Absolutely excellent video!! I have an open ground in my 1978 mobile & was trying to figure out how to find out where the ground was not connected. I have replaced almost all the boxes since most of them were floating in the wall paneling & broken. So, as I replaced the paneling with drywall, I replaced the boxes & attached them to the studs and they all seem to be attached to ground properly. BUT I could not find a video that told me how to track down the open ground. This was exactly what I needed. Thank you!!
Hi Rebecca! I always try to make the videos interesting and put a lesson in there too. I love to learn new things. Interestingly, while researching the videos for "best practice" and accuracy of information, I learn a lot too. It's always a pleasure to hear from you. Thanks for watching the videos.
Where was the "phantom" voltage coming from? If no apparent contact was being made between hot-ground, or neutral-ground, and that a 2 Conductor wire existed between the pull chain light and the next downstream J box, how did jumpering a ground eliminate detectable voltage if there's no hot-ground connection found? Very interesting to hear what happened next in the riddle.
Graham has found the answer in the comments of another one of the videos in this series. Here it is: I've now looked at the entire circuit. I found a "shared neutral" between breaker #11 and breaker #12. The splices are the type found on the original install in 1952. They didn't run an extra wire to carry the neutral between light switches (3 way switch in the US - two switches to turn on/off 1 light) and "borrowed" a neutral from breaker #12. My hunch was I'd find something odd at those switches. Here's the link to a KHN video about shared neutrals: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-5agKBtj-v2I.html
After talking to my friend, after having an open neutral, he suggested that possibly a grounding problem possibly outside going to rod or outside electrical box. Bad connection. So I’m going to try that tomorrow. 1/23
Hi John, nice to hear from you. There is a video that explains the importance of a ground wire. None on how to use a multimeter, though there is one that explains resistance/continuity. The videos are organized by playlist, the electrical videos are in a playlist.... click on the channel name to find the playlists. Here's the link to the ground wire video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-RsKWoWvdZ2I.html
Hi Gil. At the very end of the video, I mention that I'll have another video showing how to track down where the voltage on the box is coming from. I'm working on that today. If time allows, I'll have the video posted this week. If you click on the channel name you can see the list of videos on the channel. There is also a playlist tab, where the videos are organized by topic. If you subscribe and I think if you click on the bell(notifications), you will be notified when a new video is released.
Good evening and nice to meet you my friend! I have a diagnostic test that i want to comprehend and apply to the vehicle (2003 DODGE CARAVAN SE) but im not comprehending it. Here is the diagnostic test down below. Check for continuity between each of the blower motor switch input terminals of the blower motor resistor and the resistor output terminal. In each case there should be continuity. If OK, repair the instrument panel wire harness circuits between the blower motor switch and the blower motor resistor or the blower motor pigtail wires as required. If not OK, replace the faulty blower motor resistor. If you are able to help me with this diagnostic test i will greatly appreciate it!
You can do a search for "outlet tester" or "receptacle tester". The one I have is made by GE. If you go to the Know How Now channel and look at the playlists, there is a video that shows how to use the tester to troubleshoot. I don't recall the exact name of the playlist, it's something like electrical repairs, theory. There is also a video in that playlist that shows how to test an outlet with a multimeter.
Here's the link to the video that shows troubleshooting the voltage on the junction box: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-mI2TwFOJlb0.html
