As a follow up i was able to get all the functions to work Puff & Brake with idle at the station, Chuff trigger, Motor Control and Smoke. But then Smoke Died, The Chuff trigger was intermittent, Motor Died and but Puff & Brake / Idle Smoke Fan still worked. I can see how i need a test cable for the harness that lets me measure volts, test for continuity and complete the harness test easier. I will make that cable and rework some of the subsystem components and assure the Engine & Tender bodies will fit nice as well. More later Gang, Thanks for Watching and please subscribe it helps me work toward a little extra parts money. If you want any of the parts you see let me know. I have a few spares I could send out at my cost. Dennis
