Solution

1. Preparation

Gather tools and parts needed.
Disconnect the battery by removing the negative terminal first to ensure safety.
Wear safety gloves and goggles.

2. Clean Battery Terminals

Use a wire brush to clean any corrosion from the battery terminals and cable connectors.
Reattach the battery cables tightly to the battery terminals.

3. Test and Replace the Battery (if needed)

If the battery voltage is below 12.4 volts, charge the battery using a battery charger.
If the battery cannot hold a charge, remove it using a socket set and replace it with a new battery of the same specifications.

4. Inspect and Replace the Starter Motor (if needed)

If jump-starting does not work, locate the starter motor (usually near the bottom of the engine).
Remove the bolts securing the starter motor using a socket set.
Disconnect the electrical connectors from the starter.
Install the new starter motor by reversing the removal process.
Ensure all connections are tight and secure before reattaching the battery.

5. Final Assembly

Reconnect the battery, starting with the positive terminal followed by the negative.
Start the vehicle to check if the issue is resolved.
