Just curious, how long have your stock alternator lasted until you had to replace it? I currently have 112K Miles on my 93 LEV6? It seems ok?....

290.000 miles when I changed the brushes.

Wow you guys were lucky, mine only lasted for about 60k miles with no amps nor subs!

My current Camry, '96 V6, lasted till around 120k miles. My old '92 I4 was original when I sold the car at 190k miles.

Stock alternators are pretty good, and its not really about how much you use it but more about how clean you keep it so that it runs longer. It's not an engine afterall and would run better at cooler temperatures, so keeping it clean and not abusing it by making it do too much work at any point will help extend its life.

201,400mi, and I really do abuse it hard, but I keep it clean and cool.

Had the original alternator for 230k miles, with a 4000w sound system for about 50k of it, and then traded it in for my current car.

Just curious, for those of you who lost an alternator, was it un-rebuildable or did it just need new brushes or diodes? I ask this because the only Toyota that I ever had alternator problems with (a '79 Corolla) was good to go after changing out the diodes (way cheaper than a new alternator, at the time...20-odd years back). I'd figure most problems would be diodes or brushes...both easy to replace, or cheap to have a motor rebuilder do it for you.

FWIW, 105K on my current alternator. She's still a baby.
