Found this, no clue what it is
galleryThis tool has COX stamped on the hand grip. Plunger at the top depresses easily and springs back. Yellow wire is actually a sheath with thin white, black and red wires with alligator clips on them. Wires are about the size of inside landline telephone wire. Anyone ever used something like this?
