I still am amazed that the chuff switch can do what is being illustrated, but knowing the electronics of the early Legacy, I don't see how the electronics would do that either! Skipping four chuffs in a row like that is really odd. I wonder if this is the case where they're getting one chuff from the switch and the articulated sound is generating a bunch of them. That would explain missing every other one if the chuff switch was only hitting half of the lobes.
That could be. The issue I was having is the wire running to the DCDS was missing the resistor. The new assembly with that resistor, a fresh cherry, and clean wiring seemed to fix my issue. You also have to remember that all these old modular setups are strong boards, but they are a little odd in their operation. They activate the smoke and Chuff different from tmcc, they have the whole smoke reg setup, and overall is much more old school in design than the RCMC setups we have now. Sometimes the simplest things can make a big difference.
