MY battery dies overnight, i charge the battery in after noon, and when i live my car over night, by the morning battery is dead already. Before, my battery would die pretty quick if i leave radio on. But this time the battery just dies over night, and its been happing 4 days in a row. I recently changed serpentine belt, maybe there something i did wrong, but im not sure. My own theory is that maybe its too cold, and im in need of a new battery or power alternator. Also people been suggesting to check the whole electrical system, is there anyway i can do it my self, to know whether my battery is bad or power alternator. thnx
i will do try it tommorow and let you know. I suspect maybe its fuses because, shortly i replace few fuses because the other was burned, those burned fuses caused my tail lights, dash board light and interior lights to go off. I also put new interior bulbs, ordered them from autohauz. Maybe if its fuses, then what do i do, because those fuses i got from bmw dealer. Also do you know how to check the power alt. and battery correctly, what numbers should i look for?
so i think i found the problem, i recharge the battery again today, and started the car. i close all doors, and turned of all the lights, but then i decided to check trunk from a inside of a car, and i saw bulb still on, so for now i took it of, any suggestions why the bulb does not turn off in a trunk?
