Solution

1. Preparation

Gather tools: multimeter, socket set, jumper cables, and safety gloves.
Disconnect the negative terminal of the battery to ensure safety while working.

2. Battery Inspection

Check Battery Condition
- Use a multimeter to measure the battery voltage. A healthy battery should read around 12.6 volts.
- If the voltage is below 12.4 volts, charge the battery or replace it if necessary.
Clean Battery Terminals
- Inspect the battery terminals for corrosion. If corrosion is present, clean the terminals with a mixture of baking soda and water.
- Ensure the battery terminals are tight and secure.

3. Jump-Start Procedure

Jump-Start the Vehicle
- Connect the positive (red) jumper cable to the positive terminal of the dead battery.
- Connect the other end of the positive cable to the positive terminal of a working battery.
- Connect the negative (black) cable to the negative terminal of the working battery.
- Connect the other end of the negative cable to a metal ground on the engine block of the dead vehicle.
- Attempt to start the vehicle.

4. Starter Motor Testing

Bypass the Ignition Switch
- Locate the starter motor and identify the terminals.
- Using a jumper wire, connect the battery positive terminal directly to the starter solenoid terminal.
- If the motor cranks, the starter is functional; if not, it may need replacement.

5. Final Checks

Inspect Fuses
- Locate the fuse box and check for any blown fuses related to the starting system.
- Replace any blown fuses with the appropriate amperage.
