Practical Tips for Maintaining a Truck's Electrical System
Of the four electrical components, the starter motor, battery, alternator or engine, the alternator is the main power source for the truck when it is running. The alternator is an important part of the electrical system that provides electrical power to the vehicle. Without it, and other important elements such as the starter and battery, the vehicle will not start. If the alternator has a problem many of the components are not operating properly.
“By understanding how the truck's electrical system works, you can prevent premature wear on other components. The electrical system for the starter motor, battery and alternator functions to start the engine, and provide electrical power to all electrical devices such as radios, lights, power windows, ignition keys, windshield wipers, air conditioners, and so on," explained Aferi Yusrianto, Head of Duta Unggul Workshop. Krian.
The starter motor functions to convert electrical energy into mechanical energy through the relay and starter solenoid. Then provide an electric current to the flywheel to start the engine and then start the vehicle. “This is how it works, the ignition is turned, and the battery will send a low-voltage electric current to the starter relay. The starter relay energizes the solenoid, which converts electrical energy into mechanical energy. Mechanical energy drives the flywheel, then the engine starts and the starter turns off. A problem that may occur with the starter is if the starter's live contact does not activate immediately. Then a clicking sound is heard when turning the ignition key. Another reason, smoke appears from the starter circuit, "explained Aferi.
The battery is considered the most important electrical component because it functions to start the vehicle. “These devices also store energy when the engine is off, which provides electrical power for devices such as radios, and fans when the truck engine is on and off. Indications that the battery is damaged are the engine is difficult to start, the battery light indicator is on, there is a scorched smell because the battery material is leaking, "explained Aferi.
The alternator is the main power source while the truck is running. When the engine is running, the alternator is what keeps the vehicle from turning off. The characteristics of a problematic alternator are the sound of friction when the engine is running, the battery is dead, the engine is losing power and the lights are dim or flashing.
Over time, the age of the vehicle, mileage, and driving style can affect the electrical system and prevent it from operating normally. “With regular maintenance, it will prevent potential problems before they turn into big problems. The most important thing is to check and clean the battery cables, check for loose plugs and cables and make sure all the lights are off when the truck engine is off," concluded Aferi.
