I'm going to merge these posts with the existing topic.

I am definitely not an EE or electrician but I have a multimeter and can poke around a bit

I assume you mean the connector in the bottom right of the below; it also appears two pictures earlier:SageBrush said:What does the connector in photo #9 energize ?

I'm probably way too late to be useful, but the pilot and proximity pins are deliberately considerably shorter than the other pins, especially the earth pin between them. They usually also have black insulation on the ends to make them finger safe, so they can look like they are broken or sunken when they are completely normal. Here is an image (from Ebay, so sadly it won't last) of replacement pins.Timmer said:My problem is the Proximity Detection Pin. It is either pushed in or broken off...
maintenance and refuse to take responsibility. They gave me a quote for $2200 to fix.
winfried said:My Leaf 2012 does not charge with OBC and Chademo works, so I want to figure out if the diode fix or the fix of the diode in the onboard charger could help. I read most of the post:
What I did until now:
- measured Type1-Plug against Earth Pin like in video::
- Proximity Sensor: 4.3 V
- Pilot:
Resistance: 4 MOhm (+ on Earth), no resistance (- on earth)
Diode Test: no connection (+ on earth), 1.77V (- on earth)
- Diode fix:
Inserted diode (HER103) in TYPE-1 Adapter of TYPE2/TYPE1 cable in series for testing: still stops charging after some seconds
Question: Could it be the diode on the circuit board of the OBC like in the video, or something else ?
Since, stated before, resistance of the pilot-ground should be low in one direction, but is not.
DTC 2840
PS: My workshop checked: Onboard Lad/SV-mod, Partnr. 296A0-3NA7A, DTC 2840, electr. fail func., time old,
They told me to exchange the charger (EUR 2500.-)
I am sorry for you, what I did until so far:MrJodie said:winfried said:...

Winfried, same for me.
I lost charger yesterday.
4.3V and 4.5MOhm
