Battery "Isolator

[Ken H.]

A neighbor's grandson and his wife are visiting , from Washington state,
with the Mercedes van they're fitting out for full-timing. They're got it
barely liveable with only 12 VDC wiring completed. On the way here, they
had smoke, sparks, flames, and the fire department near Phoenix. The
"isolator" was sparking and the lead from the two 220A AGM batteries 20
feet away melted almost in two inside a wall. I won't go into the faulty
design decisions that allowed that to happen, like the absence of CB's, but
want to ask for ideas:

This is the "isolator" (really a combiner) which first alerted him to a
problem by emitting sparks:

amzn.to/2KUzWHM
or
https://www.amazon.com/dp/B00WTAFR5W?tag=amz-mkt-chr-us-20&ascsubtag=1ba00-01000-org00-win10-other-nomod-us000-pcomp-feature-scomp-wm-5&ref=aa_scomp

Since he threw the destroyed "isolator" away, I can't examine it for clues
as to the cause of the problem. Does anyone have any experience with this
device? I can only assume that it somehow shorted to ground internally, but
I'm skeptical about that...

I'll try to help him correct his design decisions and will even offer him a
Yandina 160A relay to connect as a "manual combiner/boost switch", but the
linked "isolator" seems like a good buy -- unless its prone to such
failures.

Any input appreciated; the young couple's going to be around for a while to
use my shop and service rack to do more work on their rig.

Ken,

It is very lucky for them to have you as a resource. I will leave it to you to decide whether you are going to unroll one of Alan's diagrams and show
him where GM put the breaker 40+ years ago.

Keyline does not have the install instructions available on line, but looks sort of like another device that I saw. I didn't like it very much either
and for much the same reason. There is no insulating terminal cover. It is also impossible to inspect those terminals when the unit is installed.
If the fasteners creep and that allows them back off due to vibration or thermal cycling, either the nut or the cable terminal can contact the
mounting surface. As that is expected to also be the vehicle ground, this cannot end well.

Ken, please look where the device was mounted and see if there are witness marks of the cable contacting that surface.

Car audio places have big fuses and carriers that could be installed.

Stay healthy

Considering the main BAT out wire on our Delcotron is 10 Ga or there abouts, I’m guessing the newer van might have 8ga for that wire. Why such
karge leads on the combiner? The picture seems to show about a 2ga wire set. Whereas Yandina uses a 12ga fixed length lead set and smaller relay
where the lead set limits current through the relay, here the protection must be in the box itself. . So here the relay in a fault situation has to
carry massive Amps. The Voltage “should” drop enough to open the relay but trying to open contactors in that situation is a lot like welding.
Perhaps a bad battery or short on either side of the system started the situation.

The expected visit to my shop for today just got delayed until next week,
so I won't have any more input until then.

However, I have learned one sorta strange fact during this, from
researching the "Isolator". From all indications, our little community is
the only one maintaining the "Isolator" vs "Combiner" syntax. In fact, the
terms "Isolator", "Separator", and "Combiner" are used essentially
interchangeably on the web.

Gee, it is hard to be correct, when those all around us are wrong.
There is one part that I use on my wireless remote air ride system
that the manufacturer insists upon calling it by the term "manifold". Last
time I checked, a manifold attached to a cylinder head and gasses flow
through them either into or out of the engine.
The wireless thing is a combination wireless modem, valve body, and
air pressure regulator. Sure not a manifold. But, try telling the
manufacturer that.

Ken,

I have run into this also and it is infuriating to try to answer a specific question and then find out the the terms were reversed, mashed or
misused.
I guess words no longer have actual meanings....
A battery charger is not a converter either, and it sure isn't and inverter.
You can't "Boondock" at Walmart. (Boondock has become any type of dry camping or maybe even with electric.)
The "Holding" tank is not for potable water.
A WiFi booster won't help your cell phone coverage.

If I sit here a little longer, I know I can come up with more.....

“Won’t turn over” means won’t crank to me. To many it seems to mean “won’t fire and run”. Confusing.
Also 12V. I metered my battery and it’s 12V so it’s good and full charged. No sir, at 12.0V your battery is almost fully discharged. 12.66
would be charged at room temp.
So now maybe this thing is an isolator? But no heat sink?

Ken, when ever that thing gets there test the 2 AGM batteries to make sure they are good. This past summer i had 2 AGM's in my coach (one for engine,
one for house) and the one for engine, although it worked fine delivering power to keep the engine running it just didnt have enough CCA to start it.
Now as the summer went on i noticed one day that the battery was getting really hot when charging but no other failure signs were present. Luckly i
caught it and swapped it out for a flooded battery and no problem since.

One thing AGMs do not tolerate is being over heated and once that happens your basically in trouble....possibly that is what happened here.

(On the vehicles we build a computer controlled voltage regulator is used that is programmed to adjust the charge rate based on battery temp and
current.)

Rich,

Thanks for the advice. Having no experience with AGM's, I need all the
information I can get if I'm to be of any help to this young couple. One
thing they told me, that really bothers me, is that they "...have 2 AGM's
in the rear...". I presume they're in parallel and probably with no
protection. Are the hazards of paralleled AGM's the same as with regular
lead-acid?

When I briefly looked at the rear-mounted 12VDC house wiring, the
connection of the main cable, which "melted down" at a 12" diameter coil
behind a wall panel (ripped out by the fire department), had been severely
overheated. In order to heat that 5/16" stud to blue/black, it had to be
very severely overloaded, and probably not properly tightened. It's still
unknown to me how the overload occurred

As of last fall, I had fit AGM house and main engine banks in an half dozen owners yachts. From my study and experience, there is little real
difference between AGM and flooded L/A batteries. They can accept more charge current and so be returned to full charge somewhat faster because they
don't have to circulate the electrolyte. I do not yet have enough experience to say that they are less likely to have an explosion when connected in
parallel. I would guess (hope so) because there is not the pool of liquid to boil off.

I am eager to hear what you find when you get to investigate the incident. It is a shame that the subject combiner was pitched.

Happy New Year and Stay Healthy

Point taken, but even the manufacturers call that strange blend of battery charger and power supply a “Power Converter”.

Check it at http://www.Progressivedyn.com

Kind of like “motor”. It’s an engine, but, you know that.

Well, a manifold is anything that connects one to many or many to one to deliver air, liquid or gas ( or maybe solids?).
Your engine has two manifolds, the intake manifold and the exhaust manifold.
Your gas furnace has a manifold to deliver the gas to the burner, compressed air systems frequently have distribution manifolds.
So I think you are wrong

Keith, I respect your opinion, and you are absolutely are entitled to it.
But, electronic modems, transmitters and receivers, valves, etc. are
definitely NOT parts of a manifold. But, the manufacturer is allowed
"poetic license" to call his proprietary components by any name that they
choose. Wrong or right? Who knows. Last time I checked, my name wasn't
Webster or Merriam.
What you guys call "mudbugs" we call crayfish, while others call them
crawdads. Still the same critter.
