Still learning the DCS side of my layout.
I have been only using the two fixed channels of my Rev L (Ver 6.0) TIU and not the variable channels. Today I set up my yard tracks on the Var 2 channel (first time it has been used), set to On and Fixed, using it in passive mode. I get no signal from that channel. I switched the wires around, and the other three channels work fine getting the signal to the yard. I put a second TIU in and all channels work.
I'm not sure where the signal generator is connected to the wiring. If it is before the fuse, then I would hope it is a fuse issue. If it is after the fuse, then it may be the generator.
I'm trying to decide if it is something I can try to fix or just send it to someone to fix it. Any recommendations?
