Solution

1. Preparation

Gather tools: multimeter, socket set, wire brush, OBD-II scanner.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent electrical shock.

2. Inspect Battery Connections

Use the socket set to remove the battery terminals.
Clean the battery terminals and connectors with a wire brush to remove corrosion.
Reconnect the terminals, ensuring they are tight and secure.

3. Check Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the fuses related to the lighting circuit using the fuse puller.
Inspect each fuse for continuity; replace any blown fuses with the same amperage rating.

4. Test Alternator Output

Reconnect the battery and start the vehicle.
Use the multimeter to measure the voltage at the battery terminals; it should read between 13.7V to 14.7V while the engine is running.
If the voltage is below this range, the alternator may need to be replaced.

5. Check Wiring Harness

Visually inspect the wiring harness for any signs of fraying or damage.
Repair or replace any damaged wires using appropriate gauge wire and connectors.
