Alright ... what can kill an alternator?
Because apparently one of the answers is me. I'm going through my second one in 4 months.
The OE alternator finally died about 4 months ago due to just ... well ... age and use I guess. I got a new one from Autozone, threw it in there, and its been fine for 4 months until the other day. Granted there's a lifetime warranty on it and all it takes is two bolts and a belt to change, but seriously.
Just looking at it, there's a little bit of mud in it that I should've cleaned out after our trip, but I always get caught working on every vehicle but my own. Then, when I do go to work on my own, I get yelled at for working on vehicles too much ... so is my life. Haha.
So, does mud kill alternators?
