Maybe we can find something else to measure and check, like re-check Fuse F101, and check for continuity on the those black nickel-sized lollypops next to the fuses in the black potted area. Also check continuity across that little glass tube (lightning arrestor) next to that.
Finally got a few moments where my daughter and I could look things over.
1) Fuse F101 - No Continuity
2) Lightning Arrestor - No Continuity
Since I don't have letter identifiers, I'll identify them by orientation, since two are aligned, and one is perpendicular.
1) The two that are side-by-side both showed no continuity
2) The perpendicular black lollypop showed 0.215 mega ohms

@matt: what is the age, voltage and condition of your 12V aux battery--has the car been sitting for an extended time during the covid shutdown, might the 12V aux have been weak or degraded?
Do you remember which EVSE was being used when it failed? Maybe it was charging but never reached FULL?
The 12v that was in it at the time was about 2 years old. I have a trickle charger for the 12v that I would attach occasionally, though it had been a few months since I had topped it off. The LEAF is our workhorse, so we drove it pretty much daily, even through COVID. The car was parked for about a week (while we were on vacation) prior to the charging issue, though it was not plugged in during that time and stored in the garage, which is abnormal, because it is usually parked in the slab at the side of our driveway. When we returned from vacation, I plugged the car into the 240v EVSE that evening. I do not remember if it started charging or not. I believe it likely did because I drove it on a few errands the next 2 days and still had about 60% SOC when I first realized it wasn't charging any more a couple of days later. I then parked the car, knowing I needed to conserve battery power since I didn't know where/how I was going to fix it. When I went to drive it about 5-6 days later, the 12v had died (about 14-16 days after initially leaving on vacation). I attempted to recharge the 12v with the trickle charger, but it kept kicking out an error. I took the battery by Walmart, and they replaced it with a new one (under the 3 year warranty), and that's the battery in the car at the moment. Unfortunately, because the battery was flat dead when I took it to Walmart, I did not get a voltage reading on it (or more accurately, it was likely close to zero).
We almost exclusively charge at home on the 240v Juicebox EVSE, and it would likely have been the one that was utilized when the failure occurred. Unfortunately, because the kids are ALWAYS a distraction, I'm not sure which time it failed (as mentioned above), so it's possible/likely that failure occurred without it reaching a full charge at some point in the 2-3 days after we returned from vacation.
I apologize for the glut of details, but I figured it was better to lay everything out so I didn't miss a critical detail.
