Installing on a 3rd rail sunset steam engine the Cruise Commander and Rail Sound 4.0 are mounted in the tender. I have plenty of room in the tender for the Super Chuffer. I have a four-revolution or two-revolution microswitch a hard wire tether. The trigger sound on the Rail Sound 4.0 board is connected to the two-revolution micro switch. Works great and no problems. I installed the Super Chuffer per instruction checked wiring and it did not work I check continuity between each wiring connection and all are ok. I then tried connecting just the smoke unit with the Super Chuffer not installing connections to lights. Here are some Photos what I am doing. I took all connections out because not sure if I have the right schematic. The fly wheel does not work unable to program.
