Obviously check the battery. Anyway, if the alternator, battery, and wires connecting them are good the voltage regulator is next on the list.

My 93 Mercedes Benz the light of the battery came on when i was driving. I change the battery recent and the altornator so what could it be.?
Battery light usually means alternator not charging. Most common solutions would be be a bad alternator, bad connection, or loose alternator belt. If the battery and alt test ok than check the connections to the alternator and battery.
Is charging of car battery chemical change?
Yes. The charging causes a chemical change in the electrolyte of the battery.
Opel corsa battery problems?
Check that alternator is charging battery properly and change battery to see if you still getting same issues. It can also be a leak in your car radio, burnt alternator diode, or a shorted coil in the central locking system or windows.

Why is your battery light on and Battery meter pegged high on the instrument panel in your 2002 F150 pickup Alternator If so how do you change it out?
I had this problem. The alternator was fine, it was the battery that was bad. The alternator was "pegging" out the indicator bc it was trying to charge the battery, but it wasnt taking charge. Take the battery out and have it checked.
Car battery wont hold a charge?
You might have a bad battery or your alternator is not charging the battery.Easy way to do is to take your battery to the auto part store ( Auto zone, Pepboy..) and let them test it for you.If it bad just change it.If it's not then your alternator might be bad.
What must be done when a 1992 Lexus sc300 wont keep charge after altinator change What is the problem?
Bad battery? Could be the wiring harness in the charging system. If the replacement alternator was a used part, it might also be bad (yes this has happened to me).
If the car is running and from time to time it shows charging system?
could be a loose alternator belt or the alternator brushes are very worn if so best to change the alternator also if the signal wire earths somewhere the battery/alt light will come on
Why Battery light flashes on and off?
I just had this happen on my F250. The manual says problem with the electical charging system. I went ahead and drove it until the power production completely failed. I am going to change my alternator but it could possible be the voltage regulator.
You have a 1991 ford explorer my battery idiot light just came on and the amps gauge is showing 10 amps the car starts and ruNsbut the ac doesnt work is this related what do you do?
the ac could be related and if the battery light is on it means that your alternator is not charging properly which in turn could stop your ac from working due to lack of power I would change my alternator and see if that fixes your problem.
What does a battery temperature sensor for a Plymouth neon do?
The battery temperature sensor is used to fine tune alternator output for better fuel economy and longer battery life. Note, this change is alternator output is very minimal and typically cannot be detected using a Digital Volt Ohm Meter (DVOM). However, if the charging system is hooked to a lab scope, a change in alternator output will be detected. This change is typically seen in amperage output, not voltage.
How can you test your alternator if your battery is dead?
A lot of auto part stores will test them for free. Give them a call. Your alternator can only be tested when the engine is running, therefore you will have to get a boost or use a battery charger for the battery. If you have a voltmeter, test at the battery terminals with engine still running, if you get 13.5 to 14.7 volts, the alternator is charging. In some cars, the voltage could go over 15 volts if the battery is close to dead (right after being boosted), but the voltage should go back to normal as the battery gets closer to fully charged. Turn off the engine, the voltage will go down to 12.5 volts if the battery is now charged, lower if is not. If there is no change, the alternator is not charging. KGP484
