What does “Service Battery Charging System” mean?

You get into your car, and everything looks to be in order until you turn the key and the engine refuses to start. Then you see a warning light and are perplexed as to what it means, and now you’ve ended up here reading this article. 

What does a service battery charging system mean?

When the service battery charging system warning light illuminates, it means that the battery’s charging system is malfunctioning and must be fixed immediately.

What is a service battery charging system?

Every vehicle has a set of electronic components, such as lights, an audio system, and so forth. And, service battery charging systems have two primary functions. The first is to supply electrical energy components such as radio and light. The second function is to charge the battery while the engine is running.

Car’s charging system consists of the following parts:

  • Alternator: The alternator is in charge of maintaining the vehicle’s battery charge. In other words, the alternator charges the battery while the engine is running.
  • The electronic control unit: This charging system component determines how energy should be distributed throughout the vehicle. Another crucial role of the electronic control unit is to decide whether or not to charge the battery.
  • Battery: This is one of the main components of the charging system. When the engine is running, the alternator’s responsibility is to charge the battery.  On the other hand, the battery will provide power to the aforementioned electrical components when the engine is not running.
  • Wiring: After introducing you to the three primary components of the vehicle’s charging system, we’ll explain wiring. The wiring system connects the alternator, the electronic control unit, and the battery through a network of wires.

Causes of charging system failure in your car

These are the potential causes of charging system failure in the car:

Snapped belt

The alternator and crankshaft are connected via a belt. A torn belt can cause your vehicle’s charging system to fail, and by replacing it, you will turn off the battery charging system warning light.

Burnt regulator and damaged diode plate

This is the most common cause of charging system failure. Poor wiring between charging system components can result in a short circuit. A short-circuit can lead to the electronic control unit and rectifier diodes on the rectifier diodes overheating and catching fire. In this case, you should replace this unit with a new one and then correct the wiring between new components.

Damaged stator

Due to the increased heat and temperature generated by an alternator overload, the stator may catch fire. In order to understand why alternator overload occurs, it is necessary to go into more detail. There are a number of possible causes for this, including a battery of low quality that has to be recharged frequently or an alternator that has simply been worn out over time.

Damaged rotor

Let’s take a look at what the rotor does in a car engine. The rotor is connected to the crankshaft. Mechanical energy generated by the crankshaft rotor begins to spin and generates a magnetic field through transmission. This magnetic field eventually generates current for the stator. Due to installation mistakes, the rotor may be broken, resulting in the battery charging system lighting up.

Alternator dysfunction

As previously mentioned, the alternator’s primary function is to recharge the battery. Therefore, if the alternator is unable to convert mechanical energy to electrical energy, the battery will remain discharged.

Dead Battery 

When the battery runs out, there are two primary situations. One is that the battery is incapable of storing electricity. You should replace your battery in this situation. Another possibility is that there is a problem with your car’s alternator, which is responsible for charging the battery while the vehicle is running.

Wiring problems 

If you’ve ever noticed a problem with your car’s wiring or are aware of a problem with power transmission, the battery charging system light is almost certainly the reason. This is the simplest problem to address unless the short circuit resulted in the electronic control unit being fried.

 How to do a simple charging system check

You’ll need to purchase a battery tester to test your charging system if you don’t already have one. There are eight straightforward steps to follow:

  1. Remove the key from the ignition switch.
  2. Connect the red clamp to the positive terminal on the battery of your car.
  3. Connect the black clamp to your battery’s negative terminal.
  4. Tap the Menu and press enter.
  5. Choose the correct answer: “In the vehicle” if the battery is still attached to the vehicle, or “Out of the vehicle” if it is not.
  6. Now, choose a battery type. You have a choice of “Acid lead, AMG, or Gel battery.”
  7. Find out cold-cranking Amp CCA, Which is on the top of your battery.
  8. Hit enter and get results.

The meaning of results shown by the battery test device

The result of the battery test device could be:

  • Good battery: The battery is healthy and works properly
  • Good recharge: the battery is still healthy, but the current is weak, and it needs to be recharged
  • It is recommended to unplug the battery and retest it “Out of the Vehicle” before replacing it. If the result remains the same, replace the battery.
  • Bad cell: The battery is defective or damaged, and you should replace it with a new one.

Is it safe or dangerous to drive my car with the battery light on?

Driving a car with the battery light on is risky, as it indicates a problem with the alternator, battery, or wiring. Driving with these issues can cause the car to shut down, resulting in a plethora of problems, especially if you’re on a road trip. Therefore, we recommend that you test the battery and alternator with the battery test device before you hit the road or take your car to an auto clinic.

 Conclusion

If you own a contemporary automobile, you should pay special attention to the service battery charging system since these vehicles are extremely sensitive to the battery’s and electrical system’s poor performance. Keep in mind that if you ignore any sign of an automotive problem, you will find yourself in hot water down the road.
