Wiring diagram for a 2000 Jeep Cherokee Sport

The one in the Haynes manual might be close enough, because you have such a gross problem. Check voltage on each of the fuses... check voltage on the computer... then check voltage at the ignition switch. If power isn't making it down the line, the ignition switch is a popular offender.

Scott,

Thanks for your reply... We have tried all that, there is no voltage to any of the fuses or computer, there is voltage to the ignition switch, the motor cranks over, but that is all... We have taken out the entire instrument cluster hoping to find a loose wire or something, but no such luck... All the fuses are good, we took them all out and replaced them all, same thing... Will try to find a Haynes manual, but since I live on a small Caribbean island, going to my local auto shop/store is sort of out of the question unless I want to travel to the main island of Puerto Rico for it.

I would be thinking fuse link wire.

These are 8" wires with a loop on one end and a fat rubber tube crimp connection on the other end where they joint the harness. If you follow the main battery positive cable, it will end on a bolt at the power distribution center or starter relay on the fender. At this bolt you will find the fuse links.

These protect the harness pieces in case of a short and are usually the first thing cooked if someone tries to boost it and gets the cables wrong so it sparks.

You also should have a mesh body ground strap that runs from the rear of the engine to the firewall. When this breaks or corrodes, the computer doesn't get a power circuit to turn on.

You should post this over on rec.autos.makers.jeep+willys for a lot more opinions and likely even a link to the wiring diagram.
