Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery cable to prevent electrical shock or shorts.
Ensure the vehicle is in a safe, well-ventilated area.

2. Battery Inspection and Replacement

Inspect the battery: Check for physical damage, corrosion on terminals, or leakage.
Clean battery terminals: Use a wire brush to remove corrosion. Disconnect the positive terminal first followed by the negative.
Replace the battery if voltage is below 12.4 volts or if it shows signs of damage.
- Tools: Wrench or socket set, wire brush.

3. Starter Motor Replacement

Remove starter motor:
- Disconnect the electrical connectors and remove the mounting bolts.
- Carefully take out the starter motor from the engine compartment.
Install new starter motor:
- Position the new starter motor and secure it with mounting bolts to the specified torque (usually between 20-30 Nm).
- Reconnect electrical connectors to the starter motor.

4. Ignition Switch Inspection/Replacement

Access ignition switch: Remove any necessary panels to reach the ignition switch.
Test the ignition switch: Use a multimeter to check if the switch is functioning correctly.
Replace the ignition switch if it is faulty.
- Tools: Screwdrivers, multimeter.

5. Final Assembly

Reconnect the negative battery cable.
Ensure all connections are secure and replace any panels removed during the process.
