Saab Repair: 99 Saab 9.5 electrical question, amp meter, drain source

Question
Hi
My son has a 99 Saab 9.5 and something is draing the battery in it(short?) Is there a method for locating this drain source?  We put a new battery in it and the next morning it was dead again.

Answer
You need to hook up an amp-meter and read the current draw. It should drop below 20 mA after 20 minutes. I f not the you can start removing fuses until the draw goes away, then you know which circuit is causing the draw and you can proceed from there.
