So here is what I learned. Grounding the Super Chuffer II (Super Chuffer II, Header Pin 2) to the locomotive frame creates an issue with the ground that yields miltiple chuffer each time the chuff switch cycles. The locomotive frame is electonically isolated fromt he tender frames. The motherboard inthe tender is isolated from the tender frame. The pickups and the grounds form the tender wheel sets both route directly to the motherboard. To get a ground that allows the SCII to work properly in this locomotive only works by using a cournd that routes back to the motherboard - eventually the R2LC Pins 3 & 4.
The electrical theory/physics of this I won't claim to understand but I have resolved my chuff issue. Here is my schematic for the wiring attached for use under a creative commons license:

I have a new issue now, the fan for my smoke unit does not run when connected to SCII Header Pin 6 as per the directions. It does however run when connected to SCII Header Pin 7. I have reached out to GunnerRunnerJohn directly and will add the resolution to that once I have gotten it. I fully exepect to find out that the fan fault is the result of my work and rework around the chuff fault, just as I wacked the Chuff Generator diagnosing the chuff fault to date.
