When the game is running, should there be ANY voltage measured across the terminals of the coin switch at all? Meaning, if you take a multimeter and touch the common terminal and the NO terminal on the switch with the leads, where the wires are connected from the harness, should there be any reading there at all when the switch is open (not receiving a coin)? What should the voltage read when the switch is closed (by holding it down with your finger). Standard Asahi-Seiko mechs and rectangle coin door with no lights, etc.
