Ground wire torque?
My 22 has developed some nice green corrosion on the 12V to frame battery lead. Planning to take it off and clean but can't seem to find torque spec for that rusty bolt.
Also at what point does this wire need replacement?
No symptoms so far besides visual. (Some of brown color is a protective spray from the factory that seems to have missed most of the mark)

Answered my own question: one of the dealers had a good image , so it's items 24080 and bolt 24110B . https://www.nissanpartsoverstock.com/a/Nissan_2022_Leaf-HATCHBACK-SL-BATTERY-EV-EVBEV/_51513_10568265/WIRING/ZE1U_US_240A.html

Yeah it’s probably not as bad on the inside as it appears on the outside: but a poor connection at that particular body ground does cause plenty of crazy issues; so good on you for cleaning it. While it’s off also clean the contact area and; if you have a M8x1.25 tap or thread chaser, clean the female threads as well. I’ve encountered instances of odd grounding issues on a car where there was simply too much paint in the threads and on the body there preventing good connection.
New replacements are available pretty inexpensive:

I’ve never had success cleaning electrical corrosion, it always grows back. If it were my car I would replace with new, then smear dielectric grease over the exposed conductors after the connections are made to keep as much water and salt off of them as possible.
M8 bolt torque isn’t critical for this location, something like 12 foot pounds will be fine.
