Ensure the vehicle is in a safe location with adequate lighting.

2. Battery Inspection

Sub-steps:
1. Remove the battery terminals, starting with the negative terminal and then the positive.
2. Clean any corrosion from the terminals and battery posts using a wire brush.
3. Reconnect the battery terminals securely, first the positive then the negative.

Tools Required:

Wire brush
Wrench set

3. Fuse Replacement

Sub-steps:
1. Locate the fuse box, usually found under the dashboard or in the engine compartment.
2. Remove the ignition fuse with a fuse puller or pliers.
3. Inspect the fuse for any visible damage; replace it with a new one of the same amperage if needed.

Tools Required:

Fuse puller or pliers

4. Ignition Switch Testing

Sub-steps:
1. Locate the ignition switch, typically found on the steering column.
2. Disconnect the electrical connector from the ignition switch.
3. Use a multimeter to check for voltage at the connector while turning the key to the "on" position.
4. If no voltage is present, replace the ignition switch.

Tools Required:

Multimeter
Screwdriver set

5. Starter Relay Check
