Thank you John,
Susanne and I are heading down to Dale's in the morning, they are a Lionel Dealer. I will see if she has a replacement C08-S1, or we can test this one while we are there. I'm just not at the point to commit to converting the other two engines to ERR until I get the lights and ditch lights fully functional on this engine. What's really weird to me is the lights are functional in conventual mode...
I'll see if Chris can take a look at this board, it looks like it had rework done around D1 up to U8, there may still be a small solder bridge right there...
I will update when I get home tomorrow...
