@GGG posted:Try Interior light. Again, Markers controlled by LMK are LEDS on front rear of Diesels, and Only Tender of Steam in PS-2 3V unless the board is in the engine like many PS-2 5V were. PS-2 3V steam PR and some fancy RK used a MUX to power the Engine LED Markers and they were not controlled by LMK only the tender. For the early PS-2 5V that had the HL and extra bulb for the Green marker lens, normally it was duplicate off the HL or off the Interior, possible with a Firebox if it had that. Either way, LMK would not control it, and if someone modified a SF all bets are off. Now maybe MTH did something weird with that engine, but I am not thinking so. I bet that was originally powered off an orange interior light and some one may have powered it off the ditch because the interior fet died.
Hook up a 8 pin that has the LED Markers and I bet LMK might control them. G
The firebox glow, which this engine also has, is powered off the interior connector and can be turned on and off with the LFB softkey. Were the 5v and 3v board different in this regard for incandescent marker lights? Again, the engine was originally a 5v, upgraded to 3v, board in engine.
Edit: I tried “interior light on ditch”, and it now works with the LIN softkey. Thanks for the tip, GGG. Now this really has me wondering if the 5v and 3v board differ this way.
