You need to check for an electrical draw. Refer to our homepage under the DIY section for directions. If you extablish there is a draw, remove one fuse at a time to determine the circuit that is causing the draw. Keep in mind, even though your alternator is charging, a bad diode in it could allow power to pass to ground and kill the battery.
