Solution

1. Preparation

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

2. Battery Replacement (if battery is faulty)

Remove the positive battery terminal followed by the negative terminal.
Unscrew and remove the battery hold-down clamp.
Carefully lift the battery out of the engine bay.
Install the new battery by placing it in the tray and securing it with the hold-down clamp.
Reconnect the negative terminal first, followed by the positive terminal.

3. Starter Motor Replacement (if starter is faulty)

Locate the starter motor, typically found near the transmission.
Disconnect the battery if not already done.
Remove the electrical connections to the starter (usually a main power cable and a smaller signal wire).
Unscrew the mounting bolts securing the starter to the engine or transmission.
Carefully remove the starter motor from its location.
Install the new starter motor by reversing the removal steps, ensuring all connections are secure.

4. Ignition Switch Testing (if switch is faulty)

Locate the ignition switch, typically found behind the ignition cylinder.
Remove any panels to access the ignition switch.
Disconnect the wiring harness from the ignition switch.
Use a multimeter to test continuity through the switch. Replace it if it shows no continuity when in the "start" position.
Reassemble the panels and reconnect the battery.
