Abstract
A wiring test system in which test probes are to be oriented to engage contact points on a production circuit board, a wiring integrity verification plate comprising, in combination: a thin insulative base plate, multiple contact pads and leads attached to the plate; each of the leads extending between and interconnecting two of the contact pads, whereby multiple circuit sections are formed on the board, each circuit section including two pads interconnected by a lead; the two pads of each circuit section respectively located to be contacted by the probes of the wiring test system for providing an electrical continuity test via that circuit section, when those two probes are correctly located relative to contact points on production circuit board for testing the production circuit board.
