ABSTRACT:
A device for testing the cables of a chaff-flare adapter of the type having a base member with a plurality of spaced contacts located inward of the surface of the base member. The device comprises a thin plate means which carries a plurality of contacts in apertures formed therein for engaging the contacts of the chaff-flare adapter. The contacts of the thin plate means are biased outward of its forward surface by coiled springs which electrically short the contacts of the device to ground. Each coiled spring has one end which tightly engages a contact of the thin plate means and an opposite end which tightly engages the rear wall of the aperture in which it is located for providing an electrical path from each contact to the rear wall of the aperture.
