FAQs

  • The most common reason why a car will not start is a bad or dead battery. However, there are several other possibilities too. If you are having trouble getting your vehicle started, give STW Auto Care a call at 732-484-2189. Our auto repair professionals will try to help you diagnose the issue, which could be one of these problems:

    • Failing alternator

    • Starter motor

    • Ignition switch malfunction

    • Bad spark plugs

    • Cracked distributor cap

    • Broken timing belt

  • Mixing up negative and positive cables is the most common mistake. When you mix up the negative and positive cable it ruins your car's alternator. Just remember black to negative and red to positive. Other common mistakes are using cheap cables that don't conduct properly, letting the cables swing and become detached, touching the clips together, and ignoring cracks in your battery or dirty battery terminals.

  • Clicking noises upon turning the key are a classic sign of starter failure. However, this isn't the only clue. A dying starter might remain completely silent or offer subtle warnings through whirring or grinding sounds before finally giving up the ghost.

Understanding your Car’s electrical system

Your vehicle’s electrical system is one of its most vital components, responsible for starting the engine, powering essential features, and ensuring smooth operation. At STW Auto Care, we specialize in diagnosing and repairing electrical issues to keep your car running safely and efficiently.

How Does Your Car’s Electrical System Work?

The electrical system consists of three main components:

  • Battery – Provides the initial power needed to start the engine and supplies electricity to accessories like lights, radio, and power windows.

  • Alternator – Recharges the battery while the engine is running and powers electrical systems. A failing alternator can lead to dimming lights or battery drain.

  • Starter – Uses electrical power from the battery to start the engine. If your car won’t start or makes a clicking noise, the starter may be the culprit.

Beyond these core components, your vehicle’s electrical system also includes sensors, fuses, relays, and complex wiring that control everything from the air conditioning to advanced driver assistance systems.

Common Signs of Electrical Problems

If you notice any of these warning signs, your vehicle may have an electrical issue:
✅ Dim or flickering headlights
✅ Difficulty starting the car or a dead battery
✅ Burning smell or blown fuses
✅ Power windows, locks, or radio not functioning properly
