The numbers you referenced seem as though they may be specific to an individual tester, unless you're talking about 13.40 volts vs 12.70 volts. If the alternator is only producing 12.70 volts, you'll probably run the battery down. How did you come up with those numbers?

What is wrong 97 Mystique 2.0 has spark and fuel into cylinders turns over but won't start?

it might be the alternator, try and get it tested. if the car won't start the battery will also be dead, you could replace the battery and drive it to get the alternator tested at an autozone or advance auto parts for free.


How long must you drive a Mercedes CLK 320 after replacing battery?

If the battery was charged when you installed it, you do not have to drive the car at all. If not you should charge the battery and not use the cars alternator to charge it.


Why does the battery not charge?

Corroded or loose battery connections, loose alternator drive belt, defective alternator, or dead cell in the battery.


Could the problem be your alternator or the battery when the check gauge engine light comes on while the battery gauge keeps moving.?

that depends on what your voltage gages says while the car is running. while the alternator is spinning, it should generate 13 to 18 volts. if that's the case, your alternator is fine. If not, you need to replace it. it won't charge the battery, giving you about 20 minutes of drive time, but the more you drive the battery like that, the more you will stress it out. if you stress the battery too much, it may go bad on you too. you can get the battery and alternator tested at most auto parts stores. many stores will even test your parts for free.


How long do you run your car after a a car jump?

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.


Will a dead alternator drain a battery?

Yes. If the alternator is dead and you drive the vehicle, all the power is coming from the battery and it will eventually drain completely. Also, if a diode is shorted inside the alternator, that can drain a battery.


How long do you have to drive around to charge a car battery after jump starting a car?

You should never drive a car around for long after jump starting a dead battery. This puts an enormous strain on the alternator. Alternators are designed to keep a good battery charged, not to charge a dead battery. You can easily burn out a diode in the alternator. Jump start the engine and drive it somewhere and connect a battery charger to the battery and charge it fully.


What causes alternator battery light to come on and then off itermittently?

Can be loose or corroded battery connections, loose drive belt, or the alternator is failing.


Why is your new alternator not charging your battery?

The drive belt is not tensioned. The fuse in the line between the battery and alternator is blown. The battery has a bad cell. The voltage to the alternator field is missing from the regulator or ignition switch circuit.


Why do you think a 1998 Chrysler Sebring makes a flutter noise when you try to start it do you think its the battery or the alternator?

Could be starter drive or weak battery you should check out the battery first


How do you tell alternator is bad?

The best way is to drive it to your nearest auto parts store and have it tested. You can test it somewhat yourself. Start the engine and use a volt meter to test the voltage that is being supplied by the alternator for the battery. If it is less than 13.5 volts the alternator is bad.


Why does your battery keep draining on your 2000 Chevy Monte Carlo?

Defective alternator, loose alternator drive belt, dead cell in battery, or something is on pulling power from the battery.


Can the alternator kill the battery?

Yes.Normally, the alternator charges the battery as you drive, and if if doesn't work, the battery never gets charged causing the battery to discharge. A discharged battery will have a short life, and is more likely to freeze in cold weather which ruins the battery completely. Note that an alternator should always be tested hot (within 5 minutes after driving for at least 45 minutes) . A bad alternator with a bad voltage regulator or rectifier diode may test good when cold.In some cases, an alternator may be "bad" because a rectifier diode (internal part like a check valve for electricity) no longer functions. With a bad diode, the alternator can, from time to time, actively discharge the battery when you shut the car off depending on the (effectively random) position at which it stops.


Why won't your battery stay charged?

Defective alternator, dead cell in battery, something on pulling power from the battery when the vehicle is idle, corroded battery cable connections, or loose alternator drive belt.


Why would a 1999 crown Victoria PI battery light flicker on and off while driving?

Double check and tighten all the connections on the alternator. Check and clean both battery post connections. Check and clean the fusebox connection under the hood (right behind the battery). Test drive your car. If the above didn't solve the problem, have your alternator tested (especially Capacity test and the Diode test!). While you are there, have the battery tested. Hope this helps!

Why Mazda Protege won't charge battery?

One of two things is normally wrong. Either the battery has a dead cell and will not accept a charge, or the alternator is defective. With the engine running at idle check the voltage at the battery with a digital voltmeter set to the 20 Volt DC scale. If the alternator is good you should read from 13.5 to 15.5 Volts. If the alternator has a separate drive belt then it is possible the drive belt is broken.


How can you tell if its your battery or alternator?

With the engine running check the voltage at the battery with a DC volt meter. It should read from 13.5 to 15.5 volts if the alternator is good. Or, you can drive it to your nearest auto parts store where most will check the charging system for free.


Just replaced alternator on your Mazda tribute and the battery light is coming on slightly what would cause this?

Loose alternator drive belt or loose or corroded battery cables. The battery itself may also be bad.


A little puff of smoke from the alternator but the battery light is?

You have an electrical fault in the alternator. Don't drive the car, get this fixed, or you risk a fire.


What is wrong when battery light comes on?

Normally the alternator is defective. It can also be a loose alternator drive belt, or defective voltage regulator.


Battery KEEPS draining?

Need more info... How old is it? Do you drive short distances? Does it sit around not driven a lot? Check for a short, bad alternator, or fried battery. If you take the car to an alternator shop, they can usually tell you for free if it's the battery or the alternator.


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.


Can you drive if my battery light stays on?

yes but you shouldn't if alternator is not charging battery is bound to go dead and you will get stranded somewhere.


What does it mean when the battery light comes on in your car while you are driving?

Could be that the alternator is not charging the battery properly Check with a voltmeter A fully charged battery should read around 12.8 without engine running With engine running voltage should read around 13.8-14.2 The most likely cause is a broken alternator drive belt


What are the symptoms that your car might need a new alternator?

Battery not being kept charged. Drive the car to most Auto Parts stores. They will check the alternator for free. Or, if you have a multimeter, check the voltage at the battery terminals with the engine running. Should be from 13.5-15 volts.
