Solution

1. Preparation

Gather tools and safety equipment: gloves, safety glasses, multimeter, and socket set.
Ensure the vehicle is in park or neutral and the parking brake is engaged.

2. Battery Inspection

Disconnect the Battery:
- Use a socket set to remove the negative terminal first, then the positive terminal to prevent short circuits.
Clean the Battery Terminals:
- Remove any corrosion using a wire brush or terminal cleaner, then reconnect the terminals securely.

3. Battery Testing

Test Battery Voltage:
- Connect the multimeter to the battery terminals.
- A healthy battery should read around 12.6 volts. If below 12.4 volts, the battery may be weak.
Jump Start the Vehicle:
- If the voltage is low, use jumper cables to connect to a working vehicle or use a battery charger.

4. Starter Motor Inspection

Locate the Starter Motor:
- It is typically located near the transmission.
Test the Starter:
- Use jumper cables to connect the positive terminal of the battery directly to the starter's positive terminal.
- Ensure the negative is grounded. If the starter engages and the engine cranks, the starter is functional.

5. Reassemble and Test

Reconnect Battery:
- Reconnect the positive terminal first, then the negative terminal.
Attempt to Start the Engine:
- Turn the key to start the engine and observe for any changes.
