Most likely it will not be the alternator. It sounds as though the alternator is working very well. It will be a faulty battery or a battery drain due to something left on or shorted out. Usually a boot light or glovebox light or recently fitted stereo.

Is alternator used once car starts?

The battery "starts" the car...after that the alternator keeps the battery charged. They work together in other words.

Why don't car batteries run out of charges after a few starts?

Because the alternator keeps the battery charged when the car is running.

Why would a car with a new battery not start and once you give the battery a jump it starts it's a 1999 Mercedes c230?

probably has a bad alternator. With the car running use a digital multimeter an you should have 13 + volts (as high as 14.5+) at the battery terminals if the alternator is working. If only 12 volts or so then check the alternator.

Will a bad alternator keep a 1999 S10 pickup truck from starting?

The answer is no . The battery starts you vehicle , the alternator charges the battery so if your alternator is bad your battery is not receiving a charge which will cause a "no start" condition.

4-cylinder 99 tercel starts the stalls starts again and stalls then the battery is dead?

It sounds like your alternator is no longer recharging your battery. You probably need a new alternator.

Will car start if alternator is dead?

Yes, the battery starts the engine, and as long as the battery is fully charged the engine will start. The battery will loose it's charge if the alternator is defective and not replenishing the charge of the battery but the alternator has nothing to do with starting the engine.

If the engine doesn't turn over on a 91 olds cutlass calais how do you know if it is a starter of alternator problem?

AnswerIf the battery's dead it could be the alternator or a bad battery. If not, the starter. Try jumping it. If it starts the starter's OK. Then investigate the alternator and battery.Does it turn over but not start..?? There is a difference. Doesn't turn over would most likely be the battery, which is typically followed by a clicking noise. That would be the starter solenoid trying to engage but the battery doesn't have enough power to do so.If jumping it starts it right up, let it run for 10 or 15 minutes then (while running) check the voltage at the battery terminals. If it's above 14 volts, the alternator is doing it's job and the battery is dead. If the voltage is less than 14, then the alternator needs to be replaced.

Why does myCar battery starts for about 3 days then goes dead?

Alternator is weak and needs replacing. Drive belt on alternator can also be slipping due to being loose. Check the alternator output at the battery with the engine running. It should read from 13.5-16 volts DC. Any less and it needs replacing.

On a 97 cavalier after replacing the alternator and battery the battery light is still on and though it starts and runs fine what is causing the battery light to come on again after start?


Car battery keeps draining and alternator light starts to come on when accelerating?

Check battery cables and alternator wiring for looseness and/or corrosion. Weak alternator--can't keep up with battery load. Check with a voltmeter A fully charged battery should read approx. 12.8 volts withou engine running With engine voltage should increase to approx. 13.8-14.2 volts. If not in this range replace

My '91Mazda 323 dies while driving It starts fine with a boost but dies soon after Help?

Probably need an alternator. Check your battery voltage with a multimeter, without the car running it should be around 12.5 volts with engine off. Start the car & check the battery voltage and if the alternator is charging properly it should be 13.5 or better at the battery. If not check the power terminal at the alternator itself and if only battery voltage (12 or so volts, same as battery) is there then the alternator is not charging.

What causes a 2003 Sunfire engine to keep dying when the battery is not dead?

Have you cheked your alternator? The battery only starts the car and runs electrical components such as your radio and A/C and lights. The alternator is the generator that keeps the engine running once it has been started. Mine was the fuel pump went out

Does a vehicle have an alternator and a starter?

Yes. The alternator is used to keep the battery charged, while using the headlights, radio, a/c, etc. The starter to me is misstated because it actually cranks the engine. The ignition system starts it, and keeps it running.

Your S10 dies intermittantly while running the dashborad lights flicker before it dies but the truck starts after a gap of few minutes new battery could it be the alternator or is it an electric?

Ignition switch is going bad. Will have to replace it. Because eventually the truck will not restart at all.

Check the alternator output with a voltmeter Without engine running and a fully charged battery reading should be about 12.8 volts With engine running reading should be 13.8-14.2 volts May be a bad alternator

Your car wont start just makes a clicking sound?

That could be the alternator or the battery. Try jump starting your car with another car's battery. If it still does not start, it is probably the alternator. If it starts, your battery is dead.

How do you know the problem is the alternator?

If your car doesnt start, it could be the battery. But if the car starts and you unplug the negative cable and the car turns off, its the alternator.

Why some time the terminal voltage of a battery increases more than its rating?

When the alternator starts charging the battery voltage will increase about two volts to charge the battery.

proably yes if not its probably something with your battery or alternator

Why car starts and runs fine then dies when stopping at a light or at all?

Possibly a bad alternator or battery.

What could cause engine to try shutting down while driving and battery going dead overnight if battery and alternator have been replaced?

Sounds like the engine is using the battery as the source of power instead of using the alternator. The main job of the battery is to give power to the starter that "starts" the engine. Once the engine is started the alternator kicks in to maintain power throughout the vehicle, as well as keeping the battery strong. But if the alternator isn't working, the engine will get it's power from the battery. And without the alternator keeping the battery strong, the battery will die. Note: between the alternator and the battery, there is a voltage regulator, this make sure that the battery only gets the power it needs. Oh, one more note, here's a way to tell if the alternator is working properly. (Start the engine, while it is running remove one of the battery cable for just a few seconds.)if the engine stops, then you have an alternator problem still. Check your wires. Or replace the unit. for more answers. email A constant 12 volt drain on the electrical system, even when the car is off

What is the problem when 1998 Chevy makes clicking sound but won't turn over then when battery is charged car still cuts off is it the alternator?

It sounds like the starter is bad. The clicking you hear is the solenoid trying to kick-over the starter. If the vehicle starts but, won't stay running, it could be the alternator, or the wireing to (from) the battery or alternator (most likely the ground wire). Or it could be the dreaded MASS AIRFLOW SENSOR!!!!
