Well, I finally ran the tests. Don't know if I did it right. When I put the leads together, the meter went wild, from over 180 to a low of 2.0 when I barely touched the tips together. May be because it is a cheap Cen-Tech digital multimeter, but it is new. Zero volts and 8.5 ohms, but nothing is connected to any wall jacks. Two of the wall jacks are hard to get to. I just took off the phones and left the cords on the jack. Would this make a difference? The tests were done on the wall jack that shows on shook status with the obi. The other jacks gave off hook status. There is no transformer in my 1970 house. In fact, all the wires from inside the wall have red, green, yellow and black wires, same as the jacks, making it easy to connect correctly.
