Solution

1. Preparation

Tools Required: Wrench set, multimeter, jumper cables, socket set.
Disconnect the negative battery terminal to prevent electrical shocks.

2. Battery Inspection

Sub-steps:
1. Inspect the battery for any signs of physical damage or swelling.
2. Clean any corrosion from the battery terminals using a wire brush and a mixture of baking soda and water.
3. Tighten the battery connections to ensure a solid contact.

3. Starter Motor Test

Sub-steps:
1. Locate the starter motor, typically found near the transmission.
2. Use a jumper wire to connect the battery positive terminal directly to the starter motor terminal.
3. If the starter engages and the engine turns over, the starter is likely faulty and needs replacement.

4. Fuse and Ignition Switch Check
