there's a short circuit in CAN-Bus, measured between CAN_H and CAN_L at the plug coming from SimpleBGC.
Can you make a sketch where you measured? I still can not understand what was shorted and how come it could be? Is it shorted incise a Jack wire or in the connector?
Have a look at Motorpixie doc:

I disconnected the Phantom/NAZA cable/jack (or "plug") from BaseCam (SimpleBGC) and disconnected the BaseCam cable/jack from the camera. BaseCam unit was then isolated from other electronics. Then measured (DC) resistance between the two connectors (marked as "green" and "white" in the Motorpixie image -- don't know if colors actually match with cyclops wires) of the jack coming from BaseCam. The resistance was "zero" (or 0.3 ohm, as there's some resistance in measuring tools, Fluke multimeter). These two connectors are part of the CAN-bus (?), which cannot carry messages when it is short circuited. CAN-bus is the "backbone" of the Phantom, see
http://en.wikipedia.org/wiki/CAN_bus .
I did not disassemble the BaseCam, so I don't know what is actually causing the short; may be the socket where the plug coming from Phantom goes, may be the cable/jack coming from BaseCam, most probably a poor soldering on circuit board. Anyway, it's easy to isolate BaseCam and do the measurement. I will not disassemble the BaseCam unit, it would make the warranty void? I am discussing with the dealer for a replacement unit.
