Your Electrical System

Your vehicle relies on a complex system of electrical components in order to work properly. You should have your system inspected regularly for signs of damage caused by:

• Salt
• Dirt
• Moisture
• Loose connections
• Rust and corrosion

Undetected electrical problems can quickly worsen, leading to expensive repairs or even the possibility of finding yourself stranded.

Fortunately, it's easy to protect yourself from both these situations: have your electrical system inspected regularly, and undercoat your vehicle.

Your Electrical System

Your battery provides the power to start your vehicle's engine. It also runs any electrical accessories, such as the lights, radio/stereo and even your cell phone if you have it plugged in.

Your battery is able to produce this power by creating an electrochemical reaction within itself. This reaction also produces an explosive gas; that's why it's important to keep the vents on the sides of your battery clean at all times so this gas can safely disperse.

You can expect your battery to last two to three years; however, conditions such as climate extremes, corrosion and damage to the electrical system can adversely affect its lifespan.

If you need help finding the right replacement battery for your vehicle, just talk to your local Coast Tire & Auto Service technician.

The name says it all: your vehicle's starter motor starts your engine. Voltage to the starter is supplied directly from the battery and is controlled by the ignition switch inside your car.

Problems with the starter can also affect your battery and alternator. If you're having trouble starting your car, just contact your nearest Coast Tire & Auto Service professionals. We'll locate the problem and suggest a fast, affordable solution.

Alternator

Your vehicle's alternator recharges your battery and powers the electrical system when your vehicle is running. Problems with your alternator can affect accessories such as wipers, headlights, etc., or make your engine suddenly stop running.

Voltage Regulator

Without a voltage regulator, the alternator will always operate at its highest output, damaging the battery and other electrical components. The regulator controls the alternator's output and prevents over- or under-charging of the battery.

If your electrical warning light comes on, that means you are having problems with either your alternator or voltage regulator. Bring your vehicle in for inspection right away, before the problem becomes serious.

Your vehicle's controls (such as fuses, switches, capacitors, and transistors) start, stop and redirect the flow of current in your vehicle. Many of them operate by physical movement, so it is important that they are kept clean and free of corrosion.

Your lights, wiring and switches include:

• headlights and dimmer switches
• stoplights and taillights
• parking and courtesy lights
• side marker lights
• license plate light
• instrument panel lights
• horn
• directional (turn signal) lights
• Interior and dashboard lights
• Hazard warning flashers

If electrical currents run too high, they can fuse or melt your electrical components. Your vehicle is protected from this danger by a system of fuses and circuit breakers that are designed to detect abnormally high currents and stop them before they can damage your engine.

Important safety point: a blown fuse or circuit breaker is an indication of an underlying problem. Identify and correct that problem before you replace the blown parts.
