Wiring problem

2000 TJ .... the tach, the gauges and the radio does not work, they seemed to work fine yesterday....I checked the fuses, they all have incoming power and the fuses checked out as well, I believe from the fuse panel, the power goes through the ignition switch and then out to the components..would this be a common wire or does the gauge cluster and the radio have separate terminals in the ignition switch? Can't seem to find the color codes for the switch....any help appreciated.

Look at fuse 25 in the Power Distribution Center. It's the black fuse and relay box in front of the battery.

IOD = Ignition Off Draw... IIRC

Yes, Ignition Off Draw. It can be removed if the jeep is not being used for an extended period to reduce the battery drain. Besides the cluster & radio it also powers the underhood light, the courtesy & dome lights & one power wire to the OBDII data link connector. All the wire from that fuse are pink/white. The ignition switch has nothing to do with this circuit.

Thanks folks for helping me out....I caused the problem myself, I was working under the hood and hooked the underhood light wiring with a wrench.. this cause the IOD fuse to blow. mended the wire, replaced the fuse and all checked out just fine. Again.. Thanks to all, denny472
