Abstract : Describes a verification technique which greatly simplifies and facilitates the testing of the wiring of wrapped wire electronic boards. The technique contemplates continuity testing of each branch and discontinuity testing between successive branches. After a continuity test for one branch and a discontinuity test with the next succeeding branch, the two branches are then short-circuited. The procedure is repeated with each wired branch until all branches have been tested, whereupon the short-circuit wire may then be removed. The testing technique may be facilitated by utilizing a numerically controlled terminal locator in combination with a computer generated control tape. The technique also contemplates a visual check to verify that all pins on the board that are intended to be wired are indeed wired, and that all pins on the board which are not intended to be wired are indeed bare.
