Volvo: Key Off Battery Drain?, digital multimeter, negative cable

Question
Had my battery charged and tested and it passed...when my '95 850 turbo sits for more than 2 days w/o starting, it won't start up (can sit for a day and it still starts up)...after 2 days, it tries to, but just doesn't have enough juice...jump start it and it fires right up...drive it around for a bit, turn it off, and if fires right back up, so I don't think it's the charging system...what's the regular amount of milliamp drain with the key off/for the KAM on these?  should I hook up a digital multimeter to the battery and start pulling fuses/relays or do you know off hand what this might be?  Thanks for any help.

Answer
Charles,
Most likely there is a drain on the battery as the car sits. Something like a glove box light or door check light. That will take some testing and patients to find. Finding a draw will take time, it tends to be a tedious job. A test light between the negative cable and the negative post touching it together every few seconds while pulling fuse and or bulbs. If the light is lit even dimly there is a draw.
