jeep want idle after jump start

i have a 2000 jeep wrangler that has a after market alarm that I don't use. I still have the original battery in it. I have left my headlight on and when I received a jump now it will not idle any ideas

When a battery is run down you shouldn't rely on the alternator to recharge it. Recharge the battery with a charger, that may help things.

If the battery is very flat it will not run after a jump start. You need to keep the revs high for a few minutes to get some charge into the battery before it will idle on it's own.. I've done this with a hand throttle before, if you don't have a hand throttle you need to keep your foot on the accelerator, and someone else can disconnect the jumper cables.

You might have a shorted cell in the battery. Get it tested and replaced if neccessary.

Yes. After a jump your Jeep will not idle. Keep the revs up a little bit, have someone else disconnect the cables and go for a 5-10 minute drive on an open road. Your problem will be solved.
