Question about 2000 Ford Mustang
With everythign off and doors closed you should see about 25 milliAmps (.025 Amps), im guessing wiht it killing your battery in about a week, you wil see a draw anywhere from 50-60 milliAmps.
Do you have any aftermarket products added in? Remote starter? Alarm? Satellite Radio? GPS?
There is also a slim chance, even though its new, that there could be an internal short IN the battery, that will not be detectable by use of a multimeter.
its unfortunate that there are many reasons why the battery could be draining in a week, but the suggestions from TimtheStick's info is a great place to start.

You have a draw! First, get a digital multi-meter. Next, shut the ignition and all systems to the off position. Next, disconnect the negative battery terminal. Using the "amp" feature of your multimeter hook a pair of aligator clips to the negative battery terminal first, then to the negative battery cable in the car. You should immediately begin to read "amperage". If you are reading a minute (say around 7 to 10 mili-amps), there is no issue. If you are reading in the .1 "amps" or range (even a little below that), you have a signifigant draw. If you're pulling about .1 amps or higher, start unplugging fuses untill the draw goes away. You have found the system pulling the draw! Diagnose from there! the Stick

You may have something draining the battery like a radio alarm or an active light that may be on all the time. If you suspect the battery check it for fluids under the battery caps but be careful there is acid under there. If you have liquid under the caps that is a good sign just have the battery fully charged and the cells checked if they are good then you have a drain in something electrical in your vehicle.
