[QUOTE="Geoff1946, post: 492715, member: 28452"] Your meter is a high impedance device designed for testing electronic circuits. This means it will pick up and display capacitively coupled voltages; - that's what you are seeing across your main switch. All totally meaningless . No indication of any fault there. If you have problems with leds glowing when off this will be local to that circuit and also probably harmless. (I love Kerching's subtle hint that you are putting yourself in harms way. - Do be careful!) [/QUOTE]
