Sounds like a bad connection. The alternator only charges the battery, so if it or the voltage regulator in the alternator fails, the battery would slowly run down, not die all at once.

SOURCE: Low voltage, the battery runs low when running the car

What is the voltage you are reading? Is it below 13.2 or so? Also have you checked the current with the engine off to see if something else is working that should not be on. I ran across this twice while working on a truck and car. A relay that was wore out keep trying to close and would drain the battery every couple of months. Sometimes you can hear them clicking or buzzing. Touching them sometimes they are warm or real hot. But that is not a sure sign it is bad. In my Trailblaze they get hot but are ok. Another thougth is the belt on your alt, correctly set to spin it at the right voltage. I have ran across this many times lately with serpatine belts.

SOURCE: My 97 buick lesabre starts m runs fine once it

check your fuel pressure sensor, that is located on your fuel rail. it would have a vacum hose to the top of it. cause it would cause it to give it plenty of gas upon start up (like a choke) but fails to stop feeding it so much fuel once it warms all the way up. just a suggestion.

94 buick 3.8 engine not charging Battery right


Its a fairly simple system. The alternator gets a signal from the circuit for the warning light and-or gauge to activate the voltage regulator inside the alternator. The large wire between the alternator and the battery or starter is fused for protection.
Could be a problem with that circuit back to the instrument cluster, or the circuit to the battery, or a ground connection. You could also have a second defective alternator.

94 nissan pathfinder voltage to battery issue


run the fault codes and check for injector problems
batteries have no set life ( that is what the warranty is for--- new batteries regularly fail at the end of the assembly line ) so if could be failing
have a load test on the battery
Have an accredited auto electrician check the output of the alternator to check it and the voltage regulator
low battery voltage will upset the ECM program

2000 Buick LeSabre died at 70mph, volt light came on when engine went, I coasted to a stop and then tried to restart, the starter spun but the engine wouldn't catch to start. Electronics were all still...


Think my friend sounds like your alternator has gone bad on you... Your battery still holds power and enough to run your electronics and starter but not enough power to run your ignition components.
