Fixed an electrical problem on the S14 yesterday. There was a 3.0A draw on the battery, so I had to leave it disconnected when I wasn't driving it. After using a multimeter set to amps connected in series between the negative battery cable and the battery negative terminal, and pulling fuses one by one, I found out the horn fuse in the engine bay was the culprit. Horn doesn't work, so I just left the fuse out.
