Solution

1. Preparation

Gather tools including a multimeter, socket set, and battery terminal cleaner.
Ensure the vehicle is in park (or neutral for manual) with the parking brake engaged.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Battery Replacement (if faulty)

Remove the Old Battery:
- Disconnect the negative terminal first, followed by the positive terminal.
- Remove any securing brackets and lift the battery out of the tray.
Install New Battery:
- Place the new battery in the tray and secure it with the brackets.
- Connect the positive terminal first, followed by the negative terminal.
- Ensure all connections are tight and free of corrosion.

3. Starter Motor Replacement (if necessary)

Remove Starter Motor:
- Disconnect the negative battery terminal (if not already done).
- Locate the starter motor, typically positioned near the transmission.
- Remove electrical connections from the starter (note the orientation).
- Unbolt the starter motor using the appropriate socket size, usually 12mm or 14mm.
- Carefully remove the starter from its position.
Install New Starter Motor:
- Position the new starter motor in place and secure it with bolts to the transmission.
- Reattach the electrical connections in the same orientation as removed.
- Ensure all connections are secure.

4. Test and Reassemble

Reconnect Battery:
- Reconnect the negative terminal.
- Ensure all tools are removed from the engine bay.
Start the Vehicle:
- Turn the ignition key to start the vehicle.
- If the vehicle starts, monitor for any unusual noises or dashboard lights.
