My 1983 dodge ram charger died the other day going down the road so i bought a brand new battery and a alternator . thinking that this would fix the problem. but the next day it drove until the battery lost charge and it wont fire back up unless i give it a jump and iv'e put two brand new batteries on the truck and a battery. what could be causing the truck to not keep a charge?
The voltage regulator isn't being turned on when it is need
The challenge it to look at wiring diagrams & see what controls it
Jumping a dead battery is a dangerous thing to do
Batteries require they be fully charged before being put
back into service- to continue any testing
If you even jump a car made in the last decade,
you may smoke the electronics
On newer cars you disconnect the battery, to charge
it alone from the vehicles systems
Here's a link,enlarge fig. 17,see the fusible links,check them out,may be burnt.Here's a description of the fusible link.

Regulator in alternator obviously faulty, have it bench tested & fixed or replace alternator, and cure your problem.

Any time the computer loses power it has to go threw a set of things to Learn how to run the car, it must go threw relearning process sometimes they never set all flags because you don't drive in conditions to set a flag, for example if you are in the desert and never drive up a hill like in Colorado then you would never meet that flag requirement, as for the low voltage it seems that the ASD shorts out on these rigs and sets the codes so you have to do a pin out of the computer to see if you have a bad ground a bad asd or asd relay and you would have to charge your battery to full capacity and do a voltage test and a load test on the battery and then see if the alternator is putting out.. Check the battery and charging system first.

some times the alternator has certain parts in it that read okay but their is something wrong with it,yes lights are draining your battery check your ground connections

It sounds like you have a bad PCM (computer). The computer controls the charging system as well as the idle speed. For this year of Durango this is the most likely cause. To test it fully you will need a wiring diagram, meter and a scanner would be a big help.
