I replaced my instrument cluster with one from a SR5 pickup. The voltage guage is stuck at 18V. I'm reading 14.6 volts at the battery with the truck running. The FSM trouleshooting say to check the inline fuse or replace the guage. Where would I find this inline fuse? Or or they just talking about the fuse to the instrument panel? My truck is an 88 4x4 with 22 REI motor and 5-speed. I do have a correct five speed instrument panel. Any help on this? Thanks, Roy

Hand me that crowbar.
