Check to see what the voltage is at on on the large wire on the back side of the alternator. If its more than 14volts (with the car running) than put one test lead on that wire on the back of the alternator and the other test lead on the POSITIVE terminal of the battery. you should see less than .5 volts. If you see 12 volts or more than the wire from the alternator to the battery is open or has a lot of corrosion somewhere.

SOURCE: New battery & new alternator, still not charging...

Take it to another auto parts store to test to verify.
If you put a voltmeter on the battery when the T+C was running, it should read 14-15V.
It could have a bad diode. If this is the case the alt. will be pumping out AC instead of DC. This is BAD. Batteries do not like this and the battery will fail because of it.
Be careful in those 'auto parts stores'. I have found that they employ alot of 'kids' who know little about how a car works. Try NAPA. They are much more knowledgeable and professional. But they cost alittle more.

SOURCE: Can not get battery light to go off on 2002 pt

My name is Ron,I will try and help you.Was this battery on the vehicle when the original alternator was on the vehicle?If so It is possible that the alternator was the begining of all the problems.The alternator produces ac voltage,12 volts ac,like house current.This is called alternating current,back and forth as you may.Before the ac voltage can leave the alternator,it is converted into dc voltage(directional current).This dc current only moves in one direction,thats why there is a positive and a negative.Diodes cause the ac voltage to only go in one direction( dc volts) there for creating dc volts,12 volts.These diodes are made to allow current to pass threw them only one way,current can not go backwards threw these diodes,unless they burnout,then they will allow voltage to leak out ,going backwards,creating ac voltage,therfore charging your battery up and having a battery with some ac voltage,or a lot of ac voltage.If this has happenned any motors ,such as starter motors will not turn to start a vehicle,cause they do not know witch way to turn.The battery will not be salvagable.Get the battery checked ,and ask them to check it for ac voltage,They might think your crazy but it happens,more than you think,a lot of mechanics dont know this,so you may have to ask more than 3 or 4,before you get a mechanic to understand .this is just a suggestion to try.Ac voltage will cause the battery light to light up.also check battery connections at battery and alternator for looseness and black corrosion,battery terminals most likely will have this.The large post on the alternator is the out put wire to the battery,Add another battery wire or small cable to the back of the alternator to the battery and see if this does the trick.May be this will fix ya,,,,,for more help

SOURCE: I have alternator charging battery problems.

hello there:
you're problem may be in the alternator or the battery to find out you will need a volt meter and have the vehicle running to test the alternator set you volt meter to dc voltage and touch the positive side with the red lead and the negative side with the black lead you should show 14 to 14.5 volts if not replace the alternator then with car off using the volt meter and test the battery the same way you should get 12 to 13 volts then wit the volt meter still hooked up to the battery with the help from someone try to start the car and see if the voltage drops below 10 volts if so the battery might be shot....hope this is helpful best regards D.Jones p.s please leave a review thanks

Battery light keeps coming on even though the battery is fully charged in my 97 ford falcon wagon

Hi Tracey I'm just trying to make sure your battery has not gone dead at all and the battery/charging light stays on right if this is the case there are two plugs on top of your altenator the smaller one is the connection for the battery light it maybe loose and not making contact which it will make the light stay on try to wedge a rolled up match book cover in with the plug and see if it go's out if so try to get a dude with brains to fix the inside metal connector to fit tighter on the pin don't use dielectric grease it's not conductive and will make it worse get the plug to fit tight and if you have to leave the match book cover or whatever you used to keep it that way

My battery light keeps coming on even though my mechanic said there's nothing wrong with it.

If you're certain the battery is fully charged, then you need to check your serpentine belt out for bad teeth which will cause it to slip, then your alternator with a multimeter to see if it's charging the battery.

A simple method to see if the alternator is working at all is to start the car, then remove the negative battery terminal. If the car dies immediately, the alternator isn't charging.

This should help you isolate your problem.

