Battery runs down overnight the battery is new

have the battery load tested first
then have the alternator and voltage regulator check for correct operation by an accredited auto electrician

Sounds like something is running your battery down at night. Have you added any new equipment to vehicle? Something is pulling ampage.

if you installed a new battery as well as a new alternator, it should not go dead overnight. if you have a short in the vehicle that will drain a new battery that rapidly, the cable would have been melted already. although, dome lights do have a tendency to drain batteries, but not overnight. use a multimeter to check the battery voltage while the motor is running. it should read above 13 volts DC signifying that the alternator is indeed charging the battery.

Is the battery new? Does it start fine until it sits overnight? Have you checked the alternator? Does the battery have sufficient cold cranking amps,dead cell? Is an interior light staying on, glove box light? Do you have an aftermarket stereo with an amp?

get the battery cheaked most motor shops will do this free but if battery ok could be a short or alternator not charging

A battery that runs down overnight usually means a bad battery cell...you can sometimes see a swelling of the battery case as the cells are aging...if battery is new...a rare starter short can cause the battery to drain overnight...When running, have the battery tested before you are stranded...Hope this helps.

The weak battery can cause this. Remove battery, trickle charge overnight, and have tested by a reputable garage, out of vehicle. My bet is that you have a very weak battery, and Chrysler products will have all sorts of alarm problems if the battery can't hold 12 volts overnight.

the most common cause of a battery running down can be traced to lights that are on when the ca r sits overnight, check your glove box and make sure that the light inside is not staying on when you close the door,check the light switch to make sure it is working properly and turning off when the glove box door is closed.

Pull any fuses marked stereo/radio and see if that helps. If insurance is involved, take it where new stereo getting installed & have them do it for you if your stumped.
