I am trying to help a friend set up a layout. He has the Lionel ZW (Controller) with 4 bricks. Large layout and using all four channels of the xfrmr. Had a problem with two main lines, one on leg A, other on leg D. Kept getting a short circuit??? Checked all wiring and track pins. Then measured xfmr outputs. Each leg measured 16v to the "U" post. Then measured across the "U" posts, from Leg A, U to Leg D, U measured 32v. I've heard of a "false positive", is that measuring peak-to-peak voltage? Or is it feasible that the transformer is internally miswired??
What was real interesting is a removed the wire connecting the A "U" post and connected it to the D "U" post and the problem went away. OR SO I THOUGHT. Now I have the same problem between the "B" U post and D U post. Any ideas what may be going on??
Thanks
