Solution

1. Preparation

Gather necessary tools and parts.
Tools Required: Multimeter, socket set, wrench set, wire brush or terminal cleaner.
Disconnect the negative terminal of the battery to ensure safety.

2. Battery Inspection

Clean battery terminals using a wire brush to remove any corrosion.
Tighten connections on the battery terminals to ensure a good electrical connection.
If the battery voltage is below 12.4 volts, charge or replace the battery.

3. Starter Relay and Fuse Check

Remove the starter relay from the fuse box.
Inspect the fuse related to the starter circuit for continuity.
If the relay is faulty, replace it with a new one.

4. Starter Testing

Reconnect the battery and use a multimeter to check voltage at the starter solenoid.
If there is no voltage, inspect wiring and connections leading to the starter.
If there is voltage but the starter does not engage, replace the starter motor.

5. Ground Connection Inspection

Inspect and clean the ground connections from the battery to the chassis and engine block.
Ensure all connections are tight and free from corrosion.
