    Testing voltages on light switches

    Hello guys. I have a question as being in Africa for 15 years, I used to use a mustimeter to check voltages at the light switches as they got neutral and lives inside the switches, however when I moved to England I found out that there is no neutral at the switch as the neutral goes to the bulb...

    Hi, I’m just wondering what sort of readings I can expect for faults on a multimeter? I’ve only ever used a multifunction tester. What readings can I expect for a short cct fault or a polarity fault? I know that open cct will be 0L/1, cheers

    I just built one of those steampunk pipe lamps. I was assembling and testing connections via resistance and a multi meter. Everything went well until I added the rotary dimmer switch.
