I recently got a ZW-L and a new MTH locomotive that I wanted to test/program in the remote. I had to set up a small test track, since the layout is currently under a massive rebuild. When I wire it up on Fixed 1 I get track power but I get a buzzing sound from the TIU. My TIU is a Rev H2 and didn't have any issues with the previous power setup I had of 2 135 bricks on a TPC 300 so I don't know what could be the issue causing this.
I have tested all four channels of the ZW-L and I get the same thing.
