⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems to avoid shocks or shorts.
•Allow components to cool down if the vehicle has been running prior to inspection.

Symptoms

•Frequent blowing of fuses
•Inoperative electrical components (e.g., lights, radio, windows)
•Burning smell near fuse box or affected components
•Dashboard warning lights illuminated
•Intermittent electrical malfunctions (e.g., flickering lights)

Diagnostic Steps

1
Inspect the fuse box for signs of damage or corrosion.
2
Use an OBD-II scanner to check for any stored error codes related to electrical systems.
3
