I have been doing some electrical work in the garage in my backyard to add a switch and more lights. I had to do some re-wiring and now there is something that is not working.
the garage has 2 underground cables that are powered by the same breaker Inside the house). 1 of the 2 cables is controlled by a simple switch inside the house. The first cable (let's call it A) powers the garage and does not have any problem. The second cable (let's call it B), that is controlled by the switch in the house, powers 2 separate circuits: a garden pole (B1) and a light fixture on the steps on the side of the garage (B2).
to do my tests I am using a Klein Dual Range Non-Contact Voltage Tester (simple device) http://www.kleintools.com/catalog/el...voltage-tester.
when the breaker and the switch are on, but the 2 circuits (B1 and B2) are not connected, I can test the voltage on cable B (which, by the way, is an old wire; like the ones that run inside flexible metal conduits and are covered by something that seems like a cotton tread rather than plastic). during the test, I hear a very fast beep if i touch one of the 2 cables and a not-so-fast beep if touch the other wire of the same cable (B).
after i connect any of the 2 circuits (either B1 or B2 with black, white and naked wires.. more modern), both wires seem to be loaded because they have the same "very fast" beep when I touch them with the tester.
The lights do not work.
bottom line, it seems that both wires are hot only after i connect any of the 2 loads.
what can it be?
