Damage is done. Where there is a small coil and you look at the back side of the board you can see discoloration and it smells burnt. I just don't understand it. Test went well with the Z4000 after we fixed the motor wire problem. Set up in the computer room another test track with the CW80 and the TIU and Computer. Did one more check on the Z4000 test track and it performed just like the book said.
Set it up on the computer test track and followed the directions to do the download and power it up. It just made a buzzing sound and I shut it down and re-powered and notice the Green light on the CW80 was out.
Lionel CW80 also must of burned. No smell, but no power out. This the second CW80 this has happen too. For some reason MTH train engines do work well with it.
