Solution

1. Preparation

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

2. Battery Inspection and Replacement

Tools Required: Wrench set, multimeter
Sub-steps:
1. Remove the battery terminals (negative first, then positive).
2. Clean the terminals and connectors using a wire brush.
3. Test the battery with a multimeter; if below 12.4 volts, replace the battery.
4. If replacing, install the new battery (positive first, then negative).

3. Starter Motor Inspection

Tools Required: Socket set, screwdriver
Sub-steps:
1. Locate the starter motor (typically near the engine under the vehicle).
2. Disconnect the electrical connectors and remove the mounting bolts.
3. Inspect the starter gear for damage or wear.
4. Test the starter motor operation using a bench test (if necessary).
5. Replace the starter motor if it is faulty.

4. Check Starter Relay and Wiring

Tools Required: Multimeter
Sub-steps:
1. Locate the starter relay in the fuse box.
2. Test the relay for continuity with a multimeter.
3. Inspect the wiring harness for frays or damage.
4. Replace the relay if it is found to be defective.
