Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety while working on electrical components.

2. Battery Inspection and Replacement

Inspect the Battery:
- Remove the battery terminals (negative first, then positive).
- Clean any corrosion with a wire brush and a mixture of baking soda and water.
Test or Replace the Battery:
- If the battery voltage is low, charge the battery or replace it if it's more than 4-5 years old.

3. Starter Relay and Fuse Check

Check Starter Relay:
- Locate the starter relay in the fuse box.
- Swap it with a similar relay to test functionality.
Inspect Fuses:
- Locate the fuse box and inspect the fuses related to the starting system.
- Replace any blown fuses with the correct amperage rating.

4. Starter Motor Inspection

Remove Starter Motor:
- Disconnect the negative battery terminal.
- Remove the starter motor wiring (positive and ground connections).
- Unbolt and remove the starter motor from its mounting.
Test Starter Motor:
- Using a multimeter, check for continuity and proper operation.
- If faulty, replace the starter motor with a new one.

5. Reassembly

Reinstall the starter motor and reconnect all wiring.
Reattach the battery terminals (positive first, then negative).
