That's exactly what I'm going to do because I haven't been able to reproduce the clicking sound and the concurrent jumping to 14 amps as I showed in the videos in prior posts above. In fact, everything seemed "normal" when I re-plugged fuse F76. I even began to doubt what I had seen - but I watched my own videos and there it was. clicking and drawing current every few seconds.

I suspect it's temperature related or sequence related ... so I need to take the bimmer for an errand with the FSU in, and then watch the battery like a hawk when I get back.

BTW, two (minor) problems happened because of all the connections and disconnections.

1. The negative battery cable won't tighten anymore (I may have overtighted it or stripped it or bent it or whatever - but it was night last night when I realized it wouldn't tighten so I'll look today and snap a photo).

2. The FSU harness connector broke (again), so it now has only one tab and no latch. Oh well, it was a diabolically difficult connector to start with - maybe this makes it easier to disconnect. I'll see.

EDIT:
I WISH there were a good electrical test of the FSU itself, with a DMM.
