Question about Cars & Trucks
New alternator and battery
Faulty new alternator or wiring to battery is causing too much resistance to the battery to give it enough charge to re-charge it. Take the car to Autozone or Orielys and get them to test both the battery and alternator for free. If both pass, then it's most likely the cables from the battery/alternator need to be checked.

May I suggest that you drive your car to one of the major auto stores and they can and will check your alternator for you to make sure it is good/bad.These places like AutoZone do this all the time. They do not charge for the check out. (Of course they are hoping that if you need a part you will buy it from them.
One other suggestion. If you do need a new alternator, get a rebuilt one. It is cheaper and most always comes with a warranty.
Hope this helps Good luck Loringh PS please take a moment to give me a rating

SOURCE: Car won't stay running.
alternator does not hold a charge it simply charges the battery by unhooking the battery you are taking all voltage from computer and car will not run the proper way to test your alternator is use a multimeter and check voltage at battery while car is running if you have 13-14 volts it should be fine.

Check all your fuses if you had a system failure it could have blown a fuse. I am not sure on your vehicle where the fuse is in the car or under the hood it could also have a relay. You can check your alternator by checking the voltage at the back of the alternator where the big wire bolts on. You should have 14+ volts at the alternator.

Check the main power fuse that goes to the alternator output. if the alternator went out it could have burnt this fuse also.
