The alternator is what is responsible for taking mechanical power from the engine and converting it into electrical power that can go into the battery. The first problem we are going to talk about is alternator issues. The common reasons for charging system failure are….īelow we are going to cover each one in detail, but if you think it is more likely one over the other, then you can jump to that section. Some are easy to check, while others can be more difficult. Now that we got the question of should you keep driving out of the way your next question is probably what is causing the light to come on? Well, there are a variety of things that can lead to the charging system to fail. Possible Problems make Charging System Failure If the light is staying on, then you should pull over in a safe spot and call a tow truck to tow you to the shop to have your vehicle checked out. A car can not go far on just the battery. However, If the light is staying on continuously, then you should not keep driving unless you are close to the shop. That way if the system continues to stop working as you drive, then you will reduce the amount of power you are using. It is a good idea to turn off the radio, AC/Heat, and any other electronic components of your car that aren’t needed. If it is coming on, and then going off, then yes you should be okay to drive to your shop. You may be wondering if you should keep driving then with the charging system light on. Should you drive when Charging System Failure That is because your charging system could go out completely at any moment. Even if this happens, you need to get your car checked out as soon as possible. The light might flicker on the dashboard and then go off. This is a bad thing because if your battery is not charging, then your vehicle might die and lose power.Ī lot of times the charging system won’t go out all at once though. When either of these lights illuminates, it typically means that something is causing your battery not to charge while driving. So, now we can move onto what does it mean when your check charging system light or battery light comes on. What does it mean Charging System Failure You can learn more about what dimming lights means though in this article. That is why flickering or dimming lights can be a sign of charging system problems. The charging system not only charges the battery though, but also helps run your lights, radio, and other electrical parts of the car while the engine is running. These are connected with wires, so wires are also a part of the system. Connected to the battery though is the alternator and electronic control module (ECU). The main parts of the charging system are of course the battery. A particularly negative symptom is its uneven wear caused by, e.g., non-axial position of the poly-v belt (which is highly worn out or incorrectly installed).Causes Of Charging System Failure In Your Car What is a Charging System?īefore going into specific details on each part of the charging system, we are first going to give a rundown of the main components. The alternator pulley wears out over time. It can also be affected by any external contaminants such as liquids or solids. Premature wear of bearings is usually caused by the poor quality of materials used to produce them. The alternator may also break down because of perfectly normal wear and tear of its parts. The causes of failure may also include installation errors. Its failure is most commonly related to the normal wear and tear of the commutator which is the component responsible for current flow. The rotor is powered by mechanical energy from the crankshaft. The current in the stator is generated by a rotor creating a magnetic field. air supply), poor condition of the battery requiring constant recharging by the alternator or the normal wear and tear of the alternator. The excessive load might be a result of many reasons – intensive use of the vehicle devices (e.g. The reason for the stator burning is excessive alternator load which leads to its overheating. The regulator might have been affected by water, oil or other operating fluid leaking from the pipes under the vehicle hood. If the damage is limited to the regulator, and the diode plate remains intact, the probable cause of the fault is liquid ingress. A sudden short circuit may lead to the destruction of the regulator and burning of the rectifier diodes. The problem is the incorrect wiring of the battery. The faults of this component are most frequently caused by installation errors – often occurring during factory installation.
