Solution

1. Preparation

Gather tools: multimeter, socket set, battery terminal cleaner, and a battery tester.
Ensure the vehicle is in "Park" and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection

Inspect Terminals:
- Clean any corrosion on battery terminals using terminal cleaner.
- Ensure connections are tight and secure.
Test Battery:
- Reconnect the battery and use a multimeter to check the voltage.
- If voltage is below 12.4 volts, proceed to replace the battery.

3. Fuse and Ignition Check

Replace Fuse:
- Locate the fuse box and identify the starter motor fuse.
- Remove the fuse and check for continuity. Replace if blown.
Ignition Switch:
- Remove the ignition switch cover and test the switch with a multimeter for continuity when turned to the start position.
- Replace the ignition switch if faulty.

4. Starter Motor Check

Inspect Wiring:
- Visually inspect wiring and connectors leading to the starter motor for damage or wear.
Test Starter Motor:
- Connect a jump lead directly to the starter motor from the battery to test its operation.
- If the starter does not engage, replace the starter motor.
