Hello - thanks for checking out my issue. I've reached the limit of my knowledge and am ready to call in an expert but figured I'd see what the experts here would recommend. I'm definitely not an expert but do feel that I have a solid grasp of the caution and care that needs to be taken while doing any electrical work.
I purchased an older 1950s/60s-era home a few years ago and I have wanted to change the switches that control a Nutone 9093WH multi-function bathroom exhaust/heater/light/night-light. My goal is to put the exhaust on a spring-wound mechanical countdown timer and the other three functions on a single-gang 3-function switch.
I cut the power at the circuit breaker and then double-checked that there was no power coming into this switch box. I unwired the existing switches paying attention to how it was wired. Then I wired the new switches in the manner that I thought was appropriate based on the instructions. When I turned-on the breaker the unit made a very loud buzzing sound that I could hear from quite far away at the breaker-box.
At that point I thought that I had not correctly identified the hot line leading from the panel to the box so I unwired everything and then had all the lines nutted-off and I was going to test to see which was hot. So at this point nothing is connected and the wires are all separate with a nut covering the exposed copper. When I flip the circuit breaker something makes that same sound. As best as I can tell there is nothing else on this circuit to make any noise so I am confused as to how something is being energized with all the wires disconnected from the switches.
I'll provide some pics as well as the rough wiring diagram I've drawn showing how the wires were originally when it was functioning, and how I had wired-in the new switches. Any advice is welcome - barring something obvious that I'm missing i will call in a professional to sort it out.
