I have an older house built in 1973. I have basic understanding of wiring and am smart enough to be safe and complete work with instructions but by no means do I consider myself an electrician.
I'm replacing the ceiling fan in a guest room. In the ceiling box there are three sets of wires.
- 2 white wires capped together
- 2 black wires and one white wire capped together
- a single black wire.
Based on another thread I read, I tried testing the sets with breaker and switch on, sets of wires away from each other and not touching any metal. In that configuration the black set of wires registers hot, the white set is not hot and the single black wire registers hot.
When I turn off the switch the single black wire stays hot and the other sets stay the same.
Seemed to be some shoddy work done previously as there were wires not tightly capped together (pulled apart when I pulled them out of box. Also loose ground wire in light switch box which was an older style LED dimmer switch. The old ceiling fan was very dim and set off a non contact tester when put anywhere close to any metal on the old fan.
I have installed a new standard light switch but am unsure about the wiring in the ceiling box. Is it possible the loose black wire should be bundled with the other black wires and one of the white wires should be a single loose wire coming from the switch?
