1G Big battery drain that isn't alternator

[Vegas Smith]

Hello folks, I have a 93 AWD that will be almost dead a day or two after I leave it sitting in the garage. I have confirmed that the battery is good and takes a charge. I'm getting around a 2amp current on the battery when the car is off.

I unhooked the alternator power and signal and the battery still reads 1.98 amps. I also connected the alternator directly and still got the same reading. Therefore, I don't think the alternator is the cause.

The draw goes away when I remove 80a alternator relay or 40a battery relay.I traced the hot to the "room" fuse in the cabin. remove i remove the room fuse the draw goes down to 1 amp. Does anyone know what would drain a battery in a day under this fuse? I know there are a lot of things but some narrowing down of most likely suspects would be nice. Thanks.

edit: my mpi relay under the stereo and my isc buy buzz when I connect the battery.

Use your volt meter and just start teaching the power draw and randomly unhooking things until you find it. My 1g had a 1.4 amp draw i traced to some bad wiring to a door switch for the dome lights, and some stereo stuff the previous owner installed

Trunk light on???? It's one of those things that you don't see everyday usually.

I figured out the isc drivers on the ecu burned out and were causing a draw through the isc and mpi relay. Thanks for the responses though.
