Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a level surface and the ignition is off.
Disconnect the negative battery cable to prevent electrical shock.

2. Battery Inspection and Replacement

Inspect Battery Condition:
- Look for signs of corrosion on terminals. Clean with a wire brush and a mixture of baking soda and water if needed.
Test Battery Voltage:
- If battery voltage is below 12.4 volts, charge the battery or replace it if it fails to hold a charge.

3. Starter Motor Replacement

Remove Starter:
- Locate the starter motor (usually near the transmission).
- Disconnect the electrical connectors attached to the starter.
- Remove the mounting bolts using a socket set (typically 12mm or 14mm).
Install New Starter:
- Position the new starter motor in place and secure it with mounting bolts (torque to manufacturer specifications).
- Reconnect the electrical connectors ensuring a tight fit.

4. Checking and Replacing the Ignition Relay

Locate Ignition Relay:
- Find the relay in the fuse box (refer to the owner’s manual for location).
Replace Relay:
- Remove the faulty relay and insert a new one (ensure it matches the specifications).

5. Reconnect Battery and Test

Reconnect the negative battery terminal securely.
Start the vehicle to verify that the clicking noise has stopped and the engine starts smoothly.
