91'EscortGTdeadshort

My car has a dead short somewhere. I have continuity between the pos+ batt cable and the block. When I pull the 10Amp. ROOM fuse the needle on my multimeter drops but not to zero. The ROOM fuse goes to several things including three things I cant locate. The TWS unit, EEC module,or the EAT module. Can someone please help me with this? Does anyone have any ideas?

this is one thin you probly have to check evry wire on.. hope you dont got power locks or windows...
