Solution

1. Preparation

Gather tools and parts before starting the repair.
Tools required: socket set, multimeter, jumper wire, wrench set, safety glasses, gloves.
Ensure the vehicle is in "Park" or "Neutral" with the parking brake engaged.

2. Battery Inspection and Replacement

Disconnect Battery
- Use a wrench to disconnect the negative (-) terminal first, then the positive (+) terminal.
Inspect Battery Condition
- Check for physical damage, leaks, or corrosion on the terminals.
- Clean the terminals with a wire brush if necessary.
Test Battery Voltage
- Use a multimeter to measure the voltage; if below 12.4 volts, charge or replace the battery.
Reconnect Battery
- Connect the positive (+) terminal first, then the negative (-) terminal.

3. Starter Motor Inspection

Locate Starter Motor
- Identify and access the starter motor under the vehicle.
Check Connections
- Ensure the electrical connections to the starter are secure and free of corrosion.
Test Starter Functionality
- Use a jumper wire to connect the positive terminal of the battery directly to the starter. If the starter engages, it may need replacement.
Remove and Replace Starter if Necessary
- Disconnect wires and remove bolts securing the starter.
- Install the new starter motor by reversing the removal process.

4. Final Assembly and Testing

Reconnect all Components
- Ensure all connections are secured, including battery terminals and starter wiring.
Test Start the Engine
- Attempt to start the vehicle and monitor for any abnormal sounds or issues.
