2. Battery Inspection and Replacement

Inspect Battery:
- Remove any corrosion from battery terminals using a wire brush.
- Tighten any loose connections.
Replace Battery (if necessary):
- Disconnect the positive terminal first, followed by the negative terminal.
- Remove the battery clamps and take out the old battery.
- Install the new battery, connecting the positive terminal first, then the negative terminal.

3. Starter Motor Testing and Replacement

Test Starter Motor:
- Locate the starter motor and check the wiring for any disconnections or damage.
- Use a multimeter to check voltage at the starter while attempting to start the engine.
Replace Starter Motor (if faulty):
- Disconnect electrical connectors and bolts securing the starter.
- Remove the old starter and install the new one, ensuring all connections are secure.

4. Ignition Switch Inspection and Replacement

Inspect Ignition Switch:
- Remove the steering column cover to access the ignition switch.
- Use a multimeter to check the switch for continuity when the key is turned.
Replace Ignition Switch (if faulty):
- Disconnect the wiring harness from the ignition switch.
- Remove the screws securing the switch and replace it with a new unit.

5. Fuse Check and Replacement

Inspect Fuses:
- Locate the fuse box and check for any blown fuses related to the ignition system.
