I need some troubleshooting tips here. I have a customer that is experiencing flickering lights, but not in anyway that I've ever seen or heard of. The lights will brighten, then dim and a small tv in her kitchen will shut off.....when does this happen? Whenever she turns on her jacuzzi tub. No new work has been done in this house in the past ten years. The tub is on a dedicated circuit. The tv is plugged into a circuit which is on a different leg from the (110V) jaccuzi circuit. Any ideas? Or is this the utility company's problem from the pole to the main? I didn't read any voltage fluctuation when the tub was turned on (but then I don't have a digital meter either). By the way, the weatherhead was truck by lightning 2 years ago, but according to the homeowner the entire service was rmoved and replaced to code.
