It could mean the alt is nearing the end or a loose connection of the alt wiring. TAkeit to auto zone and have the alt. checked
That is the charging system warning light. If it stays on or flickers it means the alternator is not outputting enough voltage to keep the battery charged. With a digital volt meter you should read from 13.5 to 15.5 volts at the battery with the engine running. If not the alternator or the voltage regulator is defective. The voltage regulator is more than likely built into the alternator.
If the battery light flickers, it's losing voltage. It would be worse when the lights and other accessories are running. It just may not be enough to kill it yet. I would suspect parts in this order. Alternator(if there is a voltage guage, should be around 13-14 volts) discharged battery

what causes the battery light to on a 2005 ford expedition to come on?
Depends on what the bulb is rated for. If the voltage of the battery matches the voltage of the bulb it will light up.
Your battery is not being charged because of a problem with the charging system Whether its a problem with the alternator / voltage regulator , the serpentine belt etc . you should have the charging system checked
it takes 1 C type battery <><><> That answer is not really very helpful because the question doesn't say what the voltage of the light bulbs is! This question cannot be answered without knowing at least the voltage of the light bulbs and also the voltage of the battery that is being asked about.
The battery isn't being charged
The brightness of the light will change with the voltage of the battery.That's not always related to its physical size.The higher the voltage is, the brighter the light will be, until you reach oneparticular voltage where the light goes out, because you have burned it outwith overvoltage.
Sounds like battery/alternator problems. Check battery first, it's cheaper to replace.
If it is undercharging the battery yes, but if it is overcharging the battery no in most instances. If it fails completely the light will come on.
The battery light comes on when the alternator output voltage is too low or too high. You have a wiring or regulator problem.The battery light comes on when the alternator output voltage is too low or too high. You have a wiring or regulator problem.
It is possible you have a bad alternator, or a bad connection at the battery. You can take the car by your local auto parts store and have the altornator checked.
Probably the battery is discharged. It's possible the battery is not charging because the power adapter is dead. Check the power adapter with a voltmeter.
Need more information. Wattage of bulb, voltage of bulb, voltage of battery and wire size of the circuit.
Does alt. light stay on after car is shut off? If so could be voltage regulator is defective and overcharging battery when running Does light stay on after car is shut off? If so could be a bad voltage regulator--if so may be overcharging battery Check voltage readings at battery should be around 14.2 with car running -- if much higher than this voltage regulator is bad.
Check battery connections, check alternator out put. Exc.
Your battery has low voltage and needs recharged, check for loose battery cables, if the light stays on have your alternator checked.
Take it to auto zone and they will check out the alternator for free.
If you have 2004 Chevrolet trail blazer and your battery light indicator is on, it is probably because of voltage across the battery is 12.1v.
When the battery light stays on or flickers. If you have a voltmeter, you can check voltage at the battery. With car off, should read 12 volts. Running, it should be 13 or 14 volts, unless there's a problem with wiring between the alternator and battery. You can check voltage between big wire, usually red, from back of alternator and frame while running, but watch out for belt, alternator fan blades, other moving parts.
Yes as long as the battery and bulb are rated at the same voltage. (Boy Scouts do it every day with flashlights.)
When the ignition is turned on, battery voltage passes down the wire to the alternator to 'excite' the alternator when the engine starts. When the engine starts and the alternator generates a voltage, the light is extinguised by the charging voltage cancelling out the battery voltage coming down the wire. If and when the alternator completetly fails the the light will come back on as there is no sancelling voltage. if the alternator produces a voltage lower than the voltage from the ignition switch then the battery light will glow.
The ABS light is most likely on because of low voltage, same reason for the battery light to be on. Get your alternator tested.
