Ensure you have enough workspace and light for thorough inspection.

2. Battery Inspection and Replacement

Sub-steps:
1. Remove the battery cover (if applicable).
2. Disconnect the positive terminal followed by the negative terminal.
3. Inspect the battery for swelling or leakage; if damaged, replace with a new battery (make sure it meets manufacturer specifications).
4. Clean the terminals and cable connectors with a wire brush and apply anti-corrosion spray.
5. Reconnect the terminals, starting with the positive terminal.

3. Fuse Replacement

Sub-steps:
1. Locate the fuse box (refer to the owner’s manual for exact location).
2. Identify and remove any blown fuses using a fuse puller.
3. Replace blown fuses with new ones of the same amperage rating.
4. Close the fuse box securely after replacement.

4. Wiring Inspection

Sub-steps:
1. Visually inspect wiring harnesses for any frayed wires or broken connectors.
2. Repair or replace damaged wires using automotive-grade wire and connectors.
3. Ensure all connectors are seated properly and locked in place.

5. Ground Connections Check

Sub-steps:
1. Identify all ground points in the engine bay and under the dashboard.
2. Clean each grounding point with sandpaper to remove corrosion.
3. Tighten all ground connections to ensure a secure contact.