2003 bmw x5 4.4 battery light stays on

Brother Mark, changing the battery with a new one being done won't make the light go out, as you noticed. Light is still on so you changed the alternator. Good, but the battery light is STILL on. This only means that the charging circuit from the alternator is not working in the voltage regulator or the wiring is not connected properly to the alternator/regulator. A new battery will show over 13 to 13.5 volts not connected. An old battery will still show 12 volts and still be weak or bad. After connected and engine running, the system will show at least 14 volts because alternator/regulator is working properly, using a voltmeter/load tester connected to the battery. If after replacing the battery and alternator it is still reading 12 to 13.5 volts, it is not working and the light will stay lit on the dash. You may have purchased a faulty alternator if the system tests out this way. Have your system checked with a volt meter or load tester bit be sure all the connections are proper and clean.

Battery light on and off

The battery light means the alternator is not charging the battery. The charging system would need to be checked out when the light is on.

My Sansa fuse will not start, or charge

This sounds like a bad alternator.Remove the battery and have it charged and tested, if the battery is fully charged then truck should start and run for a while.With a bad alternator the battery light will come on and truck will run until battery life is discharged.With the battery fully charged and truck running put a tester on the battery to test the alternator output. the reading should be 13.5 - 14.7volts. any reading below 13.0 replace the alternator.
Do not drive truck to far as when the battery voltage gets low truck will die out.

Check battery light stays on even though the voltage at the battery is 12.90 with engine off and 14.60 at idle ?

Your alternator is putting out good voltage, so internal voltage regulator is working, but what's happening the Diode is what going bad, the alternator put's out ac voltage, and the Diode turn it to dc voltage, could mess up your battery and elec. system, the Diode are like a one way valve, have it checked with a alternator, battery, starter tester, most auto parts will do this for free, if Diode's are bad it will show up in there tester.

My battery wont keep its charge or charge properly ive tested the

Go to an auto parts store and buy a load tester for the battery. It doesn't cost much and sometimes if you bring the battery there they will test it for you with a load tester. It may have a dead cell which won't allow it to hold a charge or put out enough power. If you need a battery, some shops will install them for free. Good luck.

Battery keeps dying, it's alternator was replaced in August and a new battery, so why is there a problem now ?

You may have another Alternator issue so get the charge rate checked. Then, look for a leakage issue like the glove box lamp staying on, or the lamp in the trunk or boot staying on. I have even seen the lamps in the footwells stay on and drain a battery overnight.
An easy test is to use a test lamp. Make sure all the doors are closed and everything is turned off (tail lamps etc). Disconnect the battery negative and connect the test lamp between the battery post and the cable clamp. If the lamp lights and stays lit, you have a leakage. Begin by disconnecting the courtesy lamps or removing the bulbs. When the test lamp goes out, theres ya leakage. If you have a charging system connected to the vehicle which charges a second battery, like one in a caravan, check those circuits too.. And even though the Alternator is new, it may still be the cause of the problem.. So check it out as well..

1997 ford taurus GL battery light stays on or sometimes dim alt. checks o.k. what is the problem.

When you say it check ok, can you please explain what you mean in more detail, because if your Alternator light comes on or is dim, your alternator is likely not producing enough amps to fully charge the battery. The battery may test good, but the alternator has to work too hard to keep it charged. Have a check run on the amperage output on your alternator to see if it produces the factory recommended amperage. You can get a tester or probably borrow one from Auto Zone auto parts if there is one near you. If not, you can buy an amp tested from your local auto parts store or you can take it to your local shop and they might test it for free.

1983 ford bronco 302 engine wont stay running after jumped

keep in mind, your engine use both source of power to run, one from the battery and one form alternator. If the alternator is good, your engine should stay running regardless if the battery is good or bad, the alternator should keep the engine running. It sound like to me the alternator is faulty not charging your battery or keeping your engine running, even though the alternator is brand new does not mean is good. My guess I would take the alternator back and get another one. the reason why your car ran for 25 min and die it has no source of power to keep the sparks going although the alternator should keep the engine running and at the same time charging the battery but is not.
