Solution

1. Preparation

Gather tools and parts needed for repair.
Disconnect the negative battery terminal to prevent electrical shock.

2. Clean Battery Terminals

Remove the battery terminals from the battery.
Clean the terminals and battery posts using a wire brush and a mixture of baking soda and water.
Reattach the terminals securely and ensure they are tight.

3. Inspect and Replace Fuses

Locate the fuse box and remove the cover.
Identify any blown fuses related to the dashboard or electrical components.
Replace any blown fuses with new ones of the same amperage.

4. Check and Replace Wiring

Inspect the wiring harness for any visible damage, fraying, or loose connections.
Repair or replace any damaged wiring using appropriate gauge wire and connectors.
Ensure all connectors are seated properly.

5. Test Battery and Alternator

Reconnect the negative battery terminal.
Start the engine and measure the battery voltage at idle with a multimeter; ensure it reads between 13.5 to 14.5 volts.
If the voltage is low, consider replacing the alternator.
