What can kill an alternator?
Everyone in my family seems to destroy the alternators in their cars. I have no idea what they are doing or if all the mechanics in Jersey are shady. I just bought a 2007 Ford Focus & I actually noticed on the Carfax that the original owner replaced the alternator at 50K miles. I've personally never had this part go on me on any car I've owned. What do you think is happening?
