Hi Lou, I went out and switched everything from my Z4000 from fixed to var1 & var2. I also switched the input to the TIU and output to the track. I tried and all that happens is the horn blows on the conventional engine and the DCS engine on the same track starts up.
I also get a reading on my Z4000 in the amps window AC. I hove no idea what that means and there is nothing in the Z4000 manual about it.
Any help would be great!~
