                         HOW TO REPAIR THE OLD COIL-CORD CONNECTIONS:

For flexibility, every  "ONE"  of the 3 wires consist of many threads
of thin wires,  wound around cotton strings  and there are more plain
cotton strings for durability. There is no way to solder these wires.
Cut the damaged cable away.  Remove 2" of the outer  and  1/2" of the
inner insulation.  Carefully separate  the  "wire strings"  from the
plain cotton strings.  Cut the  cotton strings away and fold the wire
strings back parallel to their insulation.  Than press it in the OLD,
UNFOLDED & CLEANED metal hook connector to have the electric contact.
