... with nothing plugged into the Leaf, there will be about 4.5V on the proximity pin to ground... that has to come from a 5V supply, presumably in the On Board Charrger. So there must be a wire all the way to the OBC.
There is a black wire pair, it can be seen in the AC connectors picture on page 1 of the OBC peek under the covers thread,
skip past a bunch of blather to page 13 to find an inside view with the cover off,
The black wire pair runs to the top board on the right hand side edge connector, pins 1 and 2. There is another connector below it with a black dot with a red wire pair on pins 3 and 4 that runs to the HVDC connector to the pack. You can see the red wire pair in the DC output connector.
i don't hear the Blinnk L2 EV_SE contactors, nor the car's main contactors snap off, when pulling the trigger. There is a small AC relay in a potted doghouse on the bottom board of the OBC which you could never hear--maybe that is being used to break the AC connection?
What could possibly be the benefit or reason to leave the contactors in the EV_SE and the car unnecessarily energized after getting the trigger release signal?
But i'm glad to hear that the current gets commanded to zero.
