Well if an electrical short is your problem, there is a test that anyone can do to find it. All you need is a multi-meter ($15.00 to $20.00 or so at AutoZone). Disconnect one of the battery cables from the battery. Take your multi-meter, turn it on, and set to twenty volts DC. Take one lead and connect it to the newly disconnected battery cable, and connect the other lead to the battery post. You may have to MacGyver it to keep the leads connected (maybe use tape or something). You should see some sort of reading. Now start unplugging fuses, one at a time, until you see a significant drop in the meters reading. You have now identified the circuit. If the car has any aftermarket electronics (like a radio, for example), then start with checking that.
This is the multimeter that I have: http://www.sears.com/craftsman-multimeter-digital-with-8-functions-and-20/p-03482141000P?plpSellerId=Sears&prdNo=1&blockNo=1&blockType=G1
Let us know which fuse it was and I will personally look up what is on that circuit.
