What all does fuse 23 (10 Amps) under the hood control? I have a battery drain that does not occur if I remove this fuse. I know it controls the stereo (doesn't come on anymore if fuse is removed) and maybe the passenger dome lights? Also, the tachometer did not go back to zero when I turned the vehicle off but did so when I turned the ignition key to on (but not all the way to start). Seems like there could be a better label than "Back Up" (the back up lights still come on when transmission is put into reverse).
