Wont start! Need help!

Ok, so was on break from work today, drove my 02 TJ home to get some food. I head out to go back, get in the jeep turn the key and *click* car doesnt start, gauges on the dash go back and forth then the alarm starts going off. First beeping at intervals, then weird ones, then regular, and alternates. Went under the hood, loosened the the terminal on the battery and moved it a bit and the alarm shut off. Tried starting 3 times, same thing each time. Any ideas?! Don't wanna be jeepless this weekend, its really nice out. Thanks

Bad battery connection or corrosion.
Loose ground wire.
Battery is not fully charged.

I'd start with those...

Same thing happened to me JUly 4. Get yourself a battery. The guages jumping are your jeep's way of self=diagnosing. Clean the terminals and you should be good to go. Same scenario, Drove it about 30 miles shut it off. Got back in 30 minutes later and nothing but a click. The guages were jumping even when I had the keys out of the ignition.

good one..

battery sounds like the issue, i had similar problem with mine as well, also a good idea to switch to gold terminals if possible. be sure to spray the terminals and battery posts with that red spary protectant stuff.. not sure what brand is used, but your local auto store will have it. you can check the battery with a meter, be sure it reads 12 volts, also check your alt while the Jeep is running and be sure your getting at least 13 or better back. also check ground wire.

good luck

Remove both battery post connectors and thoroughly clean/brush them, then reinstall the connectors and tighten them firmly. Don't do anything else before doing this. Loose/corroded/dirty battery connections are the usual cause of problems like yours. If after doing that you still have problems, have your battery "load tested" which will give its overall health.

Don't replace the battery before doing all of this first.
When you have a choice, buy American.

+1 battery.

That's what mine did when the battery was dead.

At the auto stores they have these little battery changing kits for like $2. It includes crap to clean the connections.
