Just so you know ... I was hoping that Leaf Spy would tell me how much current I was sucking from the 12v system; yet I'm only seeing less than an amp. Helpful respondent at the Leaf Spy support thread pointed out that it's because I connected the inverter's '-' input to a chassis bolt (as you're supposed to do), not the the battery's negative terminal.
You would have detected the current if the car was turned ON such that the VCM was energized. i'm not sure if this occurs in Accessory Mode or if only in READY mode. Although i would think only in READY mode since the main contactors must be engaged in order to operate the DCDC converter which recharges the aux battery.

If you connect directly to the negative terminal, then the current sensor is by-passed and can not measure the external load.

The FSM Caution note about not connecting to the negative terminal directly is because an external load attached for an extended time could drain the 12V (and excessive drain could damage the aux battery).

evtifosi, could you add a few pictures detailing connection to battery positive and your fuse?
Curious which bolt you tied to on the battery.
Btw, negative into "engine block" might be 8x1.2mm if my memory is correct
