If the battery is sulfated (or otherwise faulty) to such an extent that it calls for a continuous charge, the alternator never gets a chance to switch off. With the resposibilitiy to run continuously the alternator overheats and eventually fails. Never replace a faulty alternator without also checking the battery.
There is no problem...the problem was the alternator. You have fixed the problem.
If the clock keeps resetting in a 1993 Jeep Grand Cherokee Limited, the problem is probably with the battery. It is quite possible that the battery is going dead after the vehicle is parked, leaving just enough life in it to restart the car. It can also be an alternator problem causing the battery to be drained.
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.
Obviously check the battery. Anyway, if the alternator, battery, and wires connecting them are good the voltage regulator is next on the list.
A quick way to tell if there might be a problem with an alternator is to remove the positive side battery cable from the battery while the vehicle is idling. If the engine dies, odds are there is an alternator problem.
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.
"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.
Could be. But it might be an alternator problem instead of a batery problem. You need a good alternator to keep the bttery recharged. I wouldn't run out and buy a battery without getting the alternator checked.
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.
Possible alternator problem
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.
alternator needs to be replaced. battery also might be a problem due to the alternator not charging it
Your battery is not charging due to a problem with the battery cables or a bad alternator.
Charging system problem. Normally this means there is a problem with the alternator.
i think you are having problem with your alternator its not charging your battery
Your battery is bad, your alternator is bad or you have a wiring problem.
your alternator is not charging your battery..u need to get a new alternator
The simplest method to check where the problem lies, remove the negative cable. If motor still running problem lies with battery.if not running problem lies alternator .
If the light is still on then the problem was not the battery but was instead the alternator which is more than likely defective.
If the battery light is on, it usually means that the alternator has a problem. Have the alternator checked at a local auto parts retailer. If one or more of the diodes are bad, your battery charge will be affected.
The battery light comes on when the alternator is either over or under charging. If the alternator tested good you have a wiring or computer problem. The engine computer is the voltage regulator.
you could pull off your positive battery cable if it stalls out then you alternator is the problem
