I once did a service call at a house built pre-1940. The owner was having trouble with a cieling fixture, in the hall way, switched from both ends. After disecting the wiring in half of this house, I finally figured out how the original electrician wired this 3-way switching. A few of the old timers I've talked with over the years called it a Chicago Hook-up. Anyone here know what that is? We're talking knob and tube days ok?
Thanks guys, I can see where the same subjects would come up every so often. The trade has a wide scope and there are almost always more than one way to get an acceptable result in the field. Throw in the fact that there are so many members to this forum and some topics have to come up over and over. Although, I still haven't seen anyone post the answer here. heh heh. Just kidding. I'll give you guys another riddle in another thread if you like.
I checked the link above and didn't see anything about the chicago hook-up however, there is a referance to a third, illegal way to make a three way system work. I'll accept that the person who wrote about that probably knows what it is. For those that don't here's a hint. It is illegal and doesn't use travelers.
