Solution

1. Preparation

Tools Required: Safety gloves, multimeter, socket set, wrench set.
Disconnect the negative battery cable to ensure safety.

2. Battery Inspection and Testing

Sub-steps:
1. Remove the battery from the vehicle if necessary.
2. Clean battery terminals with a wire brush to remove corrosion.
3. Use a multimeter to test the battery voltage; it should read at least 12.6 volts for a fully charged battery.
4. If the voltage is below 12.4 volts, charge the battery using a compatible charger.

3. Starter Motor Testing

Sub-steps:
1. Reconnect the battery and locate the starter motor.
2. Use a multimeter to check the voltage at the starter terminal while someone turns the ignition. It should read battery voltage.
3. If no voltage is present, the ignition switch or wiring may be faulty.
4. If voltage is present, proceed to test the starter by using a jumper wire to bypass the ignition circuit.

4. Wiring and Connection Inspection

Sub-steps:
1. Visually inspect all wiring from the battery to the starter for signs of damage or loose connections.
2. Tighten any loose connections and repair damaged wiring as needed.
3. Ensure all ground connections are secure and free of corrosion.

5. Reassembly

Sub-steps:
1. Reinstall any removed components and secure them properly.
2. Reconnect the negative battery cable.
3. Close the hood and prepare for testing.
