I original had my Lionel zw-l connected to all four channels, I was setting up a five channel with a another tiu for layout expansion. Wanting to use the zw-l for the new tiu I powered the fixed channels on the original tiu with two Lionel 185 watt bricks connected to the fixed channels on the original tiu and the variable channels powered by the zw-l. Once I did this I had no power output from the tiu on the variable channels. I read Barry book and took the tiu apart to check the fuses. I did have one blown fuse which I replaced. Then I re installed the Tiu and still had no power output from the variable. I check the input power to the variable channels and it was 18 +. Reading the book again I did a factory reset to the tiu and still had no power output from the variable. I check the controller and set the variable to fixed and still no power. I then set the tracks on the controller to 22 voits and still no power. Thinking it maybe the tiu, I installed the new one and have the same issues.
Any help would be appreciated. My gray hair is now falling out.......
