts to dim, the door chime weakens out, and the car dies. Wouldn't you know, that Duralast alternator **** the bed with less than 10 miles on the rebuild.

I'm surprised Mazda is rated so poorly, I had a Mazda MPV for 8 years and honestly the only problem I had was the driver's side window gear was worn out, and the alternator.
