Battery Light staying on

If the dashboard mileage light on your 2001 Buick Regal LS is very dim and the Service Vehicle Soon (SVS) light and antilock light stay on, there could be a few potential causes for this issue. Here are some things you can check:

1. Dim dashboard light: If the dashboard mileage light is very dim, it could be due to a burnt-out bulb or a problem with the dimmer switch. Try turning up the brightness using the dimmer switch, and if that doesn't work, check the bulb and replace it if necessary.
2. SVS light and antilock light: The SVS light and antilock light staying on could indicate a problem with the car's computer system or with the antilock brake system. It could be caused by a faulty sensor, a wiring issue, or a problem with the computer itself. It's recommended to have the car's computer system scanned for error codes to determine the root cause of the issue.
3. Battery or charging system: A weak battery or faulty alternator can cause electrical issues in the car, which could be related to the dim dashboard light and the warning lights staying on. Have the battery and charging system checked to rule out this possibility.

Assume you mean drains of power not fluid. Does battery light show on dash with engine running. Make sure that the alternator drive belt is correctly tensioned (longest side betwen pullys move 1/2" up/down). If it takes a few days to loose charge temp fix is to use a solar battery charger that can charge battery when car is parked. Hope this helps.

Sounds like you might have wire problem.
Try turning the key to the point before ignition. This is actually a dashboard test that have all lights on the dashboard turn on. Try to see if the lights are completely bright or a bit dull in the light.

You battery might be uncharging itself, instead of charging. I have tried that. even with an only 1-2 day old battery.

There is obviously have a drain on the battery. You have a faulty break light pedal switch causing the lights to stay on, or your turn signal switch is bad. your brake lights run through, the turn signal switch too. That could also cause the problem.

check if the alternator is charging

yes it could.If the alternator is bad your battery light should come on while running.when u replaced the battery it should have ran good for a minute till the alternator started draining draining your battery.Then the battery light would come on.I would replace it or have it checked.You can check it by starting it up and keep any elelectric off radio,lights,ect.then disconnect the battery if the car stalls its the alternator.the car would stay running with good alternator

this symptom is asociated with the lights relay or the light switch.

THE CHARGING SYSTEM TURNS ON THE BATTERY LIGHT. HAVE THE ALTERNATOR TESTED ALONG WITH THE BATTERY.

its not charging, check the belt that drives your alternator, your fuses, check for some loose connections at the back of alternator, if the light stays on while the engine is running, replace your alternator. good luck!

Does the car run fine and start fine if you don't turn the head lights on ? The symptoms you describe here suggest a battery that is run down, in need of charging or a faulty battery, however if the same batter starts the car without a problem then you have a much more tricky problem to sort out as it seems your lighting circuit is then producing a direct short on power circuit resulting in nothing working. Do the headlights actually come on when you do this and stay on while every thing else goes off ?
