Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent any electrical short circuits.

2. Battery Inspection

Tools Required: Multimeter, wire brush, socket set
Clean any corrosion from the battery terminals using a wire brush.
Reconnect the terminals and check the voltage again. If the voltage is low, proceed to replace the battery.

3. Starter Motor Testing

Tools Required: Jumper cables, multimeter
Disconnect the starter motor's electrical connector.
Use jumper cables to connect the starter motor directly to the battery to see if it engages. If it does not, the starter motor is likely faulty and needs replacement.

4. Fuse and Ignition Switch Check

Tools Required: Fuse puller, multimeter
Inspect and replace any blown fuses related to the starting system.
Test the ignition switch operation by checking for continuity when the key is turned to the start position.

5. Ground Connection Inspection

Tools Required: Socket set, multimeter
Inspect and clean all ground connections to the engine and chassis. Ensure they are tight and free from corrosion.
