whats wrong with my jeep need answer asap (Jeep won't idle after jump start)
I tried starting my jeep, I haven't done so in a few months. It won't start lights won't even turn on. I figure the battery is dead. I try jumping it, get it start and it won't idle just dies. What's wrong?

I seem to remember someone stating that if the battery is completely dead, the Jeep will not run...hopefully someone with this knowledge will chime in here.

I jumped it though, so the battery needs to charge a little longer?

just keep the revs up for a few minutes and it will stay running after that
it will continue to do this for the next few times you start it
but once you are starting it regularly again it will go away
but a vechile siting this long should get new oil and plugs

The alt. needs some juice to produce a charge, it has to be excited to work(really)
1st Make sure the is water/acid to the proper level in Bat.
2nd Remove and clean all Bat connections.
3rd Charge Bat. overnight if possible.
4th If unable to charge, leave jumpers on for a while, while running both vehicles, giving time to store juice in the discharged Bat.
Check output of Alt. Should be somewhere in the range of 13.5 - 14.2 volts

Nope, very common misconception. The alternator, as has been stated, needs voltage from the battery to produce current needed to run the rig.
That's another reason why all the manual trans owners are wrong when they state one of the reasons to own a manual is so you can bumpstart if your battery dies. If the battery is dead, you can drag it around the block with another vehicle and it won't run until there's enough juice in the battery to keep it going.
