Saturn Repair: 1995 Saturn clicks and dies, using a multimeter, mv output

Question
Battery seems to be discharging overnight, a jump will start engine and will idle.  Placing in gear car will die in 20 feet, requiring another jump.
Help me Obie-Wan.  You're the only one who can.


Answer
Nick,
You are talking about a "parasitic load".  The only way to diagnose one of those is to test the mV (milivolt) output of your battery.  You do this by using a multimeter and systematically removing circuits (removing fuses) from the equation.  One by one you should see the mV output dropping.  When you have found your biggest drop, you have found the problem.  It's not an easy process, and surely time consuming.  If you need more help, let me know and I can walk you through most of it.  Hope this helps.
