The heart of a car’s electrical system are the battery and alternator. Together, they supply the vehicle with the electricity needed to power the brain of a car—the engine control unit (ECU). The electrical system also consists of critical components, including:
- Ignition system
- Fuel injection system
- Emissions system
Some modern luxury cars contain more than one hundred individual computers. These are just a few:
- Air bag system
- Antilock brakes
- Antitheft system
- Automatic wipers
- Entertainment system
- Electronic-controlled transmission
- GPS system
- Power/heated seats
- Stability and traction control
At 12 volts, a fully-charged battery stores the electricity necessary not only to power all the above components but, most importantly, to start the car. The batteryconsists of six stacked lead plates immersed in a water and sulfuric acid mixture. Explosive gases escape through the battery cover vents, so take care when charging or jump-starting batteries. “Maintenance-free” batteries replace sulfuric acid with a gel, which is safer.
A dead or dying car battery is one of the most common problems motorists face. In addition to possibly preventing the car from starting, a poorly performing batterycan affect the operation of almost any vehicle system. Use only high-quality batteries and replace your battery at the end of its useful life as part of proactive, preventive maintenance.
is a magnet rotating inside looped copper and an iron core. It produces electricity that is delivered to the battery. When the engine is running, a drive belt spins the alternator pulley. Depending on its size, an alternator can generate between 1.5 and 2.5 volts, resulting in a total electrical system output of 13.5 to 14.5 volts. To prevent overcharging and damaging the battery, a voltage regular keeps total system output below 14.5 volts.
When you turn the ignition key, electrical current is sent from your battery directly to the starter, which cranks the engine’s flywheel and moves the pistons. At the same time, the battery sends electrical current to the ECU, which signals the fuel injection system to inject gasoline mixed with air into the engine. The ignition system then ignites a spark to begin combustion.
Even before the car is started, electric power is sent to the fuse box, which activates accessories including lights, power windows, and the radio. Accessories that draw heavy amperage, such as aftermarket stereos and entertainment systems, can overload batteries and alternators, wearing them out twice as fast as normal.
Some newer lighting systems contain light-emitting diodes (LEDs), which are tiny individual lights that can burn several times longer than traditional bulbs, while requiring a fraction of the electrical energy. LEDs are also much brighter, allowing automakers to improve the quality and safety of nighttime driving.
Why is it important to get my vehicle’s electric system serviced?
There are dozens of electrical components needed to route power in your vehicle’s electrical system and these can vary greatly according to vehicle make, model and age. Your electrical system includes your vehicle’s battery, alternator and starter. Many new vehicles also feature sophisticated computer systems that affect functions like steering, brakes, sensors, and more. All of these electrical components make it difficult to diagnose the cause of vehicle electrical problems, but most begin and end with your battery.
How do I know when it’s time to have my vehicle’s electrical system serviced?
Batteries usually last between three and seven years, so it’s a smart idea to replace yours every four years as a safety measure. Have your vehicle’s electrical system checked immediately if:
- Your vehicle won’t start – you turn your key and hear clicking, grinding, or no sound at all
- Interior or dashboard lights do not illuminate properly
- Your vehicle runs well, but the headlights dim while you’re traveling at low speeds, or idling at a stop
