Loose wires to the headlights or fuse panel.

Battery wont make an engine die only bad alternator or missing belt. check both belt and alt output.

Hello, If you have not put on a Serpetine belt in some time, then your belt has probably stretched to the point where it does not grip the pulleys good. You can also have a weak Tensioner pulley as well.

You need to replace both the belt and the Tensioner pulley to keep the Alternator pulley tight so nothing loses its, grip. Sometimes you will not hear a squeal from the belt, and the dash light will flicker.

Check on NHTSA.com, Service Bulletin 012113 and see if you are in the included group of cars with ignition switch problems.
If the batteries were destroyed, you have a bigger problem than just a switch. If the batteries were just rundown, the switch was a possibility. The engine quitting can be from the ignition switch.
The technician should have been able to get a reading from your car to show the same thing as your battery light. He should have done a wiggle test.

If the battery light comes on at high speed, the belt may be slipping from a weak tensioner or a stretched belt. Also check your starter connections for loose ends and corrosion.

HAVE BATTERY CHECKED IT COULD BE BAD OR HAVE A DEAD CELL IN IT.ALSO CHECK ALTERNATOR OUT PUT.IT SHOULD BE 13.5 TO 14.5 VOLTS. IF NOT THE ALTERNATOR ALREADY BEEN REPLACED YOU HAVE BLOWN FUSE OR FUSELINK.OR THE ALTERNATOR WIRES COULD BE DAMAGED OR BROKE.MAKE SURE YOUR ALTERNATOR BELT NOT SLIPPING.IF ALL IS GOOD.YOU NEW ALTERNATOR COULD HAVE A FACTORY DEFECT.IT COULD BE BAD.

Have the whole battery/charging sytem tested. If it has an external voltage regulator or a bad battery, these things can kill a perfectly good alternator.

This is a problem with the alternator. Diode rectifiers and voltage regulator replacement will give this baby a 14.2 voltage output. In this 3L V6 SUV removal of the alternator requires removing the right tire, the right axis and undercovering to reach the 6G alternator. It is a 133mm rectifier with a motorcraft, The serpentine belt is better removed from the bottom. Also keep a bucket on hand to recover the oil from the transmission.

Hi before you go changing the alternator check the alternator belt is tensioned properly if this is slipping it will cause the same thing, Hope this helps

Definately an electrical problem....first off, check the battery and alternator connections to make sure they are tight. The problem has to be before the fuse box because the headlights and interior lights are on different fuses. It sounds to me like a loose wire, corroded battery terminals, or an alternator that is going bad. An alternator is a relatively easy and cheap fix. They cost about $100 and require removing a few wires, 3 bolts, and the serpentine belt.
