Alternator Bosch or AC DELCO

Always buy ac delco OEM alternators not part store crap.

Lucky for us, the Alternator was in fact faulty (it was a Bosch btw) and that the previous owner replaced it a few months prior, meaning it was still under warranty.

Bosch is a great aftermarket option.

Yes, if it was from an OEM supplier to Lexus or the auto industry, such as Denso (1/3 owned by Toyota/Lexus), AC Delco, or Bosch, but I would not buy a mystery brand, especially not a rebuilt, because I don't know how much they get rebuilt or tested.

Changed it for another OEM Bosch new (not reman). Subsequent test showed it was now good.

I got BOSCH AL113M from Adv auto (with a code cost me about 80), then went to tractor supply and got several large washers. I took the pulley off my old alt and put it on the new long-nose alt, stacking washers until it lined up.

So my just-installed today reman Bosch SR33X turns the light off with a very slight blip to 1200rpm.

Funny thing is, the Bosch alt. I had in the car at the time is sitting in the car in my driveway. Okay, I replaced the brush pack a few times. The 90 Amp alt. itself is at least 10 years old, if not more.

I figured alternator, so took it to Autozone to scan and everything passed. Then took it to Meineke for them to check and they told me alternator was bad and replaced it. Well my interior lights were still flickering so I took it back and they say seems like the one they installed was defective, so they replace it again with an OEM Bosch and also print me a printout of a bulletin stating that under load lights may flicker and there is no solution.

A friend had a rebuilt bosch unit that he lent me to try and that too doesn't put out any voltage.
