Polishing with a bit of 180 grit sandpaper or a pencil eraser would be a
better prep for crimping and soldering. What is 1/10,00 of an inch of
pure anything supposed to do for you? The copper is still showing
through, so you haven't sealed it from environmental oxygen. Soldering
is an exercise is dissolving some lead/tin alloy in with the surface of
copper. Your 1/10,000" layer of silver just becomes part of the mix. A
little flux on the copper before the soldering is going to do more for
you and an permeable layer of silver dust.

Hi Ernest
Thx. for the reply

>>

"The copper is still showing through, so you haven't sealed it from
environmental oxygen."
The pictures from the I-Phone did not do a very good job taking picture of
a shiny object. There is no copper showing through, the silver in fact
completely covered the copper.
Copper in fact does corrode into a non conductive surface. Silver does not
oxidize but will react with sulfides in the air and form silver sulfide,
which is a bit unsightly, but none the less conductive.
Why are terminals, terminal blocks and terminal block hardware plated?
Are you saying that we would be just as well off using lets say ring
terminals with no plating, just pure copper and sand contact area before
application with 180 grit sandpaper, and the 180 grit sand marks are going
to go away because you are going to tighten and mush both surfaces
together with no chance that there are areas where the sand marks will
allow corrosion to occur and creep into airtight sealed areas?? It's just
a matter it's a greater amount of work to sand each contact area?
Trying to understand.
Sincerely
Ron Parigoris

I think the simplest program to use for diagramming might be Microsoft's
Visio, but it's not cheap.
I have been using CAD full-time for over 25 years and I know I could sketch
out a diagram faster with pencil and paper, but I would use CAD to make it
legible and presentable, just like Bob N. does.

| Subject: | Re: SD-8 self excitation |
Sorry, was not on the planet for a month, and missed this!
After my own investigation, it seems as though the recently produced
regulators are still in need of the work around. I started the
engine, and engaged the alternator with the battery offline, and
nothing happened. Engaged the battery momentarily, and the alternator
supplied the whole electrical system with a sweet 14V from that point
on, until the engine was stopped. Again, once the engine was started
again the alternator circuit didn't supply power until the battery
gave it a jolt.
Just to make sure, once the alternator is delivering power, I can
remove the battery from the circuit and it continues delivering power
quite happily. It's only a once-off initialisation that's needed to
get the regulator up and running...
Thanks
Etienne

I have to admit that Vern is right. ExpressPCB is stone simple and furthermore
send nets and components onto the ExpressPCB PCB program (if you use it for that).
I don't think it can be used to down load Z-Diagrams or components, but it is still
very simple to learn and very powerful. See:

| Subject: | Calculating wire guage requirements |
A simple question .... On a composite aircraft, with aft battery and a long
run to a panel ground in front how much of the wire length is considered in
determining wire size? Is it only the length from the buss to the unit to
the ground point or must the length of the #2 welding wire from the ground
point back to the battery be included in the calculation? If I've learned
anything from the Connection and this List, I think that the #2 length
would be excluded due to its much greater capacity. Right or wrong?

Believe it or not, your iPhone most likely did a better job of showing
the true state of affairs than your eyes 8*) Our eyes tend to spread
shiny and make it appear to cover more area than it actually does. It's
hard to "see through" the shiny. That's why we test the silver coat on
our fabric with a light bulb.
Make a sample of copper scrap, coated halfway along the length. Hang it
in your shower or other hot/humid environment for a few months. If
there is anything more than minor differences in the corrosion rate,
I'll send you a new dollar.

Which would be a great argument for silver plating. Real silver
plating. Where ALL the copper is protected, not just enough to fool the
human eye into thinking that it is all covered.

It is cheap to have a machine do the plating in an industrial setting.
Much cheaper than even a few returned items due to a Chinese subsistence
day-laborers failing to tighten a screw properly. Much cheaper than
having to have the day-laborer clean the contacts after they sat in a
humid warehouse for several years. It is also prettier, and makes
storage and future changes less problematic (ie, you don't have to clean
the terminals every time you move wires around).
Still, there is a big difference between a process controlled plating
process, and wiping on some silver dust with a damp cloth. There is a
lot of energy pumped into a plating machine to insure that the nickel is
properly bonded to the copper. Where is the energy to make sure the
silver dust bonds?

Yes. But it is no more work than wiping on the magic potion. Copper is
soft, and mushes easily. Under the entire ring terminal, you only need
as much surface area to be in intimate contact as the cross-sectional
area of the wire to maintain the same line resistance. Remove a few
properly torqued screw from plain copper ring terminals and see how much
deformation there is. Hint: there' s a LOT. Also note how the area
under the fastener is bright and shiny, while the outside edges are
gunky and corroded. My rotary engine uses copper seals under banjo
fittings, because it will deform and seal up air tight. Lycoming spark
plugs use a copper washer for the same reason. No silver dust needed.
Make no mistake. I don't think the silver dust will do any harm. But
from my experience, I can't believe that it is more than a tedious
exercise with no payback.

Bill...
It sounds like you are trying to open the symbols library and view the
files from Windows...they should be accessed from within ExpressSCH,
after you've started the program.
However, if you really want to click on a symbol and THEN have that
click open the program to view the symbol, you can set Windows Explorer
up to do that through the Tools>Folder Options>File Types setting. Pick
the file extension, and then assign the program that you want to work
with it. Windows will then open the program first, then load the symbol.
Now if you are using Vista (I don't), then ignore all of the above...it
may be selectable as I stated, or may not.
