I drove my 98 xj home yesterday from work and this morning got in it and it done nothing. No dome light, completely dead. I hooked up the battery charger to it and it is still completely dead. I checked fuses under the hood. I wiggled all the wires and nothing happens. It's a 4.0 with just under 200k..I'm confused. Any info would be great

 

check your connections to the battery.

 

Try jump starting with another actor at least see if the light come on. If they do then your battery is done. If not then it's a connection problem

 

also check you main positive leads going to your battery if they look any corroded they need to be replaced.

 

You mean, you charged the battery and it is (still) dead?
In that case, ur up for a new battery.

Do you have a voltmeter? If not, get one for not too many $$ (if only for future issues) and hook it up to your battery. Then you will know where to go from.
