With installation of the CC-M board and the help from you guys, the engine is great! So on to today's issue.
On another long dead K-Line switcher, in a replace all Lionel TMCC components with ERR stuff Sunday project, I installed a Cruise Commander and Railsounds board. For chuff and smoke, this engine has a cam on a drive axle, a Normally Closed "big" leaf switch it activates, and linkage that pushes a piston to blow smoke puffs, I assume. No little reed switch involved. (I NEVER, EVER have used smoke capabilities, because I have very scary instructions not to.")
According to the ERR instructions, to obtain locomotive chuffing sounds, the Railsounds board is connected to the two reed switch leads, unless synchronizing with a blower type smoke unit. In that case you connect something to the 'Chuff In' on the CC board. No reed switch connections to the sound board in that case.
I don't even know what a synchronized puffing smoke setup would look like, but I assume this switcher does not have it. There were only three wires involved in the previous chuff sounds and smoke capability. Two to the leaf switch and one for the heating element which is grounded.
So, my question is, why can't I use the existing leaf switch leads for connection to the ERR sound board? I tried it, and in the 5 seconds of run time of the engine I heard two double chuffs per driver revolution instead of two chuffs per revolution. Just wondering why.?? 
Thanks.
Thanks.
