Not quite a cigar yet, but getting closer, apart from still need to work out where to wire the rear lights and cab light too, the sound card is now in and in theory chuffs to the fitted sensor as that is wired to the smoke unit then the signal out from that is wired to the sound card. so it was testing time.
But it doesn't quit sound right, when you turn the throttle the smoke get does what it should do and starts to chuff out smoke when the Loco moves. The sound card starts to chuff when you turn the throttle before the Loco moves , then when the Loco moves it adjusts it's chuffs to suit the actual sensor and is then in sink with the smoke unit.
I assume it is CV 935 in the sound card that needs changing to rectify the problem as I assume it is set to automatic and wheel sensor, but I have no idea how to change bits ?
The two red wires dangling with masking tape on the end are the live from the smoke unit sensor output and the live in to the sound board I didn't connect that pair, as the Massoth instructions sort of say you don't connect the Red wire so I didn't
