    Hi,
    I am attempting to design a continuity tester that can test continuity on a single wire without having return wire, Eg plug one box into one connector on a control unit in a factory say and plug another box into maybe another control box across the other of a factory to check continuity of a wire between the 2 if there is continuity maybe a led light comes on or a simple buzzer.
    I have very little electronics knowledge so any help would be greatfull. I was thinking of trying to transmit rf down the wire to a reciever but I don't really no..
