Clean ground

Thanks for the info @oldhvymec. I’m googling for some more info on this at moment

You said:

Correct.Nothing touches a wall socket with the exception of the three prong plug that provides access to ground.

I charge when I’m not listening.

In the rare event that I want to take input from, or output to, a device that is plugged in on a wall socket, I use an audio engine Bluetooth connection. There is never a physical connection between components on battery and components on mains.

1.) I have active cables that do not work if not connected to ground.

Question:
Does both battery(s) pos B+ and neg B- float with no reference to the metal chassis of any of the audio equipment that is connected to the batteries?
B- is not connected to chassis?
Metal chassis would act as an antenna I would think if it was not connected to B-.

1.) I have active cables that do not work if not connected to ground.

I am having trouble seeing the loop, closed circuit, to mother earth ground and back to the source, the batteries.

Test:
Measure for DC voltage from B+ to chassis.
Measure for DC voltage from B+ to metal enclosure of battery charger. (charger left connected to battery(s).)
(I assume charger uses a 3 wire cord and grounding type plug.)

"Electromagnetic Compatibility Engineering"

Grounding Myths

4. To operate with low noise, a circuit or system must be connected to an earth ground. False, because airplanes, satellites, cars and battery powered laptop computers all operate fine without a ground connection. As a matter of fact, an earth ground is more likely to be the cause of noise problem. More electronic system noise problems are resolved by removing (or isolating) a circuit from earth ground than by connecting it to earth ground.

5. To reduce noise, an electronic system should be connected to a separate “quiet ground” by using a separate, isolated ground rod. False, in addition to being untrue, this approach is dangerous and violates the requirements of the NEC (electrical code/rules).

6. An earth ground is unidirectional, with current only flowing into the ground. False, because current must flow in loops, any current that flows into the ground must also flow out of the ground somewhere else.

" Does both battery(s) pos B+ and neg B- float with no reference to the metal chassis of any of the audio equipment that is connected to the batteries?"

Yessir.

" I am having trouble seeing the loop, closed circuit, to mother earth ground and back to the source, the batteries."

That’s because there is no loop. Have a look at New Page 3 (auralthrillsaudio.com)

Note : It’s not my design (obviously) so I don’t have a dog in the race as to the theory and tech behind the cables and therefore have no interest in debating them. After many many hours of listening and comparing, I found the cables do indeed sound better when connected to ground.

For batteries, I use these guys. Power Station – EcoFlow . Mainly for aestetics, but it simplifies things a lot as well. I can leverage the 110AC out as awell as 5 and 12 v DC outs. When I charge I simply plug them into the wall socket. Easy peasy.

I’d really appreciate anyone that can give me pointers on establishing a completely separate "mother earth ground". Engaging in debate, not so much

Thanks

Bauer uses a Liebherr track and cab, from there on it is ALL Bauer.
They can drill a 3 foot hole in solid granite or basite to what ever depth they can pull out of.. over 100 feet. It’s never a problem drilling the hole its clearing the hole and being able to recover your tooling. 1-5 million dollar rigs.

It wasn’t my forte, but it was the parent company of Klemm
and I had to work on quite a few threw the years.. I was a pretty well known for hydraulics troubleshooting. So concrete pumpers too. Putz and Schwing pump rigs..

Multi pump units, confluence for speed and flow.. and remote.. Pretty serious stuff amigo!.. CANN bus OBD2 + power trains with the new 200k regen engines.. They SUCK.. nothing but problems.. What a F%$#ing mess.

Glad I’m done.. LOL I loved chipping grout to get to 50 30mm nuts and take two days cutting those off with an air ARC. Noisy ba$terd.
To lift a 15 ton cab off a track mount on the side of a mountain at 11,000 feet. I really miss that..

A guys hard hat came off and rolled down the hill an knock out an A HOLE foreman who had his hard hat OFF. The only good thing about the job other than being finished. He got fired, for a safety violation. :-) GOD does smile on me.. he really does.

He yell right up till the time he got knocked out, then he SHUT UP..

Lets say he was well GROUNDED for the purpose of the thread.

Sorry OP, hands are feeling exceptional today, rare..

Marine electrical is two thing, explosion proof, and dedicated - (not really a ground it a completion of the circuit) for every circuit and a star (collection point) for the - DCV battery.
Fuses are again in explosion proof plastics and a second cover in the event of a frag. Most electricians know nothing about DC other than they don’t like it and call it "LO VOLTAGE".

There is no ground in a DC circuit, there is completion of the circuit. They have never used chassis ground unless there was computer involved. The chassis is common it’s not a ground. You can dissipate a static discharge through a common chassis (aircraft) but it is not going to an EARTHEN ground.

I’d keep a separate ground several feet away from a pole ground.. WAY AWAY.. That for overvoltage. PERIOD.

You don’t want to mix them up..

My brother was the BA for the Local IBEW 302. He always came and got his little brother for automotive wiring.. LOL. Great guy.. "Stone face"

Wait till you get bit with 20 12 volt batteries at 12 volts. DEAD! Your DEAD.. a kezillion amps.. no way to let go.. DEAD... Wile E Coyote scene. No holes in you work boot.. and surely no water.. LOL
