Automotive Fuse
A safety device that protects electrical circuits from excessive current.
Automotive fuses melt when current exceeds their rated limit, breaking the circuit to prevent damage or fire. Fuses come in various types blade, glass, or micro and ratings from 5A to 100A. Technicians check for blown fuses using a test light or multimeter. Always replace fuses with identical ratings to avoid wiring damage. Understanding fuse diagrams is key for diagnosing electrical problems safely. Keeping spare fuses is standard practice in any workshop or vehicle toolkit.
