Certainly it'd be interesting to do that and some other locations too.
The shots you've already made are way above average.

Your 2.2K seems to be more deeply buried than in my Cosmos PTO's.

There are some truly amazing techniques I've seen used to
document complex mechanisms with Macro photography that
uses progressive lighting/variable focus to do some truly
amazing things with seemingly infinite depth of field. I'm not
volunteering to apply these to my 390A's
but if they could be done the results are STUNNING.

I'm guessing that if it shorted to ground that you would have
blown a fuse (or sacrificed a wiring harness) but it doesn't look
right and it looks like you can do this at the same time as the
2.2K.
