SOURCE: 2002 sonata 2.4l battery dash light on. replaced alternator. Still not charging

I don't know if your car has an integrated regulator or not; some house the regulator in a section of the alternator case, others mount it remote from it. The regulator monitors the load and battery voltag,e primitively but effectively, and controls the current flowing through the field winding of the alternator to ground, changing the magnetic field intensity and consequently the voltage output of the alternator. The 'hot' end of the field is internally connected to the + output, the 'cold' end is controlled by a transistor inside the regulator which, in turn, is controlled by circuitry monitoring the system voltage.     Some alternators can be tested by sticking a wire through a specified opening, actually shorting the controlled end of the field to ground briefly, while monitoring the voltage across the battery, doing this though for seconds only. This essentially bypasses a suspected defective regulator; this causes the output voltage to rise instantly to its maximum of ~17 volts if the alternator is OK.
I don't recommend poking a wire at random into an available opening so having a service manual (Haynes-Chilton) would be nearly mandatory.

SOURCE: Charging Light On After Replacing Alternator/Battery1999Windstar

Hi, I can't tell you exactly what is wrong because there is too much involved at this point, what with 2 shops working with it, but I can give you some advise on what else to check. On the alternators and the wiring that supports them a small volt charge is taken off one of the slip rings, where the brushes ride, for the purpose of turning out the light. As I remember, this is a yellow wire that runs back to the dash.

To the alternator, it would be one of the wires that plug into the side of the alternator case.

First check alt At The Back of Alt Big Red Wire Were hooks to Post (stud) Do you have voltage ?? How Much??
What Voltage do you have at same Place with Engine Running ??
Now At wires Were they plug into Alt ,Top. Wires in White Plastic Clip, Do You Have Powe With Key On ?? How Much Voltage??
Jump across the 2 in the clip (with Engine Running)ONLY TEMPORARY!! Do You Have Voltage at Battery ?? How Much??
If Over 13volts With Clip On (Jumped) You Need A Internal Voltage Regulator ..
Is Batt Light On on Dash ??? Theres A Lot Of Testing You Can Do !!! And I will Need More Infomation to Keep Going ... These are just some Possible Problems No Way In Depth ...
Could Be a Number of things Or May be Just as Simple As a Blown Fuse, Dirty Batt Cables ETC etc etc I Hope It Puts You On The Right track !!!!!!!!!!

Battery light comes on after about 5 min... sometimes cycles on and off... eventually stays on and batteries discharge and truck goes dead. This issue existed before I did any work on it


Is the alternator charging on the vehicle? It might be new and work on the bench, but if it is not getting the power it needs to make power on the vehicle then it will not charge. With the vehicle running you should have around 13.5v at the battery at idle. If the alternator is not replacing the power being used out of the battery it will act exactly like you have described.

Alternator checks out good and battery checks out good but alternator does not charge battery is there somethin g else I can check


You have to make sure that you are getting power to the alternator. It could be something as simple as a blown fuse in the power distribution center.

03 escalade won't start or turn over


Do you have power?
battery might be drained cause your alternator is not charging anymore, 2003, seems about time for a new alternator, those vehicles consume lots of power cause pretty much everything is electric, lots of motors and servos, so they depend a lot on a good power source from the battery. If alternator doesnt charge it, no power...

have power system checked.

Good luck.

Replaced alternator and battery in 2002 Chevy Tahoe. Battery voltage remains between 9 and 14 (leaning more towards 9 and at times falling completely until trucks shuts off)


Hello,
When you say battery voltage how are you testing it? Are you looking at a gauge on the dash? Or are you physically testing it with a multi meter? If the truck is dying and you recently replaced the alternator and battery I would first suggest you to check all them connections again real good. Snug them all up. Check for corrosion and clean as needed. Did you replace the battery and alternator with new/re-manufactured battery and alternator? The alternator needs to put out at least 13.6 volts to charge your 12 volt battery or the battery will not maintain a charge. However the alternator runs the vehicle once it is started. The battery is used only to start the car and then the alternator runs it. So if your vehicle starts and runs and then dies you may have a bad alternator. Check your connections first and then test the alternator with a multi meter. Anything less than 13.6 volt will not suffice. 14+ volts would be the hopeful output of a good alternator.
regards, Tony

My car won't start, you hear one click, but nothing, we have to jump it to get to start. The alt. and the batt. and the starter work fine.. Plus our headlights don't work.


If the vehicle need to be jumped then the battery is too weak to start the car.
1. replace battery
2. with good battery start car and check charging system If voltage reads below 13volts possibly the alternator is bad.

Check bulb in headlight ( do not touch the glass part of the head lamp)
a good way to check is replace one with a new one see if it comes on.
If not check fuse for the headlamps ( I am assuming you are talking about low beams)

How to check truck altornator


start engine unhook positive cable if it dies its bad alternator or fuesable link between batt and alternator also a volt meter will tell u if its charging a good alternator will charge 13.50 to 14 volts

All gauges went dead while driving, lights progressively dimmed and finally engine quit.


Your alternator died. You drove until your battery died also. You need a new alternator and a new battery. You might be able to get away with just charging your battery. Do Not jump start the vehicle and let the new alternator try to charge the old battery! Take the battery to a service station for testing and a charge. Install the new alternator and then install the charged battery not vice versa and you'll be fine.

New alternator didn't charge battery. (2VDC


As the car re-started, the battery is not flat.
The voltages measured indicate a problem with either the power or ground connection in the circuit between the alternator and the battery.

You likely have a intermittent / poor ground connection somewhere in the power system.
Check battery terminals are clean and firmly attached.
Check battery cable and alternator ground connections are intact and in good order.
