Every now and then run an eye along the entire length of a battery cable and look out for signs of damage, cracked or burnt insulation and corrosion of course due to loose connections there could be starting issues and decreased engine response. The soldered links between the cable and terminal should be examined for crack, loose strands of the wire and corrosion; White fluffy deposits seen on the outer cover indicates corrosion, and therefore the whole cable needs to be replaced. It is always safer to disconnect the negative terminal before disconnecting the cables and reconnect the same before connecting the positive terminal. Remove the Battery cables from the battery, follow the cables to their other ends and remove them from the
Starter Solenoid and Ground locations as well, take note of the path of the cables for the proper reconnection. If just replacing the cables, take the old cables so that the purchased ones match as the positive cables are normally red and bigger than the ground which is normally black and thin. Remove the insolent threads of the solenoid or ground connection using a wire brush to reduce or eradicate the rust and corrosion.After that one should cover them lightly with the battery terminal corrosion inhibitor or petroleum jelly of any kind in order to prevent similar problems from occurring in future. Screw or bolt this cable to the solenoid or the ground terminal securely tightening the mounting nut. When connecting a new cable, this should not be stretched in order to touch the battery post and connecting the positive cable then the negative one.
