So about 2 months ago, my alternator started making a really loud noise, kind of like a supercharger whining. I replaced it and everything was fine. Well today, about 4,000 miles later, I smell something burning while driving, the alternator is making the same noise again, and the battery light on the dash came on. Luckily I only had to go another 3 miles so I got back no problems. I think its safe to say the brand new alternator is shot...
Could it be a bad PCM that's causing the alternator to die so fast? Is there any way to test that? Hopefully O'Reilly's will exchange the alternator for me, because I have to leave for a 2,500 mile trip on Wednesday.
