Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the battery by removing the negative terminal.

2. Battery Inspection

Clean Terminals: Use a wire brush to clean the battery terminals and cable ends.
Reconnect Battery: Reconnect the battery terminals securely and check for tightness.

3. Jump Start Procedure

Connect Jumper Cables: Attach jumper cables to the dead battery and a charged battery following the correct sequence (positive to positive, negative to a ground on the dead vehicle).
Attempt to Start: Try starting the vehicle. If it starts, the battery may need replacement.

4. Starter Motor Test

Locate Starter: Access the starter motor, typically located near the transmission.
Direct Power Test: Using a jumper wire, connect the starter solenoid's terminal to the battery positive terminal. If it engages, the starter is functional.
Remove Starter: If necessary, remove the starter by unbolting it and disconnecting the electrical connections.

5. Replace/Repair Components

Replace Battery: If the battery is below 12.4 volts or fails to hold a charge, replace it with a new, compatible battery.
Replace Starter: If the starter does not engage during the power test, replace it with a new starter.
Inspect Wiring: Ensure all wiring and connections are intact and free from damage.
