1. A test lead cable retraction system comprising:

  • a base, said base having an upper surface, said upper surface generally lying in a plane;

    a pillar, said pillar being fixedly mounted to said upper surface of said base, said pillar having an end extending away from said base;

    a first bore, said first bore extending through said pillar;

    an axle inserted in said first bore, said axle being fixedly mounted in said first bore, said axle having a first end and a second end;

    a first spool for holding a test lead cable, said first spool being rotatably mounted on said axle, said first spool being generally located between said pillar and said first end of said axle, said first spool having an outside edge;

    a second spool for holding a test lead cable, said second spool being rotatably mounted on said axle, said second spool being generally located between said pillar and said second end of said axle, said second spool having an outside edge;

    a pair of rings, one of said rings being mounted on each of said outside edges of said first and second spools, each of said rings being formed of an electrically conductive material and having an electronic connection thereon, each of said electronic connections extending through said outside edges of said first and second spools toward said pillar;

    a first biasing means for rotationally biasing said first spool against rotation with respect to said axle in a first rotational direction;

    a second biasing means for rotationally biasing said second spool against rotation with respect to said axle in a first rotational direction;

    a first connecting cable, said first connecting cable having a first end being electrically coupled to said electrical connection in said outside edge of said first spool;

    a second connecting cable, said second connecting cable having a first end being electrically coupled to said electrical connection in said outside edge of said second spool;

    a first electrical contact, said first electrical contact being abutted against said first ring;

    a second electrical contact, said second electrical contact being abutted against said second ring;

    a first linking cable, said first linking cable linking said first electrical contact and a meter; and

    a second linking cable, said second linking cable linking said second electrical contact and said meter;

    wherein said base has a first side, a second side, a third side, and a fourth side, a first end and a second end.
