Not that unusual. Chrysler builds a pretty crappy charging system. If the battery gets too low, the things will not idle. Its also NOT a great idea to charge a dead battery with the alternator. Yes people have done it for years, but then smoking has been around awhile too. Either drive the thing to charge the battery, or take it off and run it down to the Autovancerielly store for a free quick charge.
Then see what it does.
"The alternator generates all the power needed to fully charge the battery IF the alternator does not overheat and fail. A dead battery will draw a very high load and stress the alternator to its maximum output limits and so I suggest you don’t run the headlights or other high amp accessories for at least the first 45-50 minutes of driving (charging). It will take (for example) a 70 amp alternator 0.85 hours (51 minutes) to fully charge a dead 60 amp hour range battery. I don’t know what your battery amp hour rating is or what the output amp rating of your alternator is but I assume your battery and alternator are suitably mated and so 45 to 50 minutes of driving/charging will not overload the alternator output capabilities as long as you do not add more stress on the alternator by running the headlights or other high amp accessories during that time."
