that the cable cannot contact the terminal. When
four 12 volt batteries are involved, two negative
connection must be disconnected.
3. Remove the positive connection.
4. Clean all disconnected connection and battery
terminals.
5. Use a fine grade of sandpaper to clean the
terminals and the cable clamps. Clean the items
