Solution

1. Battery Inspection

Tools Required: Wrench set, multimeter
Inspect the battery terminals and clean any corrosion. Tighten loose connections.
Measure the voltage with a multimeter; if it’s below 12.4 volts, consider replacing the battery.

2. Alternator Test

Tools Required: Multimeter
Start the engine and measure the voltage at the battery terminals. It should read between 13.7 to 14.7 volts.
If the voltage is low, replace the alternator.

3. Fuse Inspection

Tools Required: Fuse puller or pliers
Locate the fuse box and identify fuses related to the dashboard and electrical systems.
Replace any blown fuses with the correct amperage rating.

4. Wiring Inspection

Tools Required: Visual inspection tools, possibly a multimeter
Examine the wiring harness for frayed wires or signs of short circuits.
Repair or replace damaged wiring as necessary.

5. Final Assembly

Reconnect all components securely and ensure no tools are left in the engine bay.
Close the fuse box and battery terminals properly.
