Default 91 Civic slow battery drain.

Hi guys, I've got a slow drain on one of my fuses so i've been trying to figure out where the short circuit is.

It's on a 15a or 20a fuse that runs the horn and the stop lights, so i unplugged the horn and every bulb on the tail lights, but still haven't been able to locate the slow drain.

I looked for wiring diagrams on google, but couldn't find anything.

If someone could tell me what other components are ran from that fuse, that would help greatly.

Any help would be appreciated, thanks.

ZHow did you get to the conclusion it was that one? I have a slow drain of my own.

sure it's a fuse or wiring? could just be a bad alternator.
then again if you have speaker wires to an amp or something they could be grounding out also.

I tested the amps coming out of the fuse port with a multi-tool and it was pulling .7 amps with the key off.

The leak is at a continuous .7 amps so i ruled out bumping wires. The car doesn't have a radio either. Is there anything else that runs on the "Horn Stop" fuse?
