Remove Battery:
- Unscrew and remove any securing brackets. Carefully lift out the battery.
Install New Battery:
- Place the new battery in the same position, ensuring it sits securely.
Reconnect Battery Cables:
- Connect the positive terminal first, followed by the negative terminal. Ensure connections are tight.

3. Fuse Replacement (if blown)

Locate Fuse Box:
- Refer to the owner’s manual for the exact location of the fuse box.
Identify Blown Fuse:
- Use the fuse diagram to locate the specific fuse; pull it out and inspect it.
Replace Fuse:
- Insert a new fuse of the same amperage rating into the correct slot.

4. Ground Connection Repair

Locate Ground Points:
- Identify all ground points related to the electrical circuits in question.
Clean Ground Connections:
- Remove ground connections, clean contact surfaces with a wire brush to remove corrosion, and reattach securely.
Test for Continuity:
- Use a multimeter to ensure continuity from the ground point to the battery's negative terminal.
