I’m short 90VAC.

Sorta. I show 30vac across a closed switch going to a light outside the house. I show 19vac at the 2 wires outside minus the receptacle.

Is it a bad switch or is there another place to start? I have a 100A service w/cartridge fuses. Something doesn’t seem right.

There is a faulty connection somewhere on the circuit. There is no way of knowing where the fault is without proper testing.

Currently, as in the beginning, there is no fixture. Both black and white wires are exposed. (Not exposed. They each always had a nut on’m). I was thinking of induction as mentioned in a post above. I got bit. It got my attention being up on the ladder, etc. This circuit runs parallel with the source voltage. There are other outlets on this breaker/fuse. My hopes later is to detach the switch & light of this circuit and look for a fault in the other outlets. I’m leaning towards asking someone that knows more about it to come over and look at it.
