Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.
Disconnect the negative battery terminal to ensure safety.

2. Battery Inspection and Replacement

Inspect Battery Terminals
- Clean any corrosion from battery terminals using a wire brush.
- Tighten any loose connections securely.
Test and Replace Battery (if necessary)
- If the battery voltage is low, charge the battery fully or replace if it's unable to hold charge.
- Use a multimeter to verify the voltage after charging.
- Install the new battery and connect terminals (positive first, then negative).

3. Starter Motor Inspection and Replacement

Check Starter Connections
- Inspect the wiring harness connected to the starter for any signs of damage or loose connections.
- Tighten any loose connections or replace damaged wiring.
Test Starter Motor
- If the battery is good and connections are secure, test the starter motor by applying power directly from the battery.
- If the starter does not engage, it may need replacement.
Replace Starter Motor (if necessary)
- Remove the starter motor by disconnecting the electrical connections and unbolting it from its mount.
- Install the new starter motor and reconnect electrical connections securely.
