The isolated outlets may not have a connection to ground. Depending on the version they could be balanced in which the center tap is grounded or the outlet is floating. In either case there is a GFCI on each isolated outlet for safety. Isolated or balanced will drive the normal grounding checker crazy. There may be a switch (some versions) that allow you to select isolated or grounded.
With the power disconnected you can check for connection from hot or neutral to ground.

Geez, it would be easier to have film developed then fool around with all these
cameras with battery life in the minutes. Even new batterys with expensive
batteries, then the propriatary connections that Sony uses.
Trying to find the "right" usb wire that works.

Here is the wiring:
The wires were moved to show how they are connected.
Each yellow brown pair is properly wired even though
it might look like one yellow goes to the opposite xfrms
Here is the 3rd outlet:
Note: 3rd and 2nd use same xfrmr.
Here is the first outlet:
I can't get the pics from the other camera on here which show some different details.

Looks like you have an early example. The transformers are wired in "balanced" mode. You shpould see approx 60V to the ground pin on each of the power connectors Line and neutral connections.

Thanks yes that explains it. No matter which lead was changed
it still had the same reading. I didn't thing of actually
measureing it but now I'll open it back up and double check everything
again. And measure for the balanced line.
Aside from that, me thinks I got her completely working.

Stereo TV testing
Rolled the filter into the living room.
Have to say that it really helped with the
noise floor and seems to crispen things up.
I do know the MKII 7k is not reading correctly.
Its say's I'm running 40+ something amps through
it. That much would start a house fire or melt it
it down. Hopefully it would trip the breaker.
I've had measurements at the breaker box before
and with a larger tube Citation II amp cranked up and all the
lights on in that circuit, didin't pull much current...
something like 3 1/2- 5 or 7 amps max. I didn't log
it at the time. Still plenty of head room.
I'm not sure which internal device measures current or how
to trim the reading etc. Obviously it isn't working properly.
voltage readings are close perhaps a bit high at 123Vac 120Vac.
Not sure if there are some irregularities or flybacks from
the speaker cables or the digital feed cable to my DAC.
I use a cat5 for each speaker, broken out into stripes for
the negative and solid for the positive.
Unsure if and what value resisor I should try terminating them
at the speaker end.
I've got a Marantz CD player changer and run that with a
digital out to the Cursio DAC. I'v heard and read that
the digital line is suseptable to RF and other interference.
I'm thinking of using a small mica cap or polystryene cap at
near the end of the digital cable to see if it can clean up
some of the slight crackle sounds around the edges of the
music and vocals.
I made about 1/2 the interconnects and the digital cable myself.
The others were from a dedicated audio store.
The ones I made are from a special Belden cable that I had to wait
a month for it to come in. I had to buy 100' or 500' reel of it.
Its the Teflon/foamed Teflon stuff let me see what's written on
the jacket...BELDEN-? 89359 I think. Very hard to read and
very stiff tightly jacket and braded cable.
As y'all are aware with enhanced systems
it becomes a double edged sword at times.
About 1/3 the discs I can't stand even to listen
to them any more. Many of the collections
sound like garbage.
Some of the early discs sound very good but
getting the new version of the same disc doesn't
sound the same. Many of the reissues sound crapy.
At some point I should get out the turntable and try
listening to some vintage vinyl.
However, having a well mastered anything on a good system
can be an incredibly moving experience.

Now that the house is quiet and I can actually hear,
the noise floor of my gear has virtually dissappeared.
What's left is the clarity to hear the music,
the good and the bad. I'm working my way
through my referencs.
Speakers are the Klipsch Cornwalls.
Horns externally dampened - automotive undercarriage coating
stops the ringing.
Crossovers rebuilt, updated with paper/plastic in oil caps.
Cabinet centerbraced to the rear.
Rear panel has internal 16 gauge plate steel plate epoxied to it
and batting reapplied.
Then I crank up the music and play along.
It's been a while for me but I did it.
Two faves to play along with are:
Van Morrison - Moondance (frets 3 & 5)
ZZ Top - Fool for your stockings (5 & 10) I - IV
If you don't play much, just play one note on the string
and figure out the change (going to the different fret).
from fret 3 to fret 5.
Then feel your way to the other strings.
The hard part is learning to feel
and learning to trust your feeling.
I play on the other side of the living room.
I set up my 1970s Fender Virbolux Reverb amp
2 x 10 inch Jensen Mod Speakers and play
a G&L Deluxe F-hole guitar.
It looks like a hollow body Fender Telecaster.
It's light weight and had good sound.
This is the method I would use to verify and check
a professtional musician's amplifier after
servicing and updating or modifying it.
It's easy to get something
working again and getting "sound" from it.
It's a whole 'nuther ball game
making an amplifier become an extension of one's soul.
The great thing about the blues is
when someone calls out a slow blues in A
everyone knows how to play it.
