This is not normal.  Either your battery is bad or something is sucking
way too much current.  Do the meter test as recommended; you might want
to start with it on a high current range just in case, so you don't
overload the meter if there is a large current.
  I just did the same thing on a J**p yesterday.  It has a Clarion CD
player with clock and preset memory.  The current being used from the
battery was about 7 milliamps (7 thousandths of an amp).  When I opened
the door, the dome light used almost 1 amp.

good luck,
