today i went threw 3 alternators (cuz i thought they werent working properly) trying to solve my battery drain. from fully charged battery will put out 12.3 or so and the alternator will put out around 11.7 when running. i know it should b 14 something so. when i drive it for 10 mins or so it completely loses all power. the fuse works so thats ruled out. any one have this prob b4?
