Hi All, I’m having a problem with my 2005 Scion xB. A 1-year old battery died on me in January, and the problem was diagnosed as the alternator overcharging the battery. I replaced both the alternator and the battery, but two months later, the new battery has died. The battery appears to get a norm…

Today, “rebuilt” alternators are not very reliable…Have it tested…The best way is off the car…
