If you look at your car when the ignition is switched on, but before you start the car you will probably see that one of the lights looks like a small battery with a "+" and "-" sign on it, and this is the battery or charging light, and once the car starts up you should All your car lights are lit.
Car battery bulb problems
There are problems with the charging circuit in the car, the problem may be due to the following:
1- The dynamo does not charge the battery. When there is a problem with the dynamo, the battery will not be charged and will deplete quickly, causing the battery bulb to appear on the car's dashboard.
2- There is a defect in the conducting wires for charging, and the electrical wires may be exposed to damages, which may result in them not working or being damaged. Here, the car battery will not be charged, resulting in the appearance of the battery bulb in the car.
3- One of the fingers of the battery may be loose or needs cleaning to isolate the electricity.
4- Damage to the car battery, when the battery is permanently damaged, it must be replaced, then the car engine will not start at all.
The purpose of the battery light
Your car or truck is equipped with a large number of safety monitoring systems that are constantly checked to know what is happening inside the engine with the brakes, and even inside your tires as is the case with the tire pressure management system, and not only is the information stored inside the electronic control unit in your car (ECU ), Which is the main computer or the brain in your car, and there is often light or string of lights on the dashboard that appears when an error is detected in a specific system, such as the braking system or the charging system, for example, this system is very useful for drivers, so if you see a warning light then you know that your car will likely need some kind of immediate attention, even if nothing has broken down completely yet.
Why does the battery light ignite?
This lamp lights up when your generator does not produce electricity and a car is running out of battery power alone, and you can drive a short distance on the battery, especially if you turn off most electrical elements in your vehicle (such as radio, air conditioning, etc.), but there is no A way to know the extent to which you will reach it before it is damaged, so the best thing to do is to draw as soon as it is safe, and unfortunately while this little light is useful in drawing your attention, it is really bad to tell you the exact problem for this reason when you see a light like Battery lighting You have to do a little research or gain some knowledge of the work before you can decide whether to stop by the side of the road and invite to withdraw and continue to a maintenance station or a home and fix the problem yourself.
Initial checks for the car
If you have some experience in car maintenance and are not far from home, you may want to drive your car to the garage and operate it by checking the charging system, usually, the battery check lamp indicates that you need to either replace the generator belt or the generator, but not that quickly, before Doing this continues and checks the battery connections, and the lamp can light up even if your generator belt is intact and the generator is charging well, but battery connections prevent the electrical circuit from properly providing the vehicle's systems with electricity, and even bad ground wires can be sufficient to cause a condition Bad charging and running battery lamp.
And sometimes cleaning the battery connections leads to solving the problem of charging without costing you a penny, or at least no more than one penny, and always remember to look at the least expensive repair option before you dive into big-ticket repairs, and in the case of cleaning the battery terminals, the ounce Prevention deserves a pound.
Check the vehicle charging system
Keep in mind that the battery with overcharging is often the result of leaving the car accessories overnight, or because of a tail lamp or compartment on the dashboard that remains in place, and when the charging system is operating normally, the charge indicator lamp will turn on when the ignition switch is turned on and will exit at Starting the engine, and if the lamp does not turn on, you will need to check the warning light circuit or replace the lamp, instead noise from the generator may occur due to the following components:
1- Incorrect guidance of hoses, wires, or protection against the generator casing.
2- The motor pulley is loose.
3- Loose fixing screws.
4- The diode is faulty.
5- The stator is wrong.
6- Slip the friction ring.
Precautions when checking the car
1- Do not interrupt or interrupt any of the peripheral devices in the charging circuit, except by the instructions of the instructions.
2- Do not attempt to quickly connect the generator by connecting the voltage B + to any of the four-way connector terminals.
3- Never disconnect the output device while the generator is running.
4- Use only approved terminal probe adapters to connect the meter wires and the passage wires to the terminals of the conductor.
5- Using incorrect transformers will damage the terminals and cause a charging system failure or harness test.
