I think I have a bad channel on my TIU. I've been running it for about 7 yrs. My layout. 2 loops, ZW-L for power and a TIU Rev.L. Power to the Loops are via Fixed 1 and 2. I've had no problem running either Lionel or MTH engines on the tracks, even with both on the same loop. Last weekend I put an MTH engine on the track and it only ran in conventional mode on Track 4 powered through Fixed1. But on the loop powered through Fixed2, it would wait after power up for a command. So, it was receiving a DCS signal after track power up. Same result. The track connected to Fixed2 passed the DCS signal, the other, nada. I used the Remote to turn each chanel on an off in the System menu. Same result. Am I correct in concluding Fixed 1 is Kaput? Can I fix it?
