I have a 2000 4.0 sport. I have 12.73 volts at the battery. It will not crank, there is not even a click. With the key in the ignition, and the door open, it does not beep as it should. Nothing inside works. No power windows, door locks, radio, interior lights, headlights.

--it does nothing. turn key, nothing, dead...I checked 3 fuses---ign acc/run - ign run/start - battery acc--all good

If your battery's voltage is stable, it's not that you're losing voltage. If that were the case, the battery would be losing voltage while the XJ sat. I would check that your battery terminals are clean and use a terminal brush JIC. If you don't have one, they're really cheap and very useful. Then check that the wires going to the battery have a good connection. I had bare stranded wires going into the connectors and it was causing an intermittent complete loss of power. I added a couple eye terminals and my problems disappeared. If all of that checks out, it's pretty likely that you have a ground issue. Start checking the major grounds and let us know what you find out.

found it--bad ground wire at the battery--cut the end off the corroded wire and put a new terminal on. Thanks.
