Experienced mechanics share their insights in answering this question :
The voltage output of the alternator should be tested at the battery terminals while the engine is running. You should read output of 13.8 volts on up to maybe 14.4 volts but the value (and range, which is dependent on engine RPM) will depend on your Factory Service Manual Specification which the Mechanic will have on hand. You also have to look at the output while running various circuits. It could be that there is a short in one of those circuits which causes battery voltage to drop below the threshold at which the warning light will set. My initial suspicion would be the alternator is simply out of spec. What I would recommend is having a certified professional from YourMechanic perform an inspection of your battery and charging system which will identify the root cause of this issue you are having. Once the cause is understood, he or she will explain the repair strategy and cost. Please let us know how we can assist you further or if you have additional questions.
How to Identify and Fix Common car Problems ?

It is possible that the problems that you have been experiencing with the bad alternators have damaged the battery causing it to be weak. This would make the Battery Light come on. It is also possible that there is a problem with the fusible link or the alternator fuse for the charging system.
The car battery light might come on for many reasons, but the most common reasons are: An old car battery. Car battery connections that are corroded. Car battery cables that are misconnected.
The Chevy service battery charging system warning comes up when there`s a problem with your vehicle`s charging system. This is usually caused by one of these issues: The connections between the alternator and battery are corroded. The connections are loose, or one of the wires is broken.
A bad battery won`t usually harm your starter or alternator, however, since both of those components get their voltage directly from the battery, if the battery is underperforming, both the alternator`s and starter`s performance will be affected as well.
The message can reset by itself, but the car needs to sit undisturbed for at least eight hours. Perhaps with your work/driving schedule the car doesn`t sit long enough. Q: I have a headlight that is dim.
An illuminated battery indicator can be caused by a number of issues, including: A loose or corroded battery cable. A problem with the alternator or voltage regulator. Damaged cells or plates inside the battery.
Driving with your battery/check charging system light illuminated could leave you stranded. If your vehicle has a failing battery, faulty alternator or bad wiring, it could stop working at any time. Make an appointment with your mechanic before your car puts you on the side of the road.
In most cases, a set of sticking or worn alternator brushes, a broken field control wire, corroded battery cables or a bad connection at the alternator or battery will cause an intermittent low-state-of-charge problem.
LOSS OF POWER. Of course, losing power is the number one symptom of charging system failure. You might experience problems with dim or flickering lighting inside cabin or your headlights may become dimmer too. Certainly you`ll not be able to start the car if you lose power totally.
A mismatched battery/alternator combo could cause your alternator to overheat and shorten its life.
Put simply, your alternator keeps your car battery charged, allowing you to turn on your car and use electronic accessories such as your headlights and radio. If you`re experiencing car alternator problems, you may find that your car won`t start or stay on for more than a few minutes.
Like desktop computers and most other electronics, disconnecting the battery cable for a short period will not fully reset your ECU due to the residual power remaining in the circuits.
The exact amount of time that your car will be able to function with the battery light on depends on many factors, but assuming that the alternator is the issue (this is the most common issue) it is likely that your car will lose battery power after 30 minutes to an hour of driving.
A blown fuse could be a cause of the battery light to come on. Excessive voltage in the electrical system can blow the fuse and prevent charging of the battery. A electrical technician can replace the fuse quickly and it an inexpensive fix.
Probably, the most common symptom associated with a bad regulator is flickering, dimming, or pulsing lights. To be more specific, you may notice that the vehicle`s: Headlights fluctuate between bright and dim, without you doing anything. High beam isn`t working as expected.
The red battery light could indicate a problem with the alternator, battery or other parts of the electrical and charging system in the car. It could be a minor problem such as a malfunction rectifier unit, blown fuse or cabling short circuit.

You have a new alternator, so if your battery is bad, it won`t hold the charge from the alternator. The problem could still be a defective alternator or improper installation. A fuse could also be the cause. If you still have power (headlights still work) the problem is in the fuel or ignition system.

An effective method to determine whether it`s your battery or alternator that`s gone bad is to connect jumper cables from a running vehicle`s battery to yours. After a few moments, try starting your vehicle. Once it`s started, remove the jumper cables — if your engine stalls, your alternator has probably gone bad.

