Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is in a well-ventilated area with the engine off.
Disconnect the battery to prevent electrical shock.

2. Battery Check and Replacement

Inspect and Clean Battery Terminals
- Disconnect negative (-) and positive (+) battery cables.
- Clean terminals with a wire brush and a solution of baking soda and water.
- Reconnect battery cables securely.
Test Battery
- Use a multimeter to confirm battery voltage; replace the battery if voltage is below 12.4 volts.
- If replacement is needed, remove the old battery and install a new one, ensuring correct terminal connections.

3. Starter Motor Inspection and Replacement

Inspect Starter Connections
- Locate the starter motor; check for loose or corroded connections.
- Tighten any loose connections and clean corrosion as needed.
Starter Motor Removal
- If the starter is suspected to be faulty, remove it:
  - Disconnect the battery again for safety.
  - Unbolt the starter motor from its mounting (usually requires a socket set).
  - Remove electrical connections from the starter.
Install New Starter Motor
- Position the new starter motor in place.
- Reconnect electrical connections and secure the starter with bolts to the manufacturer’s torque specifications.

4. Final Checks
