May I ask a dumb question? Does the light switch light up when it is in the off position? These use power when "off" and allow somewhere between 12-24V of power through when "off"(which isn't enough to light a main room light). |

Digital multimeter? 46 volts? Very possibly noise. Try this: Make sure power is off. Insert meter probes. See 46 volts. Its probably noise. DMM's pick up everything. If it were me... I'd take a 100w lamp and plug it into the other side of the outlet as a load. If the voltage drops to zero, its noise. Voltage, yes, but currentwise in the milliamp regions. |

Seen low batteries on a DMM do weird stuff like that too. --- Quote from: Ed_McCarron on September 07, 2009, 08:18:21 am ---If it were me...

Hi Bungy, What voltage readings do you get on your wall outlet between the live and earth and neutral and earth? It sounds to me that you are getting a voltage on the neutral between earth. So it could be the earth bonding somewhere in your household that is the issue or that the bonding is not good from your supplier. Regards Alan Hood ami-man UK |

But what concerns me is that in my full setup (two outlets, one outlet switched (where I read 46v on the switched one)) when I plugged in my monitor when the switch was off, I heard a click as if the monitor were trying to turn on. That doesn't happen when I plug it into a power strip with its switch off. I think I'll try to bring the test rig to work and measure it to try to eliminate my home's electrical system. Otherwise my theories at this point are that I'm using a bad connector for the incoming power cord, or the power cord itself has a problem. |
