These engines have some very small wires to some of the walkway lights and are not easy to work with when hard wiring them.
Ugh, I know how you feel, I got one of those new fangled Athearn Genesis 2.0 SD90's. All the internal wiring is very fine - and all black! Was an absolute pain to work out what was what.
I plan to hardwire the entire job.
That just might be the easier option. I decided to go looking into all this ScaleTrains DCC fluff and came up a bit short. While I could find the decoder files for the T4 Gevo and SD40-2 I couldn't find them for the Dash-9 or ES44AC.
So what can I tell you all? Not a whole lot...
For the T4 Gevo, which I'm going to presume is the Gevo DaveB is writing about
- According to the decoder file there are no walkway lights that the decoder has an output for. Do they come on with something else?
- The forward ditchlights are on Aux 1 and Aux 2 (pins 15 and 14 respectively) and are power outputs on the LokSound decoder so they should work on a 9 to 21 pin harness.
- The Rear ditchlights are on Aux 5 and Aux 6 (pins 17 and 3 respectively). These are logic outputs on the LokSound decoder and don't have the power to drive the lights themselves so requires trickery on the motherboard to do that. Hooking up an LM output to the motherboard for these probably won't work or could even end up in disaster.
Back to the C44-9W, without the decoder file I can't tell what outputs the ground and walkway lights are on. I rekon it'd be good if someone (not looking at anyone here in particular) traced the wiring out one of these days, especially that motherboard with the dip switches on it.
If anyone wants I can post the pin out for the T4 Gevo and SD40-2.
