Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal.

2. Battery Inspection and Replacement

Inspect Battery Terminals
- Clean any corrosion with a wire brush.
- Tighten any loose connections.
Test Battery Voltage
- If the voltage is below 12.4 volts, charge the battery or replace it if it fails the load test.
- If replacing, remove the battery by unbolting it from the tray and disconnecting the positive terminal first, then the negative.
Install New Battery
- Place the new battery in the tray.
- Connect the positive terminal first, followed by the negative terminal.
- Ensure the terminals are securely tightened.

3. Starter Motor Inspection

Check Starter Relay and Fuse
- Locate the fuse box and check the starter fuse for continuity. Replace if blown.
- Swap the starter relay with a similar relay in the fuse box to test functionality.
Inspect Starter Motor Connections
- If the battery is good and the starter relay is functional, check the starter motor connections.
- Clean and tighten connections as needed.

4. Final Assembly

Reconnect the negative battery terminal.
Ensure all tools are removed from the engine bay.
