How the alternator is tested?
If the charging system fails the test, your mechanic will need to do further diagnostic to see if it's the alternator or something else causing the problem. Other charging system problems include a loose drive belt, faulty wiring or blown fuse, defective ignition switch, etc. Read also: How to check a fuse in a car.
Checking the alternator output voltageChecking the alternator output voltage with a multimeterIf no charging system tester is available, your mechanic can do a simple voltage test. The test involves checking the battery voltage with the engine off and with the engine running. The battery voltage should increase once the engine is started, as the alternator supplies additional power. If the battery voltage does not increase once the engine is started, there is a problem with the charging system.
How Does the Alternator Work?
The functioning of an alternator is straightforward. A serpentine belt that rests on a pulley is attached with an alternator. When the engine is ignited, the pulley moves and rotates the rotor shafts attached to the alternator. The rotor is an electromagnet with two revolving metal slip rings and carbon brushes attached to its shaft. Due to the rotation, a small amount of electricity is supplied to the rotor, which is conducted to the stator.
The magnets on the rotor are placed in such a way that they pass over the copper wire loops in the stator. This creates a magnetic field around the coils. When the rotor spins, the magnetic field is disturbed, and this, as a result, generates electricity.
However, the current generated is AC has to be converted to DC before use; therefore, it is channeled to the alternator’s diode rectifier. The rectifier changes the two-way current into a one-way flow-direct current. The voltage then passes on to the voltage regulator that steps up or steps down the voltage to match the needs of different units of the car.
