Chris, another way to check is to remove each fuse and place the multimeter probes (with your meter still in the amp reading mode) across each fuse holder and check which one is drawing the amps.
One guess would be the glove box light? remove the globe and check. Or if the box has been closed for a while, open the glovebox and check if the globe and holder is very hot meaning its been on for a while. Then try unplugging the alternator, coil etc..
