2. Battery Inspection and Replacement

Sub-steps:
1. Remove the battery terminals, starting with the negative terminal.
2. Clean any corrosion from the terminals and battery posts using a wire brush.
3. Test the battery voltage again; if below 12.4 volts, charge or replace the battery as needed.
Tools Required:
- Multimeter
- Wire brush
Safety Warnings:
- Wear gloves and safety glasses when handling the battery.

3. Starter Motor Testing and Replacement

Sub-steps:
1. Reconnect the battery terminals to test the starter motor.
2. If the clicking persists, remove the starter motor (usually involves disconnecting wiring and removing mounting bolts).
3. Test the starter motor by applying direct battery voltage to it; if it does not engage, replace the starter motor.
4. Install the new starter motor in reverse order of removal, ensuring proper torque on mounting bolts.
