I have a '93 940. If I let it sit without running it for more than 3 days,
the battery is dead. Does anyone have any idea where I might look? I know
the doors are closed and the dome light goes off; I know the glove box door
is closed.

Thanks.
 
you could start by placing an ammeter in one of the batt lines to see the
current drain switch off the interior lamp and then one at a time pull each
fuse and see when the current drops to zero then check the items operating
on that circuit. if it isn't covered by the fuses then disconnect the
alternator as these sometimes drain the batt if a diode is shorted but
usually much quicker
