I was cruising the other night. Car running great and then it happened. Radio started blinking on and off, Retard went from 0-13.5 on scanmaster. Went to check battery 9.5v and then she died. I'm thinking alternator seeing as it was a 1 year old rebuild. Am I right are is it something more dangerous? I'm on military duty right now and can't do anything to the car until Saturday or Sunday. A little reassurance would be appriciated. I'm buying a new battery and alternator regardless.
