![]() One is whether the hot or the neutral is open. There are two matters important to finding the bad connection. Since an open is an unintended discontinuity, locating it can involve experimentally disturbing connections till the bad one makes good contact again briefly or else deducing fruitful places to look for the discontinuity. If you have reached this page without beginning at the Start of the diagnostic tree, you may do better to start there. Thank you.Diagnostic Tree: Broken Circuit (Open) Finding Your Open Hot or Open Neutral Please let me know if I haven't provided enough information or should clarify. I appreciate very much anybody taking the time to weigh in. As I said, each double pole switch is on it's own circuit. One is powering two switched outdoor GFCI outlets. ![]() These are 15A circuits and 3 of the 4 switches are just powering lights. My question is, is there any problem with me simply running two sets of 12/4 or 12/2/2 romex instead of two sets of 12/3 up to the double gang wall switch and tying the neutral into the separate pigtailed neutrals that are now bypassing the switch? Therefore, the new wires would carry line, two loads, and a neutral (and ground) instead of just the line and two loads (one of which was on the white wire) and a ground. I need to add one neutral to each switch (to add double pole smart switches to each). So what they've done is put two 12/3 romexs on a double pole switch by ditching the neutral and using the white wire as a load line above. The lines are also pigtailed and then head up to the wall switch. These two 12/3 romexs are from a nearby accessible (unfinished basement) junction box with four romex 12/3 romexs coming in the neutrals for each set of two 12/3 romexs are pigtailed together and do not go up to the wall box. Each double pole switch therefore has one line coming in and two loads going out (the white wire is being used as one of these so there is no neutral for either switch). Each switch is on a different circuit (but each pole on the same switch is on the same circuit) and supplied with a 12/3 romex. I have a two gang switch box that has two double pole switches in it. ![]() I was hoping to get some advice on the following: Can I cap the current lines the outlet is on and put some pigtails on the other run and connect the outlet that way? No idea where the other line is feeding either. The box where the outlet is also has another line in it that is not attached to the outlet (see attached photo). However, I thought I may have another option. So I'm not sure how to go about tracking down any potential neutral disconnects besides opening up a bunch of outlets and switches. So I'm not sure where this outlet is getting it's power from. I checked a few outlets on the other side of the wall, but all the outlets I checked were the end of the line outlets. And a non-contact voltage tester indicated there was voltage on both the hot and neutral. So I thought the neutral is disconnected somewhere downstream. An outlet tester indicated that I had an open neutral at the outlet. The outlet wouldn't reset, so I figured it was an issue with the wiring. I replaced the outlet with a GFI outlet but still didn't get power. ![]() One of my exterior old outlets wasn't working, so I figured it was a good time to replace it with a GFI outlet.
