Why does the battery light come on while driving even though the alternator is charging the battery?

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.

Why does your battery warning light stay on despite the battery being charged normally?
Sometimes even though the voltage at charging is good the battery or alternator could be low on charge or charging low for your vehicles specs.
Why would the battery light on a Clio 1.2l always flash even though when it was serviced there was nothing wrong with it?
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.
What could be causing the the battery light to stay on after replacing the battery in a 1993 dodge caravan?
The battery light indicates that the battery is not receiving a charging current. You may have a bad alternator or a broken drive belt (if you have a broken belt you'll have overheating and power steering problems too, though).
Can a faulty alternator drain a new battery?
It can, though it is unlikely -- the alternator and the voltage regulator would both have to be faulty. A faulty alternator will not charge a battery, though, so it may seem normal until the charge put into the battery at the store runs out.
How do you reset the battery light on a 1995 Toyota corolla?
The battery light isn't a light like the check engine light...well, it kinda is. It doesn't represent a code though. It's saying that there is something wrong with the charging system, like an alternator or battery going bad. Good Luck!!
Would a bad alternator make a car overheat?
No, not an alternator itself. A slipping belt driving the alternator and the water pump could though.
What wiring could keep the alternator from charging the battery?
I had this problem in the past, and only later found that the battery ground wasn't good. Removed black battery cable from the grounding point (opposite end of cable from battery), cleaned the spot where it was attached, and cleaned the cable end, then reattached it. Worked fine then. Only one possibility though.
Why would a 1995 ford probe not stay charged once you have changed battery and alternator?
If the battery continues to go down even though the system is charging it normally indicates there is an amperage draw. to test it without any meters; disconnect the negative battery cable and observe when you touch the connector to the battery. If there is even the slightest spark, you have an amperage draw and that will run your battery down.
Why does the battery light keep coming on your 1995 Pontiac sunfire even though the battery is new?
It could be your alternator is going bad
Will a car engine start with a new battery even though the alternator is bad?
Most definitely.
What is the purpose of a diode in a car connected after the battery?
I think the purpose is so that the battery doesn't drain itself trying to turn the alternator as though it was an electric motor. The diode only lets current flow in one direction, from the alternator to the battery.
Can someone tell me why the battery keeps dying even though i have replaced the alternator?
Is it new? if it is it's not the battery. If it's really old your battery most likely is leaking.
