I was asked to install a PS 3 2 Steam Kit (50-1911) into a 4-8-4 L-3 Mohawk Rail King 30-1497-1. All systems checked out on fire up, Sound, F/R, Smoke, Couplers. Then I installed the newest PS3 sound set from 30-1829-1 (2019) and the heating element does not heat up. Yes the the fan is working. I then tried 30-1652-1 (2014) and no smoke. Then PS 2 30-1558-1 (2010) and still no smoke. Each of the times above I cycled on and off and did reset (Whistle and 5 bells) several times. Tests were in conventional. I then put in a Diesel sound set and now it smokes great just like in the first test. Boards have 4922 on it, if that helps. Boards are from a new steam kit so I am assuming it has the correct Steam chain file.
Any suggestions? Thoughts?
