Solution

1. Preparation

Tools Required: Multimeter, socket set, battery terminal cleaner, jumper cables.
Disconnect the negative battery cable to ensure safety.

2. Battery Inspection and Replacement

Check Battery Condition
- Use a multimeter to measure the battery voltage.
- If voltage is below 12.4 volts, proceed to charge or replace the battery.
Clean Terminals
- If corrosion is present, clean the battery terminals and cable connectors using a terminal cleaner or a mixture of baking soda and water.
- Reattach the cables securely.
Replace Battery (if necessary)
- If the battery is faulty, remove it from the vehicle using a socket set.
- Install the new battery, ensuring that the positive (+) and negative (-) terminals are correctly connected.

3. Starter System Inspection

Test Starter Relay
- Locate the starter relay (consult the owner’s manual for the exact location).
- Swap with a similar relay in the fuse box to check for functionality.
Inspect Starter Motor
- If the relay is functional, access the starter motor.
- Check connections for tightness and any visible damage.
- If necessary, replace the starter motor by removing it with a socket set and installing a new one.

4. Final Assembly

Reconnect the negative battery cable.
Ensure all components are secured and there are no loose wires.
