Loose or corroded connections or the battery has a dead cell and will not accept a charge and must be replaced.
You can have the alternator tested free of charge at just about any major auto parts store. By the way, a bad alternator will not "discharge" a battery - the alternator's function is to provide the charge to the battery. If the alternator is faulty, then it is not providing the charge necessary to keep other components from discharging the battery. I had the alternator tested and it was charging. If the alternator has a bad diode, it will discharge the battery. I replaced the alternator and everything is fine.
put in new alternator but it will not charge battery. alternator was tested and found to be good. why wont it charge the battery?
Have the alternator tested.
Get your alternator tested at autozone,its free,and check your battery too.
That is typically caused by a faulty alternator. Have the alternator tested; the light is indicating that the alternator is not providing a charge to the battery.
Sounds to be alternator. Take somewhere to have the charging system tested.
Either the battery is bad and won't accept a charge or the alternator is not putting a charge into the battery. Have the battery tested. You can hook up an inexpensive volt meter to the battery while the car is running. You should see from 13.5 to 14.5 volts if the alternator is working properly. If it is less than 13.5 volts then the alternator is not charging.
the battery could have a dead cell, this could cause it to not charge. Have the battery tested to be sure.
bad alternator. i had the same problem. My old battery seemed dead so i replaced it with a new one. the new one was fine for a couple of days then the battery charge light came on again. i had the alternator tested it was done for. ...or it could be bad connections or wire. have it tested.
Your battery is not keeping a charge, or your alternator is going out. I would have them both tested. Autozone or Oreilly.
Has the battery been tested, does the alternator on the Durango try to charge?... If the truck runs with the battery but the battery doesn't take or hold a charge, it has to be the battery being bad or extremely bad terminals so that the charge can't reach the battery. Age of the battery doesn't matter, a fairly new one can still go bad.
Repair or Replace or have the alternator tested off the vehical to try and isolate the trouble. ANSWER Check your wiring including your battery cables. Sometimes cables can look okay but be corroded inside the insulation, especially the ground strap.
