Hello everyone! So, I've learned a lot from reading trough this forum - and have determined I have a "loose neutral" situation. Somewhere. Here's the scenario.... and thanks in advance for all comments and suggestions! This is a very old country house that's probably been added to and modified electrically over the years. I'm certain there are 3-prong GFC outlets where there is no actual ground wire - and I know this is an issue, but not the one I'm fighting with now. What's happening is that under certain appliance loads (mostly seen when electric heaters cycling on) - EVERYTHING in the house on every circuit starts clicking on and off, lights flashing, and a couple satellite TV receivers (on different circuits) got smoked. After reading many other stories, it sounds like a loose neutral. So, my thinking is that there must be a loose neutral wire in the "main" panel outside the house or possibly a bad connection to the "sub-panel) inside the house? I'm thinking this because all 9 circuits inside the house seem affected at the same time - and I've had appliances fail on completely different circuits, even ones that are truly grounded and testing normal using a three-prong tester. Also, using that same three-prong tester, I see that most of the receptacles test "normal" but several do test "open ground"... but again I don't doubt this as I know that these were installed where there isn't a ground wire available. None of the receptacles tested gave me an "open neutral" reading though, which also has me puzzled. Based on what I've described here - am I correct in thinking it might be a loose neutral somewhere affecting the entire house and every circuit?
Thanks so much!
