right! that approach makes much more sense. I had a weird reading, I would read the amp draw, it would climb to .68amps, then trickle down to .03. and it would stay there. I would remove the meter, wait 20 seconds, and it would do it all over again.

either way, i have isolated the trouble makers. With almost ninga like skills. I only tested 3 other fuses besides the bad ones.. i know...awesome.

fuse 21, amp draw went from .03 to .01

fuse 27 went from .01 to .00...

fuse 21: glovebox light
ignition key/seat belt warning
interior lights
radio memory
trunk lights
radio memory
active check control
service interval indicator
fuel delivery
tachometer/fuel economy gauge ..... (mine swings back and forth)
digital clock
multi function clock.

Fuse 27-30 (fuse 30 was fine)
interior lights
central locking
radio amp
