Inspect all of the battery cable's length for damage periodically, as well as check for cracked or burned insulation and corrosion because bad battery cable connections may make starting problems and reduce engine performance. Look at the cable-to-terminal connections found on each end of the cables to see whether they have any corrosions, cracks and loose wire strands. One is required to introduce a new battery cable whenever there are white, fluffy deposits under the insulation at its terminal connection point. Inspect for corrosion terminals on distortion, missing mounting bolts or nuts. Unfasten only the negative cable from the battery if we shall replace only positive one. Take off the cable altogether, making sure that it would be similar in length and diameter with the one that will be used instead of it. Use a wire brush to clean threads of rust and corrosion while applying a light layer of petroleum jelly onto them so that insertion could be easier next time without rusting and corroding taking place. Securely tighten mounting nut connecting cable to starter or ground connection by machine screw type binder head screw. Before reconnecting this new lead to the battery, make sure it will fit onto its terminals without stretching it out too much. First connect +cable then -cable.
