Solution

1. Preparation

Gather tools and parts: multimeter, socket set, jumper cables, battery terminal cleaner, and a replacement battery if necessary.
Ensure the vehicle is parked on a flat surface and the engine is off.

2. Battery Inspection and Cleaning

Sub-step 1: Disconnect the negative (-) battery terminal first, then the positive (+) terminal.
Sub-step 2: Clean any corrosion on the terminals using a battery terminal cleaner and a wire brush.
Sub-step 3: Reconnect the positive (+) terminal first, followed by the negative (-) terminal.

3. Battery Testing

Sub-step 1: Use a multimeter to check the battery voltage; replace the battery if voltage is below 12.4 volts.
Sub-step 2: If the battery is low, jump-start the vehicle or replace it with a new one.
Sub-step 3: If jump-starting works, test the battery's charging system while the engine is running.

4. Starter Motor Inspection

Sub-step 1: Remove the starter motor from its mounting (usually requires a socket set).
Sub-step 2: Inspect the starter motor for wear or damage and test it with a multimeter.
Sub-step 3: Replace the starter motor if it does not pass the test.
