Chuck Sartor posted:That's going to be a formidable wiring job. The PS-1 board is going to have to control the loco to get the chuffing sound of Proto one. Which means a long tether to the locomotive through the tender. If the motor is disconnected from the circuit, you normally get a uncontrollable rapid fire exhaust sound. I'm not sure if the resistor added will screw up the chuffing as it will see the motor drawing a heavy load. I don't see it as working out.
One of my original ideas was to just leave a motor hooked up to the board and set it on it's side so it can free wheel in the water tender unhooked to anything, but retain the proper control over the sound corresponding with the voltage applied.
I could probably also add a blade or fin to the edge of the motor and essentially turn in into a cooling fan for the whole QSI board - creating a dual purpose.
