A light in your car might be on, running down the battery!!
If your engine is running , and the battery light comes on , that indicates that your battery is not being charged
its the alternator if the car is running with a battery light on. but check fuses first
MAYBE IT COULD BE A BAD SENSOR. IF IT IS RUNNING GOOD I WOULD JUST IGNORE IT.
The battery will drive a current though the lamp, which will eventually drain the battery.
battery light on 2000 f250 will blink if battery is not properly charged. an example is if you have been sitting all day with stereo olaying and engine not running, you have run battery down some. after starting engine and driving, the battery light will blink while alternator charges until battery is fully charged i have only experienced this at night when lights are on creating extra load for alternator ,after running battery down with stereo all day
That your engine is not running.
That light doesn't mean that your battery needs to be replaced. It means that your battery is not being charged while the car is running. Have your alternator tested.
That would be short for "generator" light. If that light is on while the engine is running, the charging system is not working and you are running off of battery power only.
If your 1997 Mercury Tracer has a battery light that blinks on and off while the car is running, it most likely means that the battery is not charging. This could be an issue with your alternator.
u might of left the frickin light on
That it needs to be charged or is running out of battery.
you need a new alternator/belt
on my old 1.2 clio the battery light came on as there was fault with the alternator and it needed replacing. As far as i know the battery light comes on when the battery is not charging or there is a fault with the battery.
Dead cell in the battery requiring a replacement battery or something is on pulling power from the battery. Can be any light on the car or any relay.
It has one on the panel. The first indicator.
The battery light indicates the system is not charging. Have the charging system checked. If the alternator is not charging, the engine will quit running and leave you stranded.
Most likely it will not be the alternator. It sounds as though the alternator is working very well. It will be a faulty battery or a battery drain due to something left on or shorted out. Usually a boot light or glovebox light or recently fitted stereo.
Alternator bad or wiring fault to alternator.
A red light means your DS is running low on battery, and needs recharging.
Check your alternator, Mine did the exact thing. The Battery light and the !!BRAKE!! Light came on and couldn'y figure it out for the hell of me, did volt tests while running and only had 12.5 volts on the battery. I changed the alternator ($179.99) and got back to the normal 14 or so volts while running and lights shut off. no idea why the brake light was on at all.
If the battery is running down overnight then 2 things are happening. Either the battery has what is know as a dead cell and must be replaced, or something is on drawing power from the battery. Dome light, under hood light, trunk light, under hood light, glove box light, or a relay may be stuck.
You left the light or something on last night and ran out the battery or your battery died
Dead cell in battery, some light is on and is drawing power when the car is not running, or a relay is stuck. This is assuming the alternator is good.
The alternator may not be charging it enough. With the engine running at an idle check the voltage at the battery with a DC digital voltmeter. It should read from 13.5 to 15.5 Volts. Anymore, or any less, and the alternator is suspect. You might also have a defective battery.
