Solution

1. Preparation

Tools Required: Wrench set, multimeter, battery load tester, socket set.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Battery Inspection and Replacement

Check Battery Voltage:
- Use a multimeter to measure the battery voltage.
- If below 12.4 volts, charge the battery or replace it if it cannot hold a charge.
Inspect and Clean Terminals:
- Remove the battery terminals (negative first, then positive).
- Clean any corrosion from the terminals and battery posts using a wire brush and a mixture of baking soda and water.
- Reconnect the terminals securely.

3. Starter Motor Check

Inspect Connections:
- Locate the starter motor and check all connections for tightness.
- Clean any corrosion from the starter terminals.
Test Starter Motor:
- If the battery is good, use a jumper wire to apply 12 volts directly to the starter motor to see if it engages.
- If the starter does not engage, it may need to be replaced.

4. Ignition Switch and Wiring Check

Test Ignition Switch:
- Use a multimeter to check the continuity of the ignition switch when turned to the start position.
- Replace the ignition switch if it does not pass the continuity test.

5. Reassemble and Finalize

Reconnect the negative battery terminal.
Ensure all tools are removed from the engine compartment and close the hood securely.
