Applications in Automotive Systems

This fusible link is commonly used in the following vehicle circuits:

• Interior Lighting: Dashboard illumination, dome lights, and reading lamps.
• Power Accessories: Power windows, door locks, and seat adjustment mechanisms.
• Electrical Modules: Control units for infotainment, climate control, and engine management that require a reliable fuse to protect sensitive electronics.
• Auxiliary Systems: Headlights, fog lights, and other auxiliary lighting systems where a 20 A rating provides adequate protection without compromising performance.

Installation Guidelines

Installing the Bosch Fuse Gelb is straightforward and follows standard automotive fuse replacement procedures:

1. Disconnect Power: Safely disconnect the vehicle’s battery or remove the relevant circuit breaker to eliminate electrical hazards.
2. Locate the Blown Fuse: Identify the fusible link that has failed, typically indicated by a broken metal filament inside the yellow housing.
3. Remove the Old Fuse: Gently pull out the defective fuse using a pair of needle‑nose pliers or a dedicated fuse removal tool.
4. Insert the New Fuse: Align the new Bosch Fuse Gelb with the terminal slots and push it firmly into place until it clicks, ensuring a secure connection.
5. Reconnect Power: Reconnect the battery or circuit breaker and test the affected system to confirm proper operation.
