killing alternators

Odd issue I am working through. i replaced my alternator back in march with an autozone unit. everything's peachy, then after a couple of months it dies. cuss a bit, then swap it out for another, hit july and it dies... cuss a lot more, then swap it out for another... now september and it is not putting out a charge again. i am believing it may not be bad alternators from autozone and I may just have a little bigger issue now. any suggestions where to start? The battery is a few years old and holds a charge well. I am not tripping any fuses. no thumping sound system...

Replace the battery, or at least have it checked. I had a car like that once and even though the battery seemed fine, it was killing alternators. Once it was replaced I never had another issue.

Sounds simple enough. will give that a try

EXACT thing that was happening to me!!!

I killed 4 autozone Miata Alternators in 3 MONTHS!
ended up being the battery. Fail.::BaHump::

the bonus is i could change alternators for a pit crew now..

thanks for the help guys!

I just put one of these in our '02 FWIW - http://www.staabbattery.com/category...Batteries.html

thanks for that as well. ended up replacing the alternator in the expedition this weekend as well. i seem to be electrically challenged, or not well grounded..
