This is a minor note, something I fixed myself but was very confused about for months. My accessory 12V power circuit has been mostly not working since I bought the DSR in January. (This made using GPS on all day rides to locate charging stations rather troublesome.)
The troubleshooting has been very confusing and I've been doing it myself to familiarize myself with the wiring since my backup Zero is still being serviced.
Anyway, after a lot of double takes as I traced out the entire circuit and learned what Burton put together in a more physical way, it dawned on me that there was an assembly defect: the accessory port fuse and wiring was swapped with the headlight fuse and wiring right next to it! I double checked my initial inspection photos after I bought the DSR to make sure I hadn't introduced the problem. (A fuse had blown in the swapped position, whether from troubleshooting or before I ever touched the circuit.)
In any case, here's a photo of the mistaken assembly:
And here it is corrected. Note how much more robust the accessory wiring is than the headlamp.
I've raised my accessory fuse rating from 10A to 15A to support a second port where I can run USB ports and also use a tire pump. I made a hole in the Power Tank plastics to support this and running a charge into a tank bag.
