Glad you were able to work it out. The chuff switch is kinda' buried by necessity, they logically need to be on an axle to be synchronized with the drivers. You were lucky with that wire, the chuff switch works by grounding the input, so pinching it didn't endanger electronics. Pinching other wires to the frame frequently has more catastrophic effects.

I don't miss the chuff switches in newer Legacy, that's for sure! I have my Vision Line CC2 waiting for me to fix the chuff switch, and it's buried under everything, you practically have to disassemble the locomotive to get to it! The new stuff with the RCMC electronically generates the chuff from flywheel rotation.
