[Ovmsdev] Nissan Leaf ZE1 - Total loss of power

[Michael Balzer]

Chris, Wayne,

you can help by testing switching off the SN65:

https://github.com/openvehicles/Open-Vehicle-Monitoring-System-3/issues/980#issuecomment-2715850440

As Richard wrote, he could not reproduce the issue in his Leaf by that, 
but on his bench. If that's the culprit, there still is the Housekeeping 
SN65 switch-off to address, but there is probably little we can do about 
cold boots.

Regarding floating voltages, see Richards followup post.

Also I suggest asking Richard how you can help in narrowing this down.

Regards,
Michael
