Some auto parts stores will check it off the vehicle for free
A new battery or one that tested good is in the vehicle and the car is still losing power. the alternator is what charges the battery while the vehicle is operating.
I use a Digital Volt/ohm meter and test the output of the alternator at the battery or at the main output terminal of the alt. If I'm still in doubt i pull the alt and have it tested at Autozone for free.
If the light remains on then the system still isn't charging as it should. Check the plug on the alternator and also that the wires to the alt have a good connection.
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.
same problem what the answer
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.
check for proper belt tension, check all of your connections from the alternator and the ones on the batteryif everything check out have the battery tested, if none of this works feel free to e-mail me
your alternator is either week in volts. Use a volt tester. or alternator is now working. replace it. I had same porblem with three batterys to test the alternator turn car on let run on idle and disconnect the positive car should still be running if it shuts off first check all wires on alternator if still connected then alternator is bad TIME TO REPLACE IT.
The charging warning light should automatically reset if the battery is disconnected. Check the battery cables and ensure they are properly connected. Also check the alternator connections. If the light is still on there may be a problem with the new alternator.
An alternator does not need a gauge to work. It is used to monitor the output of the alternator.
Are you certain that the alternator is connected properly? Is the keyswitch working properly? Does your alternator have an internal or external regulator. How old is the battery? If it's about 3 years old, especially if you live where you have a real winter, about 3 years is all you can expect out of a battery, and it will just collapse and die. Auto Zone will check your battery out for free if you take it in. I wouldn;t have just replaced the alternator unless I knew that was the problem. Phil
