battery drain

My daughter's 1993 900 NA Sedan has a battery drain that I just can't seem to locate. If it sits overnight the battery goes dead. Yesterday I charged the battery and did not hook the negative cable back up and this morning the battery still had a full charge. I also had a load test done on both battery and alternator and both checked out good.
I hooked a test light up between the negative battery cable and the negative battery terminal (again, cable not hooked to battery). The test light blinks on and off while the timer for the interior door light is energized. As soon as the 15 seconds or so elapses for the relay, the test light goes off and the interior lights also go off. The trunk light is turned off (it works as it should) and the radio antenna is disconnected.
I've pulled the fuses under the hood and IIRC, the fuse for the clock was the only one that showed current with the key off.
I don't have a DVM (broken) and I'm finding my old sweeping-dial type meter is worthless.
Any ideas on where to look?
