go to the fuse box and do the voltmeter test on each circuit one at a time. all you need to do is pull a fuse and test the 2 terminals that the fuse came from ..... if no votage is passing through, put the fuse back and test the next one .... eventually you will track down the circuit/circuits that were probably draining your battery.
