Solution

1. Preparation

Gather the necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Clean Battery Connections

Remove the positive and negative battery cables using a socket set.
Clean the terminals and cable ends with a wire brush to remove corrosion.
Reattach the cables, ensuring they are tight and secure.

3. Test or Replace the Battery

If the battery voltage is below 12.4 volts, charge the battery using a battery charger.
If the battery fails to hold a charge or is more than 3-5 years old, replace it with a new one of the same specifications.
Reconnect the battery terminals after replacement.

4. Test the Starter Motor

Locate the starter motor beneath the vehicle.
Use a multimeter to check for voltage at the starter solenoid when the ignition is turned on.
If no voltage is detected, the issue may lie with the ignition switch or wiring.
If voltage is present but the starter does not engage, replace the starter motor.

5. Inspect the Ignition Switch

Remove the steering column cover to access the ignition switch.
Inspect the ignition switch for any signs of damage or wear.
If faulty, replace the ignition switch according to the manufacturer's specifications.
