Question about 1998 Buick LeSabre

1 Answer

98 LeSabre having issues with battery drain while driving. Shop cannot find anything else wrong after checking on their machines. They think I am crazy and think it is just the battery gauge now. I

Just replaced the alternator as well as the battery. It will die out as I am driving. Also seems like there is a noticeable click right before it goes. Shop also checked all the groundings, wirings, etc. and nothing is popping out at them. I cannot accept that it is just a faulty battery gauge when I SEE everything dim or even die out completely as I am freaking driving! PLEASE HELP!!

What shop did you take it to ? The charging system on your vehicle is computer controlled and so is the volts indicator gauge. Have you tried the buick dealer ?

SOURCE: car dies while driving

Sorry to hear about your vehicle. First things first. When you say driving, what are you ding and where are you? such as; on the highway, at a stop light, making a left hand turn, coming to a stop. Second, when you say dies , do you mean your driving, your cars "shuts off" and your stuck in the middle of the road? and when you say stays dead do you try to start it? does your radio come on? are your light on or are they dim? all these are very helpful in diagnosing the root cause of this concern. also was there any work done recently to the vehicle? if the car is running and it dies a few things could be the cause. one, not that common, your engine could be starving of fuel, fuel pumps, filters and injectors and throttle body could all cause a fuel starvation. two spark cuts out. I work for volvo and i see coils (devices that increase spark) on 98+ vehicles literally crack in certain areas and cause rough idles, choppy acceleration (stuttering while getting on a freeway) but third and most likely battery/ charging system (these are just three common flaws there are lots of other little things associated with the electronic fuel injection system and monitoring that could and may well be the cause). the way your vehicle works is the battery stores a charge and your vehicle draws from the charge what it needs. on start up its battery power until your alternator reaches a certain speed (or the computer tells it to turn on) that supplies the power to the vehicles electrical system. now that i know you have an understanding i can suggest what, giving the limited info i have, i would look for first. if there is no rough idle apparent when the vehicle is warm that suggests fuel probably is ok and so is spark. now if your alternator cannot keep filling the battery up with an electrical charge, your car could just plain turn off. now this could cause a slow cranking when trying to start the car again and it may not even start. but as to why it will come back to life after a few mins or few days is interesting. check connections at the battery because that will prevent the flow of electricity. make sure its clean of dirt and paint too. take a wire brush and clean it. also is there anything white or powder-like on the terminals? oxidation causes a poor connection. that can be cleaned with spray cleanser from auto parts stores or scrubbing with baking soda and water but thats my guess without having the car to test. please post what you find out about your car.

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.

do you get fuel pump pressure, should be about 40 psi what about compression and spark on a saturn would be stronger due to many reasons one of which being different voltage of coils

Car died while driving!can only jump start.dim lights ect


If all your connections are clean and sound, then your car should be able to run without a battery. Start the car and disconnect the negative terminal. If it stops your alternator is faulty. This would explain dim lights that are draining the life out of the battery instead of being alternator driven. Same as the dieing while driving, the battery can't keep supplying power forever without being recharged by the alternator.

If the alternator is ok, the battery needs replacing. Repeated draining of batteries kills them.

Why did my car seem like it wanted to stall and die when i changed the battery? is it my alternator?


That sounds like a bad connection somewhere, battery, particularly the earth strap, alternator, fuse box main connectors. Something like that. You can test the alternator output with a volt meter.

Sounds like your alternator to me. The alternator is not charging the battery so when you drive it, the battery is being drained. It can die even while you're driving. I would get the alternator checked and get a new one if necessary

91 Saab 900 keeps dying *****cont'd*******


If things are clicking, flashing, flickering and dimming at random then you have a short or a grounding issue. Also, if your battery isn't keeping a charge you should have it tested. If it were my vehicle and I just spent $800 on an alternator and labor I would want to see 14amps coming from my battery and alt. combined.

You need an alternator! The problem is in the alternator and more specifically, the regulator. It seems to be just hanging on and it is possible the mechanics didn't bother to test for proper charging amperage and voltage. The reason it would dim is because it was relying heavily on the battery instead of the charging system provide the adequate power.

My 2001 audi seems to start up fine and but after


have your alternator tested it sounds like your battery is pushing out out the power to your engine which causes the battery to drain. if you can start the car again pull the negative battery cable if the car dies after you remove the cable then your alternator is shot.

Elictrical system flashes on/off, then dies.


when you were driving, after replacing the battery, if u felt the car loosing some horse power, until it dies, then YES its your alternator, it is not recharjing the battery with power, so the car keep on sucking the battery until it dies, try to check your alternator, or check your the plug "located on the alternator itself"
