sorry, I am new to this site. I am in Northern New England (NH) I have added a couple pics. Any help would be greatly appreciated!!
20 amp circuit at the panel. On one wall in my kitchen by the side door are two 3-way switches. One controls power to lights outside in breezeway, one controls two lights in the kitchen.
In the ceiling, there are three cables coming in. I assume one to the other 3-way switch by front door, one to the 3-way switch on the wall with the second switch I mentioned and the third I think is all the power to the garage, breezeway and outdoor lights. If I connect a light to the ceiling and to the wires that run to the two 3-way switches, everything works fine, but I have no power to the garage. If I connect all 3 wires in the ceiling and a light, the two lights stay hot (N) all the time and I have power to my garage and have to unscrew the lightbulbs.
Somewhere, someone wired a fan with light to the ceiling and unscrewed the second lightbulb to make this work... Kind of.
In the wall by the side door with the two 3 way switches, there is a bunch of wires and nuts in the box. Whites all nutted together and various combos of red/ black to the two 3-way switches. Also a combo of probably 80s two-wire with a ground and old sheath with no ground
Hopefully I explained it correctly and this is the only wiring problem in the house that has stumped me and beyond my skill set. There is also nothing grounded at the switches by the side door that I can see, there is a ground wire grounded in the old metal box from probably some time they partially updated or added the garage.
