2. Inspect and Clean Battery Terminals

Remove the battery terminals using a socket wrench.
Clean the terminals and battery posts with a wire brush.
Reconnect the terminals securely and ensure there is no corrosion.

3. Replace Blown Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Use a fuse puller to remove any blown fuses.
Replace them with the correct amperage fuses as per the owner's manual.

4. Repair or Replace Damaged Wiring

Visually inspect wiring harnesses for any frayed wires or exposed conductors.
Repair minor damage with electrical tape or heat-shrink tubing.
Replace severely damaged wiring segments with new wire of the same gauge, ensuring proper connections.

5. Test Ground Connections

Locate ground points, usually attached to the chassis.
Use a multimeter to check for continuity between the ground point and the negative battery terminal.
Clean or replace any poor connections.
