Inside the alternator
Charge and load test battery- it may be not able to take a charge and need to be replaced You may a have blown fuseable link preventing alternator from charging battery
You can have the alternator tested free of charge at just about any major auto parts store. By the way, a bad alternator will not "discharge" a battery - the alternator's function is to provide the charge to the battery. If the alternator is faulty, then it is not providing the charge necessary to keep other components from discharging the battery. I had the alternator tested and it was charging. If the alternator has a bad diode, it will discharge the battery. I replaced the alternator and everything is fine.
Voltage regulator or loose wire.
Loose or corroded connections or the battery has a dead cell and will not accept a charge and must be replaced.
The battery light coming on in your Town and Country minivan means that the alternator needs to be replaced. The alternator charges the battery and if it goes bad it will not charge the battery.
Try changing the battery.
You probably have a bad battery. You probably have a bad battery.
The alternator charges the car battery.
Generally, no. If you ran the car after the alternator died (which runs down the battery), you may need to trickle-charge the battery for a half-hour or so to bring it back up to a full charge, but most of the time the battery will not need to be replaced.
A battery charges nothing it accepts a charge from the alternator.
Have the battery checked out. It may have a dead cell and not holding a charge,
Not likely but as alterantor keeps trying to charge a weak battery it may wear out, however as you are not likely to keep a bad battery in the car for so long there should be no damage to alternator if battery is replaced.
sounds like your gauge is broken or there is a short in wiring
Some new alternators will not charge unless the battery has a full charge already.
Charge the battery.
older cars had a generator ,not an alternator, but you can always use a battery charger to charge a battery
Charge it, replace it,test the alternator,Charge it, replace it,test the alternator,
My advice is to charge the battery with a battery charger before starting the engine. You will be putting a heavy load on the alternator if you allow it to charge a dead battery. This could damage the alternator.
I assume you mean how long to charge the battery. You should never let the alternator charge a dead battery if possible. The alternator is designed to keep the battery charged but not to charge a dead battery. You put a strain on the alternator and it can cause a diode to burn out. Drive home and then put a battery charger on the battery to fully charge it.
Well, It could be your battery or alternator or both needs to be replaced but it could just be loose or corroded battery cables
put in new alternator but it will not charge battery. alternator was tested and found to be good. why wont it charge the battery?
That is the purpose of an alternator. The keep the battery charged and to run all the electrics on the vehicle. However it is never a good idea to allow the alternator to charge a dead battery. This will put a strain on the alternator and may damage it.
No, the alternator recharges the battery. Of course the alternator is turned by the engine.
