Solution

1. Preparation

Gather tools and ensure safety equipment is worn (gloves, safety glasses).
Disconnect the negative battery cable to prevent any electrical short.

2. Battery Inspection and Replacement

Inspect Battery Terminals
- Remove any corrosion using a wire brush or battery terminal cleaner.
- Tighten any loose connections to ensure a good electrical contact.
Test Battery Health
- If the battery voltage is below 12.4 volts, charge the battery using a battery charger.
- If the battery does not hold a charge or is older than 3-5 years, consider replacing it.

3. Starter Motor and Relay Inspection

Check Starter Relay
- Locate the starter relay in the fuse box and swap it with a similar relay.
- Attempt to start the vehicle again.
Inspect Starter Motor
- If the clicking persists, locate the starter motor on the engine.
- Check the connections to the starter for tightness and corrosion.
- Test the starter motor by applying direct battery voltage to the solenoid terminal (use caution).

4. Replace Parts if Necessary

Replacing the Battery or Starter
- If the battery is faulty, remove it and install a new one, ensuring proper connections.
- If the starter motor is defective, remove the starter by:
  - Disconnecting electrical connections.
  - Removing mounting bolts (typically 2-3 bolts).
  - Installing the new starter in reverse order, ensuring proper torque on bolts (typically 15-25 ft-lb).
