Post the running and not running voltage that you read across the battery.
Next, to determine what - and how much - is drawing excessive off current, you have to get the ammeter inline with the battery. That means with the trunk and hood open, you have to take car of dealing with the latch front and rear so no lights are on. Measure current after car goes into
shutdown. Should be less than 100 ma after a few minutes. Like the other user said, you're looking at likely over an amp. Then start pulling fuses one at a time until current drops to nearly nothing. After each is verified not it, drop it back in place without pushing so you don't mix them up.
