WOW!! the exact same thing happened to me but the difference is i was on a 30 road doing 60, i think like a week after i got the car, so like we all do when we just got the car, i was driving like a maniac, the only difference is my accel pedal was floored and i didnt know what to do, so the car was being redlined and over-reving like a biatch! so i switched into neutral , then pulled over then switched the engine off. before i knew it my car wasnt taking electric charge and everything started dying. when i popped the hood, my altonator belt snapped.
Thank God your good anyway
