Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Clean Battery Connections

Remove the positive (+) and negative (-) battery cables.
Clean the terminals with a wire brush to remove any corrosion.
Reconnect the battery terminals securely.

3. Test and Replace the Battery (if necessary)

Use a multimeter to check the battery voltage; if below 12.4 volts, replace the battery.
Remove the old battery by loosening the hold-down bracket.
Install the new battery by placing it in the tray and securing it with the bracket.

4. Check and Replace the Starter Motor (if necessary)

Remove any components obstructing access to the starter motor (e.g., air intake hoses).
Disconnect the electrical connections from the starter.
Remove the starter motor bolts using a socket set.
Install the new starter by reversing the removal steps, ensuring all connections are secure.
