Current draw #10 fuse circuit

My battery kept going dead. I isolated the current draw to the #10 fuse circuit.( Powers the chime module,electronic brake components,and other components I cant recall now) I have removed the actual chime and the and the current draw still exists. Is there another chime "module" somewhere? If so where is it? Has anyone had experience with this,and found a problem with any of the components in this circuit? Thanks for any help. Frank.

The theft deterrent module, seat belt/key warning module, radio, and EBCM (anti-lock brake) module are all fed from that fuse.

Anti_theft is a common unit for this problem. They can short without causing any other symptom.
