Solution

1. Preparation

Gather tools and parts required for the repair.
Tools Required: Multimeter, socket set, torque wrench, battery terminal cleaner, jumper cables.
Safety Warnings: Disconnect the negative battery terminal before working on the electrical system.

2. Battery Inspection and Replacement

Sub-steps:
1. Inspect Battery Terminals:
  - Clean any corrosion from the battery terminals using a battery terminal cleaner.
  - Ensure the connections are tight and secure.
2. Test Battery Voltage:
  - Connect the multimeter to the battery terminals and check for voltage.
  - If the voltage is below 12.4 volts, proceed to replace the battery.
3. Replace Battery:
  - Remove the negative terminal first, then the positive terminal.
  - Remove the battery hold-down clamp and lift the battery out.
  - Install the new battery (positive terminal first, then negative).
  - Ensure the battery is secured by the hold-down clamp.

3. Starter and Relay Inspection

Sub-steps:
1. Check Starter Relay:
  - Locate the relay in the fuse box and remove it.
  - Swap with another relay of the same type to test functionality.
2. Inspect Starter Motor:
  - If clicking persists, check the connections on the starter motor.
  - If needed, remove the starter motor and bench test it with jumper cables to verify operation.
3. Replace Starter Motor (if needed):
  - If the starter fails the bench test, replace it by removing the electrical connections and mounting bolts.
