Fasten the Ground Wire

  1. 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.
  2. Drill a small hole into the metal that you intend to fasten the ground wire to.
  3. Use a punch to dimple and enlarge the hole until it is the same size as the screw.
  4. Scrape off a small circle of paint around the hole to make sure bare metal is exposed.
  5. Secure the wire with a #8 5/8-inch screw and flat washer.
