Forgive me if this is easy to search - I was not able to find anything obvious here or on YouTube. I've got an outdoor circuit that has failed. Specifically, one outlet failed and then the second one went about a year later, with no trip of the breaker. How do I test the wiring to make sure it hasn't been corroded etc? The obvious thing that comes to mind is to test the resistance using a multimeter and compare it to an indoor circuit of similar length but I don't have a one hundred foot long lead to span from edge of my yard to my panel... There must be an easier way, right? The other thought is just to get a voltage reading and again, compare it to a good outlet, but I'm not sure that's a sensitive enough test. I don't want to go digging up my yard willy nilly without evidence that the wiring is bad. Thanks for advice.
