    Abstract: A test lead retraction system for retracting test lead cables on a spool. The test lead retraction system includes a base having an upper surface, a pillar is fixedly mounted to the upper surface, and a first bore extending through the pillar. An axle having a first end and a second end is fixedly mounted in the first bore. A first spool and a second spool are rotatably mounted on the axle between the pillar and the first end and the second end, respectively, of the axle. First and second biasing mechanisms rotationally bias the first spool and the second spool against rotation with respect to the axle in a first rotational direction.
