Solution

1. Preparation

Tools Required: Socket set, multimeter, jumper cables, wire brush, safety gloves, and eye protection.
Ensure the vehicle is in "Park" or "Neutral" and the parking brake is engaged.

2. Battery Inspection

Step 1: Turn off all electrical accessories.
Step 2: Remove the negative battery terminal first, followed by the positive terminal to prevent short circuits.
Step 3: Inspect the battery terminals for corrosion; clean any corrosion with a wire brush.
Step 4: Reconnect the positive terminal first, then the negative terminal securely.

3. Jump-Start Procedure

Step 1: Connect jumper cables to the dead battery, ensuring correct polarity (red to positive, black to negative).
Step 2: Connect the other end of the cables to a working vehicle or a jump starter.
Step 3: Attempt to start the vehicle. If it starts, allow it to run for at least 15-20 minutes to charge the battery.

4. Starter Motor Testing

Step 1: Locate the starter motor under the vehicle, usually near the transmission.
Step 2: Disconnect the wiring harness from the starter.
Step 3: Use jumper cables to apply power directly to the starter motor. If it engages and the engine cranks, the starter is likely good.
Step 4: If the starter does not engage, it may need replacement.

5. Fuses and Relays Check

Step 1: Access the fuse box (usually located under the dashboard or in the engine compartment).
Step 2: Inspect fuses related to the starting system and replace any that are blown.
Step 3: Check the starter relay; replace it if it is defective.
