The TIU is Rev L. Have only used it on temporary layouts in the past. Also only used channel 1 fixed or variable each time. Always powered by Lionel 180 brick and an MTH banana plug cable.
I am now able to install it on my new long term layout and only can use fixed #1. Lights do not come on in TIU if I power through the input of any other channel. Researched the forum and checked the nuts on the inside of the terminal posts and replaced all the breakers with no change. I looked through Barry’s book and was unable to find any settings on the remote that could cause this.
Any suggestions for things I should check to diagnose this issue? Hate to send it out to get it repaired and find out it was something simple as a missed setting or basic repair I could do myself.
