Solution

1. Preparation

Gather tools and materials: multimeter, load tester, wrench set, battery terminal cleaner, safety goggles, gloves.
Ensure the vehicle is in a safe location with the parking brake engaged.

2. Battery Inspection

Check Battery Voltage:
- Connect the multimeter to the battery terminals (red to positive, black to negative).
- A voltage reading below 12.4 volts indicates a weak battery.
Clean Terminals:
- Use a battery terminal cleaner to remove corrosion from the terminals.
- Tighten the connections with a wrench to ensure a good contact.

3. Load Test the Battery

Load Test:
- Disconnect the battery from the vehicle.
- Connect the load tester to the battery following the manufacturer's instructions.
- If the battery fails the load test, replace it with a new one.

4. Starter and Ignition Check

Inspect Starter Connections:
- Locate the starter motor and check the connections for tightness and corrosion.
- Clean the terminals if necessary and reconnect.
Test Ignition Switch:
- Use a multimeter to test for continuity at the ignition switch.
- Replace the ignition switch if it fails to show continuity.

5. Final Checks

Reconnect the battery and attempt to start the vehicle.
If the issue persists, further diagnostics may be needed for the starter or wiring.
