Solution

1. Preparation

Gather required tools and parts.
Disconnect the negative terminal of the battery to ensure safety.

2. Inspect Battery

Check battery terminals for corrosion. Clean if necessary using a wire brush and a mixture of baking soda and water.
Ensure the terminals are tightly connected. If they are loose, tighten them securely.

3. Test Battery and Alternator

Reconnect the battery and use a multimeter to measure the battery voltage. It should read between 12.4 to 12.7 volts with the engine off.
Start the engine and measure the voltage again. It should read between 13.7 to 14.7 volts to indicate the alternator is charging correctly.

4. Inspect Ground Connections

Locate and remove the ground connection point (usually near the battery or engine block).
Clean the area and the terminal to ensure a good connection.
Reattach the ground connection securely.

5. Check Wiring Harness

Inspect the wiring harness leading to the dashboard for any signs of fraying, wear, or disconnection.
Repair any damaged wires using electrical tape or replace any damaged sections of the harness.

6. Reconnect Battery

Reconnect the negative battery terminal securely.
Ensure all connections are tight and secure.
