From what I'm gathering you probably need to replace the alternator.
so your car in turned on but not running and your 12V battery is draining, sounds normal to me. even with the stereo off and AC off you will have something draining your battery
I only want to be faster than the guy next to me.
I think maybe alternator belt are the problem
