2. Check the wire terminals for cracks, signs of copper strands falling out, and signs of corrosion. The presence of white powdery deposits accumulated under the insulation layer near the terminal lugs indicates the development of corrosion and the need to replace the wire. Check battery terminals and wire end clamps for signs of deformation, loose bolts, and corrosion.
3. When replacing wires, follow the instructions given in Section 8. Remember to disconnect the negative wire even if only the positive one is to be replaced. Try to remember the routes for laying both wires in order to follow them when installing new ones.
4. Take the wire to be replaced with you to the store as a sample. An extremely important factor is that the design of the wire clamps matches the shape of the connection terminals on the vehicle.
Note: As a rule, the wires are easily distinguished from each other by the color of the insulation, always black on the negative and red on the positive. In addition, the positive wire usually has a larger cross section.
5. Before connecting a new wire to the battery terminal, make sure that it reaches freely without excessive tension. Thoroughly clean the battery terminals, then lightly grease them with acid-free Vaseline.
