There is no problem...the problem was the alternator. You have fixed the problem.
Your battery is not charging due to a problem with the battery cables or a bad alternator.
Obviously check the battery. Anyway, if the alternator, battery, and wires connecting them are good the voltage regulator is next on the list.
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.
If the alternator is good and the battery does not charge, then the battery may be bad. There could be problem with the electronics. You will need to take it to a place where they sell batteries. They have equipment to check out the battery and the wiring.
have an alternator, battery, and electrical check to find out what the problem is. battery may not be taking a charge, or the alternator is not putting out enough voltage.
"Big" Battery Damage Alternator?No, it should not damage the alternator. If this has happened it's probable that the problem is somewhere in the wiring circuit connected to the battery and alternator.
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.
If the light is still on then the problem was not the battery but was instead the alternator which is more than likely defective.
your alternator is not charging your battery..u need to get a new alternator
Your alternator is probably rebuilt and not really new. I have had this problem several times and I have bought a new battery and alternator. The alternator keeps your battery charged and powers your electrical system, so even when driving you can lose all power in the car from the alternator draining your battery. Take the battery and alternator to an auto store and they will test both for free. Ask them about the difference in a rebuilt alternator and a brand new one. This is a very common problem.
Your battery is bad, your alternator is bad or you have a wiring problem.
