I'm watching Richard replace a dishwasher here and he uses (I think) a digital mulitmeter to make sure the dishwasher was correctly marked in the electrical box. I've flipped off the power but I'd like to test the wires to make sure it is off. I just bought the home and am not sure if the things are correctly marked.
Can someone please tell me how to use the digi multimeter to test the wires?? Or is this the wrong thing to use for this purpose? Thanks for any help!
