Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative terminal of the battery to prevent electrical shock and short circuits.

2. Clean Battery Terminals

Remove the battery terminals (negative first, then positive).
Clean any corrosion from the terminals and battery posts using a wire brush.
Reattach the terminals securely.

3. Test and Replace Alternator (if necessary)

Reconnect the battery terminals.
Start the engine and measure the voltage at the battery with a multimeter. It should read between 13.7V and 14.7V.
If the voltage is low, remove the alternator:
- Disconnect the wiring harness and the negative battery terminal.
- Unbolt the alternator from its mounting using a socket set.
- Replace with a new or refurbished alternator, ensuring proper alignment.
- Reconnect all wiring and the negative battery terminal.

4. Inspect and Repair Wiring

If wiring damage is found, replace or repair damaged wires. Use electrical tape or heat-shrink tubing to insulate splices.
Ensure all connectors are firmly attached and free from corrosion.

5. Replace Blown Fuses

Locate the fuse box and identify any blown fuses related to the dashboard and lighting circuits.
Replace them with new fuses of the same amperage rating.
