Are you reading from the positive battery post to chassis ground with the
ohm meter? That's not a meaningful reading, since you are putting the 12
volts in series with whatever your ohm meter has internally. Actually, if
this is the connection you are using, you are making some kind of across the
battery itself, and not looking at the circuits that could be draining the
battery.

Do what others have suggested: The handiest way to measure is to disconnect
the ground cable and insert a current range of your VOM. You should see
any current being supplied by the battery. Then disconnect the positive
battery cable and the current should drop to zero. That will tell you that
you are on the right track. Then pull fuses or disconnect wires until it
drops to zero again. That will be the *aha* moment.
