Haha good suggestion public. May be his flux capicitor stopped fluxing?
Brain Dump: I would buy a voltmeter gauge, install it, and watch whats happening. You should be running 12+ volts. If you're running anything lower theres a drain on your system. Do you have a speaker systems with an amp/large subwoofers? Normal batteries aren't designed for the large fast drain a pounding amplifier will apply to it. (Thats why those deep cycle red top optima batteries are suggested) An easy way to test the alternator is to get the car running, then disconnect the positive on the battery. If the car cuts off, the alternator isn't working. A couple of other things I would do is check to make sure all wires have good contact and aren't shorting out. From the sounds of it, do you have electric window motors? May be one is stuck on? Also, may be you could charge your battery, to where it will start the car. Shut it off, disconnect the battery, let it sit overnight. In the morning, re-connect the battery and see if you can start it. Just a couple of suggestions on my thoughts and how I would tackle it. Let us know how goes... good luck
