Electrical Wiring in the Home/Old Wiring

Question
hi. I'm replacing an exterior light fixture. The house is old and has knob and tube wiring. When I took the old fixture off I noticed that there were two hot wires and one neutral. Of course there is no ground and no color coding since it is knob and tube. The old fixture had two bulbs so the two hot wires coming from the house and the two hot ones coming from the fixture were all spliced together in one cap. I want to replace it with a one bulb fixture. Can I splice the one hot wire from the fixture to the two hot from the house which are already twisted together or should I cap one of the hots from the house and only splice to one?

Answer
Henry,

The two "hot" wire's twisted together coming from the house says to me there is another light fixture besides the one your replacing that is controlled by the same switch or at least there was another fixture at one time. Having said that you would indeed splice the one "hot" (black) wire from the fixture to the two "hots" from the house.

Education/Credentials
"The Frank Williams School of Electrical Construction". My dear old boss is 100 ! and still going God Bless him. I started working for "Tenafly Electric" right out of high school at 19. He was tough but I learned more working for him in 8 and half years than most guys. We did mostly industrial work while doing some commercial and residential so I was fortunate to be exposed to all 3 areas of electrical construction. The guys I worked with were all good guys and I stay in touch with some of them still. Most of us went into our own buisness's which says something about the caliber of the guys I worked with. We had some interesting clients : Wella Corp. of shampoo fame, Farah Fawcett etc, I didn't buy shampoo for 10 years. It was a great place to work. Pan Am the former airline just before they went under, another great place to work, nice clean environment. C&C Metals, the largest button manufacturer in the US at that time, a not so clean environment but a very interesting place to work, lots of machine's cranking out buttons of all kinds but you had to be on your toes, it was a potentially dangerous place to be . All kinds of action going on around you.
