Each fuse is designed to handle a specific amount of current, and if the current exceeds this limit, the fuse will blow (or melt), breaking the circuit and preventing further damage. Prevent Electrical Fires: By disconnecting the circuit when there’s an overload, fuses help prevent overheating and potential electrical fires. This is crucial for safety, as electrical faults can lead to dangerous situations. Safeguard Components: Fuses protect sensitive electrical components and systems within your vehicle, such as the radio, headlights, and air conditioning. Without fuses, these components could be damaged by power surges or short circuits. HOW THEY WORK Current Flow: Electrical current flows through the fuse, which contains a thin metal wire or strip designed to handle a certain amount of current. Overload: If the electrical current exceeds the fuse’s rating, the metal wire or strip inside the fuse will heat up and eventually melt or break. Circuit Interruption: Once the fuse is blown, it creates an open circuit that stops the flow of electricity. This protects the rest of the vehicle’s electrical system from damage. Replacement: After a fuse blows, it needs to be replaced with a new one of the same rating to restore the function of the affected electrical component. TYPES Blade Fuses: These are the most common type and are used in modern vehicles. They have a plastic body with two metal prongs that fit into a fuse holder. Glass Tube Fuses: These are older and less common in modern vehicles but are still used in some applications. They are cylindrical with metal end caps and a glass or plastic body. Ceramic Fuses: Similar to glass tube fuses but with a ceramic body. They’re used in high-current applications. Mini and Maxi Fuses: These are variations of blade fuses, with mini fuses being smaller and maxi fuses being larger to handle higher currents. RATINGS Fuses come in various ratings, typically measured in amperes (amps). It’s essential to use a fuse with the correct rating for each circuit to ensure proper protection. Using a fuse with too high a rating may not protect the circuit effectively, while a fuse with too low a rating might blow frequently, causing inconvenience. In summary, automotive fuses are vital for protecting your vehicle’s electrical system from overloads, preventing damage to components, and ensuring overall safety. § Socials § Website: https://www.girliegarage.com Facebook: https://www.facebook.com/GirlieGarage1 Instagram: https://www.instagram.com/girliegarage/ TikTok: https://www.tiktok.com/@girliegarage Due to factors beyond the control of Girlie Garage, it cannot guarantee against unauthorized modifications of this information, or improper use of this information.

Automotive electrical safety is crucial for anyone working on or around vehicles, whether you're a professional mechanic or a DIY enthusiast. Here are some general safety guidelines to keep in mind: If you want to support Girlie Garage: https://www.patreon.com/girliegarage 1. Disconnect the Battery Always disconnect the negative terminal of the battery before working on the vehicle's electrical system. This minimizes the risk of electric shock, short circuits, or accidental activation of electrical components. Be cautious of vehicles with dual batteries or hybrid and electric vehicles, which may have higher voltage systems. 2. Beware of High Voltage Systems Modern vehicles, especially hybrids and electric cars, contain high-voltage components (e.g., the powertrain and battery packs) that can be deadly if mishandled. Use insulated tools and wear protective gloves specifically rated for high voltage when working near these components. Always follow manufacturer-specific safety protocols, as these systems can hold a dangerous charge even after being powered down. 3. Use Proper Personal Protective Equipment (PPE) Wear safety glasses to protect your eyes from sparks or debris. Insulated gloves are essential when working around live wires or high-voltage systems. Ensure you're wearing clothes that cover your skin and are not conductive. 4. Avoid Metal Jewelry Remove any metal jewelry (like rings, watches, and bracelets) when working around automotive electrical systems. Metal can conduct electricity and lead to serious injuries or burns if it comes into contact with a live circuit. 5. Inspect Tools and Equipment Make sure all tools are properly insulated and in good condition. Tools with damaged insulation can conduct electricity and increase the risk of electric shock. Use a multimeter or other appropriate testing equipment to check circuits for live current before handling wires or components. 6. Know Your Vehicle's Wiring Diagram Always refer to the vehicle's wiring diagrams and service manuals before attempting any repairs or modifications. This helps avoid cutting or damaging critical wires and helps identify circuits with constant power, even when the ignition is off. 7. Avoid Short Circuits Be cautious to avoid creating short circuits, which can damage the vehicle's electrical system and potentially start a fire. Avoid bridging gaps between live circuits and grounding points unintentionally. 8. Work in a Well-Ventilated Area Batteries can emit hydrogen gas, which is highly explosive. Ensure the work area is well-ventilated to prevent gas buildup, and avoid sparks or open flames near the battery. 9. Beware of Capacitors Many automotive components, like airbag control modules or electronic control units (ECUs), contain capacitors that can store electricity even after the battery is disconnected. Wait a few minutes after disconnecting the battery before handling these components. 10. Follow Manufacturer Instructions and Use OEM Parts When replacing or repairing electrical components, use OEM (Original Equipment Manufacturer) parts and follow the manufacturer’s instructions to maintain the vehicle's safety standards. 11. Never Bypass Fuses Fuses are critical safety components designed to protect the electrical system from overcurrent conditions. Never replace a blown fuse with one of a higher amperage or bypass it with metal. 12. Properly Ground the Vehicle Ensure the vehicle is properly grounded to avoid static electricity buildup, which can cause an electrical spark and potentially ignite fuel vapors or other flammable materials. § Socials § Website: https://www.girliegarage.com Facebook: https://www.facebook.com/GirlieGarage1 Instagram: https://www.instagram.com/girliegarage/ TikTok: https://www.tiktok.com/@girliegarage Due to factors beyond the control of Girlie Garage, it cannot guarantee against unauthorized modifications of this information, or improper use of this information.
