Fasten the Ground Wire
- The braided wire on the vehicle battery cable is the grounding strap. To ensure proper cable shielding, fasten the ground strap to the vehicle sheet metal.
- Drill a small hole into the metal that you intend to fasten the ground wire to.
- Use a punch to dimple and enlarge the hole until it is the same size as the screw.
- Scrape off a small circle of paint around the hole to make sure bare metal is exposed.
- Secure the wire with a #8 5/8-inch screw and flat washer.
