2. Addressing Faulty Components

Replace Fuses:
- Identify blown fuses from the inspection.
- Remove the faulty fuse using a fuse puller.
- Replace with a new fuse of the same amperage as specified in the owner's manual.
Repair Wiring Issues:
- If damaged wiring is found, cut out the damaged section.
- Strip the ends of the wire and splice in new wire using solder or crimp connectors.
- Insulate with electrical tape or heat shrink tubing.

3. Battery and Alternator Maintenance

Battery Replacement:
- Remove the negative terminal first, followed by the positive terminal from the battery.
- Remove any securing brackets and lift out the old battery.
- Position the new battery in place, securing it with brackets.
- Connect the positive terminal first, then the negative terminal.
Alternator Replacement (if necessary):
- Disconnect the battery.
- Remove the serpentine belt from the alternator.
