Ok so my car battery dies after a day of just sitting. I tested the battery and It's at 11-12 volts after a charge. I test the battery while the car is running and it's at 14.5 volts. So my battery is good and so is my alternator. My question is how the hell do I track down what's draining power. Dude told me to test all the fuses individually when the car is off but even then most are giving me a 12v reading. Any help?
