How to make your alternator last longer

Often an alternator fails prematurely when a protective engine undercover or shield is damaged or missing. This happens because water splashing from the road gets inside the alternator and causes it to wear faster.


If your engine undershield is damaged, have it replaced to keep the engine compartment clean and dry. A coolant or oil leak can also damage the alternator. Similarly, if you have to shampoo the engine compartment, the alternator must be protected from water and detergent.


How an alternator works, common problems

Alternator cutawayAlternator cutaway. Image courtesy of Robert Bosch GmbHA typical AC car alternator has two windings: a stator (stationary outside winding) and a rotor (rotating inner winding). A voltage supplied through the voltage regulator to the rotor winding energizes the rotor and turns it into a magnet. The rotor is rotated by the engine via a drive belt.


The magnetic field produced by the rotating rotor induces AC electric current in the stationary stator winding. Diodes are used to convert AC current into DC current used in the vehicle's electric system. The output voltage is controlled by the voltage regulator (photo below). Typically, a voltage regulator is built-in into the alternator.


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.


Wiring Connections

Since an alternator is connected to so many components, it exhibits a complex wiring system. The main wirings include the exciter wire, positive and negative cables. Exciter wire is connected to the L terminal of an alternator and is used to turn on the voltage regulator. Excitor wire is needed to generate the voltage required for the alternator to start running.
