I refer to that all the time, but I can't see the Bachmann LED, however it's unlikely that they installed it backwards and it worked in DC.
And after installation, I have no headlight. I had one before, and the diagram shows it's an LED and I attached wires to the new board, one by one as I detached them from the old board so I'm 100% sure I got it right.
Wow sound has both a sound mode and a light mode and my understanding is that the light mode should also enable the sounds. I've got good sound but no light. I got sidetracked with deceleration and top speed and chuff rate.
I understand from the directions and one of Tom's prior posts, that the Wow sound has a coast mode, where the chuffs go away when the loco is going down hill or not working. The more I monkeyed with the chuffs, the more they went silent on flat track. I ended up doing a decoder reset and calling it a day. TSC Wow sound decoders don't reset by changing CV 8 to 0, that was interesting, too.

Blue on a decoder is positive for the functioons, common to all.
White is the negative for the headlight.

I'm having a brain cramp as I knew the answer to this once upon a time.
I am replacing a Bachmann DCC board with a WOW sound board. Besides the motor and track connections, which are identically labeled I have positive and negative on the Bachmann and Blue and White on the Wow.
Edit On further googling blue is positive?
Thanks.
