Made some test with getting power out of the hv-bus on a 2012 Nissan Leaf. The idea is to be able to us it for specific v2g purposes where its possible to feed 400v straight in to some 230v appliances which ie many smps can handle, but the tests got a bit wrong and we managed
to connect a 2kw heat fan at the inverter branch of the hv-bus while the precharge wasn't finished. Had some input that it should be possible to get power out of the hv-bus ie from this site even if it's putting power in and at a different end of the hv-bus and from a few people in to the industry. And hade some things running successfully before this happened.

where the precharge is blown and short out and as I understand a fuse in the dc/dc junctionbox is also blown.

which got the same brake/abs errors but not the ev/hev and ends up changing a relay/contactor in the battery box and "sofware upgrade" a the nissan workshop.
Hope to get some helpful input even when the fault comes out of stupidity.
