I have had a problem with a car, 1994 Chevy Cavalier. I was driving my mom to work and the battery acted funky, the car started to chug and eventually it died on the side of the road. We got a mechanic to get a starter pack on it and lo and behold, it jumps up instantly with no problems. We take it there, he checks the alternator, battery (Both of which are fully charged) and the lights aren't even on in the car anymore. He couldn't find a problem, he even looked for loose connections. Any ideas?
