Engine electrical equipment includes units and assemblies responsible for starting the engine and operation of systems connected to the onboard electrical network of the vehicle. They include the starter, alternator, battery, and ignition system.
Important information about engine electrical equipment
- The service life of specific components is determined by the manufacturer of the vehicle. Spark plugs are replaced most frequently, as they are consumable items. Copper, nickel, chrome-nickel, and copper-nickel spark plugs last approximately 20,000 – 30,000 km, platinum — about 60,000 – 70,000 km, silver — 70,000 – 90,000 km, iridium, gold, and yttrium — 70,000 – 100,000 km. The service life of the batteries is 3 to 5 years, while the ignition coils’ service life is —110,000 to 140,000 km.
- Most elements of the engine electrical equipment should be replaced at a repair shop as this work is difficult. For example, the alternator and starter are difficult to dismantle and disassemble. While working on the ignition system and dealing with ignition wires is dangerous without appropriate skills and knowledge.
- You can replace the battery by yourself. This will require a brush and a cleaning agent for the contacts and a wrench for connecting wires to the terminals of the battery.
- It is best to buy the components of engine electrical equipment after diagnosing which system needs to be replaced. Very often, installation of a new component requires replacement of another one. For example, if you are planning to install a new alternator, it is better to buy a drive belt, too. If spark plugs are replaced, it is recommended to buy high voltage wires and ignition coil. Installation of new high voltage wires may be combined with replacement of the distributor cap. You can find all components in the catalogue of our online shop. Get advice from our specialists, find out about promotions, and purchase high-quality equipment at the best prices.
- To ensure electrical equipment works for as long as possible, it is important that all accompanying systems work properly, as their failures are often interrelated. For example, incorrect operation of the alternator means the battery doesn’t get fully charged, which leads to further problems. Numerous unsuccessful attempts to start the engine may burn the starter. Poor quality fuel is often the reason for spark plugs failure.
