When measuring parasitic draw, the car needs to be "prepared" beforehand. It
can take up to 45 minutes for all modules to "go to sleep". Something as
simple as opening a door can wake a module up.
Preferred method... open all the doors and trip the latches so that the GEM
"sees" them as being closed. Make your connections with your ampmeter and
leave the car for at least 45 minutes. When you pull fuses, start with the
CJB (underdash fuse panel)... Keep track - once a fuse is removed - do not
reinstall it until the process is finished. If the fuse is reinstalled too
early, it can wake a module up and skew your test results....
Jim,
Thanks for the info. Parasitic draw was closer to 10 mA. One thing I
did notice was that the battery voltage had dropped overnight. The last
time I measured the voltage on the battery yesterday, it 12.8v and I
left the negative terminal disconnected. This morning it was 10.6v.

If the battery is self-discharging without being fully hooked up (the neg
was disconnected you indicated) then it's time for a new battery I would
think...

Bad cell. (cell voltage is about 2.1v so any time you see multiples of
that magic number, you know what it is) Time to replace the battery.
Probably what happened is one of the cells has disintegrated inside so
that almost no active material is left in the electrolyte.

All,
Thanks for the help and ideas. It was the battery.
