I dont want to make this to broad. but my wife was driving my xj yesterday. no issue's. no funny noises. parked it. went inside the shoppette, came out one click. no start. no voltage. headlights wont turn on, no power at all. Tried getting a jump from a 4runner. nothing. starter didn't even try. but no aux power in any key position. im going to try a borrowed full charged battery. and check the terminal's in the morning. was just hoping for some more input and hot ticket area's to check. thanks in advance gentleman.
Clicking and not starting is a lack of voltage. Either a bad battery or more likely, bad connections. Naturally you should check all the fuses in both fuse boxes.
Begin with basic trouble shooting of the start and charge systems. Remove, clean, and firmly reconnect all the wires and cables to the battery, starter, and alternator. Look for corroded or damaged cables or connectors and replace as needed. Do the same for the grounding wires from the starter to engine block, and from the battery and engine to the Jeep's frame/body. You must remove, scrape, and clean until shiny, the cable/wire ends, and whatever they bolt to. Jeeps do not tolerate low voltage, bad connections, or poor grounds.

Put a voltmeter on the battery and see what it shows. Even if it shows 12V pull the light switch and see if it goes to 0. Had this happen to my Triumph battery, and last week the jeep made a pop and everything went off. In both cases the initial reading was 12V. But you could could put the tiniest load on the battery and it went to nothing.
You need at least a good 12.6 - 12.7 V to be able to start it, nothing less. It's very odd that you did not get warning signs and have no power at all. This is too weird. Could be one of the main fuse, or the ignition switch or something. If the battery reads good then the problem's elsewhere.
thanks for reply's all. I am going to go to the gas station and check it out after work. at least it's on base so it's fairly safe. ill definitely let everyone know what i deduct from my troubleshooting today
so i ended up removing the positive cable from the battery. reseating the cable's in the coupling and voila. fired up. it was finger tight. no idea how that happened. going to go to auto zone to get the alt and battery tested though to see if maybe i just got lucky with the start
Its amazing how little it takes for nothing to work with the battery connections. Clean and tight is important!!
