Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is in a safe location with the ignition off.
• Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

• Sub-step 1: Inspect the battery terminals for corrosion. Clean with a wire brush if necessary.
• Sub-step 2: If the battery voltage is below 12.4 volts, charge the battery using a battery charger.
• Sub-step 3: If the battery fails to hold a charge or is older than 3-5 years, replace it with a new one.
  • Tools Required: Battery terminal cleaner, battery charger, or wrench for battery terminal removal.
  • Safety Warnings: Wear gloves and safety goggles while handling the battery.

3. Starter and Relay Replacement

• Sub-step 1: If the clicking persists after battery service, locate the starter relay in the fuse box and swap it with a known working relay.
• Sub-step 2: If the problem remains, remove the starter from the engine (unbolt and disconnect wiring).
• Sub-step 3: Test the starter with a bench test or replace it if it is defective.
  • Tools Required: Socket set, screwdriver, multimeter.
  • Safety Warnings: Disconnect the negative battery terminal before removing the starter.
