Product Overview
The Littelfuse AGA2 Ignition Fuse is a critical component designed for automotive electrical systems. This fuse provides essential overcurrent protection, safeguarding electrical circuits and components from damage due to excessive current flow. It is specifically engineered for ignition systems, ensuring reliable operation and protection.

Setup and Installation
Proper installation of the AGA2 Ignition Fuse is crucial for its effective operation and the safety of your vehicle's electrical system. Always consult your vehicle's service manual for specific fuse box locations and fuse ratings.
- Safety First: Before beginning any work on your vehicle's electrical system, disconnect the negative terminal of the battery to prevent accidental short circuits or electrical shocks.
- Identify Fuse Location: Locate the fuse box in your vehicle. This is typically found under the hood, inside the passenger compartment (e.g., under the dashboard or in the glove box), or in the trunk. Refer to your vehicle's owner's manual for the exact location.
- Identify Correct Fuse: Consult the fuse diagram, usually located on the fuse box cover or in the owner's manual, to identify the specific fuse for the ignition circuit. Ensure the replacement fuse matches the original fuse's amperage rating (e.g., 2A for AGA2). Using a fuse with an incorrect rating can cause damage or fire.
- Remove Old Fuse: Use a fuse puller tool (often found in the fuse box or vehicle toolkit) or small pliers to carefully remove the blown or faulty fuse. Avoid using metal tools that could short circuit.
- Insert New Fuse: Insert the new Littelfuse AGA2 Ignition Fuse firmly into the empty fuse slot. Ensure it is seated correctly and securely.
- Reconnect Battery: Once the new fuse is installed, reconnect the negative terminal of the battery.
- Test System: Start the vehicle and test the ignition system to confirm proper operation.
Note: If the new fuse blows immediately, there may be a short circuit or an underlying electrical issue that needs to be diagnosed by a qualified technician.
Operating Principles
The Littelfuse AGA2 Ignition Fuse operates on the principle of a sacrificial component designed to protect more valuable electrical circuits from overcurrent conditions. When the current flowing through the fuse exceeds its rated amperage (2 Amperes for AGA2) for a specified duration, the metallic element inside the fuse melts, creating an open circuit. This interruption of current flow prevents damage to the wiring, ignition components, and other sensitive electronics connected to that circuit.
- Current Protection: Designed to protect circuits from excessive current.
- Circuit Interruption: Melts and breaks the circuit when current exceeds its rating.
- Safety: Prevents overheating, wire damage, and potential fires caused by overcurrents.
- Application: Specifically used in ignition circuits to ensure their integrity.
Maintenance
Fuses are generally maintenance-free components. However, periodic inspection can help ensure the integrity of your vehicle's electrical system.
- Visual Inspection: Periodically inspect fuses in the fuse box for any signs of damage, such as discoloration, cracks, or a broken filament. A clear fuse body allows for easy visual inspection of the internal element.
- Replacement: Fuses are designed to blow when an overcurrent occurs. If a fuse blows, it indicates an issue within the circuit it protects. Always replace a blown fuse with a new fuse of the exact same amperage rating and type (AGA2, 2A). Never use a higher-rated fuse or bypass a fuse, as this can lead to severe electrical damage or fire.
- Cleanliness: Keep the fuse box area clean and free from debris or moisture to prevent corrosion and ensure good electrical contact.
Troubleshooting
If an electrical component or system (e.g., ignition) stops working, a blown fuse is often the cause. Here's how to troubleshoot:
- Identify the Affected Circuit: Determine which electrical component or system is not functioning.
- Locate the Corresponding Fuse: Refer to your vehicle's owner's manual or the fuse box diagram to find the fuse associated with the non-functioning component.
- Inspect the Fuse:
- For clear fuses, visually check the metal filament inside. If it's broken or melted, the fuse is blown.
- For opaque fuses, you may need to use a fuse tester or a multimeter set to continuity mode to check if the fuse is intact.
- Replace Blown Fuse: If the fuse is blown, replace it with a new Littelfuse AGA2 Ignition Fuse of the identical amperage rating (2A).
- Test the System: Turn on the ignition and test the previously non-functioning component.
- Recurring Blown Fuses: If the new fuse blows immediately or repeatedly, this indicates a persistent electrical problem, such as a short circuit or an overloaded circuit. In such cases, professional diagnosis and repair are recommended. Do not continue to replace fuses without addressing the underlying issue.
