Another alternator dead

Hi guys, this car has been nothing but problems for me since i bought it, i truly regret it. Anyhow, i replaced the alternator about 2 months ago and today it died on me again, Anybody know why my car eats alternators like this? What are the possible reasons. Its too dark right now but tomorrow ill check to make sure that all the connections are tight, hopefully not but im never that lucky.

a bad battery will kill an alternator too. if the alternator has to full field all the time it will burn out quickly, the battery may just hold enough juice to start the car, then, doesn't put out enough to run the car, so that the alternator has to run the whole car, lights, ignition, fuel pump, and the countless other things that are electric.

if the alternator is from a junkyard, then it's used...not much more to say.

if it's from a store, then it's in need of being replaced for free.

check your voltage output with the car running and not, or have it tested at Autozone or the likes.
