I’m looking to find a way to check polarity inline. What I’m doing is I have people build power supply’s for me I have made a tester for them but I cant figure out how to have it check the ac polarity inline. the power supply’s do not have a ground if that helps. I have been experimenting with already available testers u can buy at home depot but they wont test beyond were they are plugged in witch defeats the purpose. Any ideas would help immensely.
