Reply to "Mth 30-1159-1 Wires"

You need to trace the wires, yes sometimes the green is used.  Look at the pad on the engine.  They did not need all ten wires so there will be spares.  BUT blue, gray and red from the 12 pin on engine side are the volume pot and you need to trace there location on the tether at tender side.

Battery had its own red line, but it was shared with blue via a black wire on the blue of the volume pot on some models, but not this one it seems.

From engine on PCB 1 and 2 are coupler, 9 and 10 (wht/Yel) speaker, Need to check but RED and Black at 7 and 8 are probably battery,  Then Gray and blue at normal positions for volume pot instead of tach.  Leaves the one red at 4 which is probably volume pot center.  That red probably is the green wire (normally smoke fan on tender based board).

Always need to check though, many times these get rearranged to compensate for a bad tether wire, so they use another and change positions on the engine PCB.

To test just put engine on track and see if lights and smoke come on.  You could wire battery direct into plug to test motion conventionally too.  But with DCS it should work with motion too.  G
