i think you are right about the alternator being bad from the beginning. i Am putting a new one in soon. the optima was brand new cuz the one i had before it went bad after 2 years and i got a free one cuz of the warranty, i tested it and it was good. the alt. we put in was a new one from car quest, do u think i should go w a remanfactured one or another brand? or just get the same kind?
