Mysterious Electrical Drain 850 1997

Hello all-

Wife's car 100k, nicely maintained. Three weeks ago, she calls: "Car's dead". Rush home, jump car, give her my 850, drive hers to drop off the kid and then on to work. Started fine at daycare. Sat from 9AM to 5PM - started fine in the parking lot. Got home - cleaned corrosion off ground terminal. Assumed that was the issue & all is good.

Next day: Get another call from the wife: "Car's dead again". Crap. She calls AAA and they jump it off. She drives to Pep Boys and they test alternator (say it's OK) and install new battery. This was Thursday. Drove the car through the weekend, parked it on Sunday evening. Monday morning: You guessed it - Dead again.

I have done all the looking around I can do. I did my own alternator test under load/no load with a simple digital voltmeter. I tried to use that as an ammeter in series with the battery while pulling fuses to see if I could find the circuit with the drain, but I couldn't get my ammeter to function where that would work out.

The interior light overhead console has been shot (mechanical failure of button) for a few months now and I just bought a used one on eBay, but I don't think that's causing the problem. No lights (glovebox, interior, etc.) seem to be on after checking at night where I could see better.

Any help would be GREATLY appreciate before I swallow my pride and take it to a local independent (I do all my own work and don't even have a mechanic).

Thanks to all in advance!
