Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent any electrical shorts.
Ensure the vehicle is on a flat surface and securely supported.

2. Inspect and Clean Battery Connections

Remove the battery terminals (negative first, then positive).
Clean the terminals and cable ends with a wire brush and a solution of baking soda and water to remove corrosion.
Reconnect the terminals, ensuring they are tight and secure.

3. Test and Replace Battery (if necessary)

If the battery voltage is below 12.4V and does not hold a charge, remove the battery.
Replace with a new battery of the same specification.
Reconnect the battery terminals, ensuring the positive is connected first.

4. Inspect and Replace Alternator (if necessary)

If the alternator does not charge the battery above 13.7V when the engine is running, remove the drive belt.
Disconnect the alternator wiring harness and remove the mounting bolts.
Replace with a new alternator and reassemble in reverse order, ensuring all electrical connections are secure.

5. Final Checks

Reconnect the negative battery terminal.
Start the engine and check the voltage at the battery again to confirm proper charging.