I got a new battery new alternator put in but my battery just gets drained I keep having to buy new batterys
ANSWER : This may be a sign of a failing voltage regulator or potentially a bad grounding problem causing a draw on the system. The voltage regulator is a unit that regulates the charging of the battery by the alternator. Often times this will result in the alternator allowing too much power to be delivered to the battery resulting in damaging wires and prematurely sometimes destroying the battery. In other cases it may result in the alternator not supplying enough power to the battery, resulting in undercharging the battery or not charging it at all. In either case, I would recommend having an expert from YourMechanic come to your location to diagnose your vehicle’s charging system.
my battery kept draining until i bought a new alternator and battery. i have tightened the belt on the alternator but it still die
ANSWER : Hi there. The best way to diagnose why a battery would constantly drain is to review it’s job and how it is recharged. The battery is responsible for powering all electrical systems until the vehicle is started. At this point, the alternator takes over and also continually charges the battery while the vehicle is in use. A battery will drain when one of two things occurs. First, a battery will drain if it is constantly in use; supplying power to an electrical component even if the key is not in the ignition. Second, the battery will eventually die if the battery is not being charged frequently. However, since this is happening every two days, my initial thought would be that some electrical component on your 86 Olds is continuing to draw power from the battery. This is known as a parasitic drain. The best way to determine the source of this battery issue is to have one of our professional mobile mechanics come to your location and complete a battery will not hold a charge inspection.
We have a new battery, new alternator, new coil pk, new master fuse and the car still won’t hold power.
ANSWER : Hi there. The only thing that I could think possible is causing your problem is that something may not have been correctly installed while your son was completing this maintenance. However, if your engine was difficult to start before this service, it’s possible there are different components that are damaged that simply didn’t resolve the issue. The only way of knowing what is going on with your Trailblazer would be to have one of our mobile mechanics in your area come to your location and complete a car is hard to start inspection.
Just put a new carburetor, battery, starter relay, alternator, car stalls out while driving and battery dies when restarted
ANSWER : The battery should be load tested. Simply charging the battery or measuring voltage is not adequate. Measure charging output, too. You want to confirm that the ignition system, including for instance the ignition coil and ignition switch, are not intermittently cutting out. Coils can fail as temperature rises (resistance increases with temperature) so if you run the car for a while and all of a sudden it quits, measure the resistance of the coil windings to see if that provides a clue. Apart from that, the ENTIRE primary side ignition circuit has to be checked, using voltage drop testing (and testing of the hall effect sensor in the distributor), to rule the primary side in or out. If you want the required diagnostic steps performed by a certified Mechanic, dispatched by YourMechanic right to your location, please request a stalling diagnostic and the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
Battery good, alternator good, brand new alternator cable, still not charging.
ANSWER : Hi There,
The first diagnosis of the bad voltage regulator is likely the cause of your charging system not properly charging the battery. When the voltage regulator is not working properly, this may result in the alternator allowing too much power to be delivered to the battery resulting in damaging wires and prematurely sometimes destroying the battery. In other cases it may result in the alternator not supplying enough power to the battery, resulting in undercharging the battery or not charging it at all. In some cases when a battery is too weak or damaged, it may no longer hold a charge for any length of time, in which case the alternator may be doing its job, but the battery is just simply too weak to hold a charge. In either case, I would recommend having an expert from YourMechanic come to your location to diagnose your vehicle’s charging system.

New battery and alternator but there is still no power in my 204 Xterra onve I turn it off.
ANSWER : Hi there. It sounds like you either have a defective alternator or there is another issue within the circuit for the charging system. I usually start by checking the output of the alternator. If it is not putting out the right voltage or amperage then it needs to be replaced. I would then check to see if the alternator is getting the correct signal to turn on. These would tell me if the output if correct. If the alternator is putting out the right voltage then the positive battery cable may have failed and may have high internal resistance. If you need to have this checked out, consider YourMechanic, as a certified mechanic can come to you to [diagnose why the vehicle is losing electrical power] https://www.yourmechanic.com/services/electric-problems-inspection
Put a brand new alternator in it and new battery and it still does not want to charge the battery is this
ANSWER : Inspect fuse number 11 and 30 in the fuse box. Check the grey fuse link near the starter. If both of these are good then check fuse 19. In fact, its best to check all the fuses for any blown ones. Have the computers scanned to see if the computer has codes for the charging system. The alternator charging is controlled by the computer, and I have found that sometimes aftermarket alternators do not fix the problem. Some vehicles have more factory options for alternators than what the aftermarket offers. If the fuses do not help then you may have to replace the alternator with a dealer supplied one. On some of these vehicles they also had problems with the instrument cluster and connections to the cluster, which could be playing a part. If you cannot find the problem, then have a technician, such as one from YourMechanic, come and check the system for you.
