This set up has worked well for 5 years. I also run Legacy. No changes before....
This just started happening:
1) Power up ZW-L.
2) All MTH trains start in conventional after about 20-30 seconds
3) Used remote to shut down engine.
4) Once started up the engine is full volume with smoke on.
5) Turn smoke off and decrease volume, life is normal.
Mt thought is a chip or board needs to be reset on the TIU. Problem is that I have to remove the TIU from the backboard to take it apart. I've done it before, but I thought I would ask for pointers first.
