I will start with the wiring shots you requested.
I drew out the harness & Battery assembly in Visio then made it up
as you see in below photos.
This is the Aft Tech Rack Module. I disassembled it from the Fore & Ballast Pump sections so I could route all wiring in a "modular" way, so I can quickly disconnect any of the 3 major sections (if needed to service any of their components) & leave its wiring intact.
As you can see from this photo & photo #3, the BTS gear is not sitting in the speed controller compt. aft. of the motor. It is relocated to the receiver compt. in the Module Forward section. Master Craftsman Frank Ryan gave me this tip. Frank was my first Guru breaking into this hobby..I miss him!
Below is a pic of same module...top view with battery doors open ready to drop in battery packs & connect to harness leads shown in photo
This is a sideshot showing harness assembly & battery packs I made up. The pack you see resting against the Rack is installed from the top just as you see it. You can see how the battery leads along the bottom mate up to the Rack Harness. I included a second battery pack, this one also lying atop my wife's dearly cherished, irreplacable Dining Room tablecloth.
You can see how I constructed the cell pack from the photos. They fit into the Tech Rack very snuggly...no clearance to shrink wrap assembly. Bus Bars & silicone hold each pack together...I am surprised they stay together so well.
More to come....
