WHAT IS A CHARGING DYNAMO (ALTERNATOR)?

The system that converts the motion created by the engine into electrical energy is called the alternator (alternator). The alternator generates electricity, allowing the battery to be charged and meeting the needs of the equipment. While the engine is running, the battery delivers a lot of current and must remain charged continuously. The alternator can charge the battery with an average voltage of 12.9 - 14.9 volts. The capacity of the alternator varies according to the current (ampere) produced. When a malfunction occurs in the charging (alternator) system, the battery charge warning lamp on the instrument panel will also turn on. In this article, you can learn about many topics such as what is an electric dynamo, charging engine, alternator fault detection, alternator repair and alternator failure.


The Task of the Charger;

It feeds the electrical receiver while the engine is running.

Recharges the battery while the engine is running.



Why the Charger (Charger) Fail?

Parts in the Alternator such as bearing and coal have a certain lifetime. Hot, dusty and oily operating conditions reduce the life of the bearing.

There are two important causes of bearing failures. The first is the tension of the alternator's belt and the use of electrical devices that force its capacity.


What are the Charger Failure Symptoms?

Although the electrically induced alternator failure is not very visible, it can be noticed by the signals given by the vehicle.

Warning Signs (Dashboard)

Chargers operate in the 13 or 14.5 volt range. In situations that require excessive power, such as turning on the headlights, activating the wipers, radio, heated seats or defroster in the window, the alternator operates with a high capacity voltage. If the voltage does not meet the needs of the system, it will go beyond the upper or lower limit and this change will cause the warning light to turn on.


Dim Lights

This effect is seen in the electronic system when the alternator, which provides the electricity need of the vehicle, begins to lose electricity.


Dim or too bright headlight and indicator lights

Speed ​​and rev indicators stopped

Electric windows slow when rising and falling

Appearance, Sound and Smell

This stated situation is decomposed as signals from our senses. These signals are not as obvious as incoming warnings, but indicate to the driver that something is wrong.


Battery Dead

To find out if the problem is with the battery or the alternator, you need to start your vehicle and remove the battery cables as quickly as possible and wait. If the problem occurs in the alternator, the vehicle will stop after a while. If the vehicle is still running, it is understood that the problem is caused by the battery.

Broken or Loose Connections

The alternator transmits electricity through large cables and small wires. Problems in the connection of wires or cables can reduce or stop the passage of electricity completely. In some cases, more energy consumption is required to overcome the resistance of the alternator, however, it may appear as bright light.

How is the alternator tested?

Alternators (Lichtmaschine, Alternator) are auxiliary units that play an important role in motor vehicles. It functions in charging the battery and generating the electrical energy required by the car. In modern charging dynamos, the magnetic flux created by the rotor causes induction in the 3-phase winding in the stator and 3-phase alternating current (AC) electrical energy is produced. Thanks to the rectifiers, this 3-phase electrical energy is converted to direct current (DC) and transferred to the vehicle's electrical system. The stator consists of thick and solid copper wires and is durable because of its immobility. For this reason, the parts that can malfunction in the alternator are as follows: Pulley bearing (front)

2. Stator bearing (rear)

3. Rectifier

4.Induction coals

When the rectifier fails, it should be replaced with a new one because it is closed circuit. Induction coals can generally last as long as the life of the vehicle, but may need to be replaced in cases such as excessive wear and early wear. Bearings are likewise covered with a sealed grease cover and can last as long as the life of the vehicle.


Good workmanship and the best quality parts should be used in the repair of the alternator, which is considered to be the liver of the vehicles, so to speak. For this reason, it is necessary to use quality and technological test equipment in the alternator repair process.
