Re: dead battery
Welcome to the forum. Check your battery and alternator charging. The battery voltage should be 12.8 or so with the engine off. The voltage for the alternator with the engine running should be 13.8 to 14.3. A way to check what is draining your battery is to put a test light or a voltmeter between the positive terminal of the batttery and the positive cable. Make sure all the doors are shut and start pulling fuses one by one. The test light or voltmeter will go off when you pull the fuse that is draining the battery. Once you know what it is you can begin to eliminate it. If you know which system is draining it but not what it is specifically, you can post again here and someone with a schematic can tell you.
