That $5 junkyard alternator from a guy in Arlington, was he actually right or just lucky?
This older dude at a pull-a-part in Arlington kept pushing me to grab a used alternator off an 04 Corolla for $5 instead of paying $90 for a rebuild, swearing the OEM ones outlast the cheap parts store ones. I slapped it in my 03 Matrix and 8 months later it's still charging fine, but now I'm second guessing if I just got lucky or if he knew his stuff. How do you tell a junkyard part that's actually solid from one that's about to die on you?
