After a certain period, examine all of the battery cables from end to end for signs of damage, cracked or burnt insulation or corrosion. Poor battery cable connections may result in starting difficulties as well as reduce engine performances. Check the cable-to-terminal connections at the end of the wires for splits on it, frayed wire ends and corrosion. Seeing white fluffy substance beneath the insulation on the cable terminal connector implies corrosion has taken place in these areas and therefore cable ought to be replaced. The terminals should also be inspected for defects like deformation, no mounting bolts and instead corrosion. Never forget to remove negative lines first while loosening often when you are separating such cables this could cause crashing auxilary bar with your tool when you're trying loosening them because it is possible that you might mistakenly short circuit your battery with a tool used to loosen up the clamps if it is not done so properly always separate lines through removing minus one before positive one even though they will be replacing only a plus line.Disconnect old wires from batteries then find each one from which they are connected and release them off from solenoid starting system and ground part just opposite each other. Observe how every line is laid out before connecting them back properly. Always carry along both old cables if either ones want replacement.The identification of these cables cannot be difficult.Cleaning rust or corrosion should be done by use of brush that has wire threads; apply light layers of jelly or anti-corrosion on terminals.Apply enough force to tighten nuts/bolts that hold cable onto ground connection/ solenoid thread.Without any stretching connect new wire very easily into post at topmost corner that connects with electric reservoir and never stretch.Connect red positive first then black negative suggested correct order when hooking up new charger line respectively.
