Some of you may recall the specific and pointed DEMANDS that nmra color codes be adopted throughout.
Stanley assured us that the color codes were.
They are not.
Of the colors of the 13 wires from engine to tender, exactly three match the colors in the tender to the Ames Super Socket.
Three.
Let’s start at the motor.
Those are red and black (wrong, but as supplied by Pittman).
From the bottom firebox board, the are black and green. When they jumper through the upper firebox board, they become orange and gray, which is correct. However, in the tender, going to M+ and J1-3, they are orange and tan (or brown).The headlight control, J1-4, starts at the board as tan (or brown), becomes orange at the tender plug, and when it comes out of the end of the upper firebox board, it is black.
I have the full schematic. Took some time to draw. And, I would be willing to bet that the next unit’s colors are different.
How are we to work on these when the colors are that messed up?
Oh, and if you unplug the two plugs on the upper firebox board that have 14 wires to the smokebox board, you lose your flicker.
I have figured out what they did, and know which two pins to jumper.
I am NOT happy to have a forced-to-use protocol where hidden “safeties” are in place to preven us from doing what we want.
I fall back on my original, it is cut and throw.
Fortunately, they provided enough redundant wiring between engine and tender, I can drive the flicker from a Sierra and be quite happy.
Even have a “smart” flicker.
