I'm absolutely confused. I'm trying to replace a switch. Switch has 3 screw terminals. Hot, Load and Ground.
Ground is correct. If hot and load aren't on the right screw terminals the switch won't work. Other wires aren't easy to tell which are which but I tried one way and it didn't work.
I checked with my multimeter measuring voltage between one screw terminal and ground and found which side had voltage. So I reversed the hot and load wires on the screw terminals. Still nothing and even though I switched wires the when I measured voltage with my meter it was still the same screw that read the voltage even though it had a different wire on it!?!?!?!
I redid the wiring twice on each side just to make sure.
Older home built around the 50's. No neutral wire at the switch box. Any body have any clue what's going on?
The switch requires a proper ground to work and that might be the problem but I'm still confused. I used a grounding pigtail temporarily to test the switch connected to the back of the box. 2 conductor armored cable goes to the box. Old cloth wrapped type wires. Disconnected switch and checked voltage between each wire to ground. Got about 70V for one and about 40V for the other.
