Method of locating defective sockets in a light strand

Abstract

A method of locating a defective bulb or socket in a light strand. The method includes connecting an electric power connector interface plug to exhibit an electro magnetic field thereat for checking its wires for operability of a fuse situated in the interface plug, and traversing an electro magnetic field detector along the non-illuminated bulb/sockets starting with the first non-illuminated bulb/socket closest to the interface and continuing in succession down the light strand until a non-illuminated bulb/socket is located that exhibits an electro magnetic field detection test opposite than that of the previous electro magnetic field detection test. Thereby identifying the non-illuminated bulb and/or socket with an electro magnetic field which is directly adjacent to a non-illuminated bulb and/or bulb socket that has no electro magnetic field as defective. If only this bulb is defective, its replacement will illuminate all bulbs in its circuit. If no illumination occurs, the above regimen is repeated until two non-illuminated sockets having opposite electro magnetic field detection tests directly adjacent to one another are detected. Once again, the non-illuminated bulb and/or socket testing positive (having an electro magnetic field) that is directly adjacent to the non-illuminated bulb/socket testing negative (having no electro magnetic field) is the defective bulb/socket. Repeating the above steps as necessary as indicated by non-illumination of bulbs will quickly locate repair and/or replacement sites.
