Alright, so my alternator died a little while ago, and I've replaced it with a new one that I bought off of ebay. It's a 140 amp and its suppously brand new. Now, when I start the car up it rattles like crazy, and it didn't do it before I replaced the alternator. The car charges just fine, so do you just think that the rattle is from a winding in the alternator or something? I don't really know...any info much appriciated...
