2. Carefully disconnect the negative (-) terminal first, followed by the positive (+) terminal.
3. Remove the old battery and replace it with a new one, ensuring it matches the specifications.
4. Reconnect the positive (+) terminal first, followed by the negative (-) terminal.
5. Secure the battery with the hold-down bracket.

3. Fuse Replacement (if necessary)

Sub-steps:
1. Locate the fuse box, typically found under the dashboard or in the engine compartment.
2. Identify the blown fuse using the diagram on the fuse box cover.
3. Remove the blown fuse with fuse pullers or pliers.
4. Insert a new fuse of the same amperage.
5. Close the fuse box and reconnect the battery.

4. Cleaning Electrical Connections

Sub-steps:
1. Disconnect battery terminals.
2. Use a wire brush and electrical contact cleaner to clean corroded terminals and connectors.
3. Reconnect cleaned connections ensuring they are tight and secure.

5. Wiring Repair (if necessary)

Sub-steps:
1. Identify damaged wires in the wiring harness.
2. Cut out damaged sections and strip the insulation from the ends.
