| Subject: | Can Someone PLEASE Help Me Identify This Packard Terminal |
End???
Greetings Knower Of All Things That Dwelleth Behind My Keyboard!!!
I have this terminal end and I cannot seem to find a replacement from Amazon
Aircraft Supply or eBay Airplane Inc.
It is a Packard terminal end that clips into the plastic field wire plug of
the B&C SD-60 Alternator and it is designed for 18 to 20 AWG wire.
All of the plugs I find online have a Square looking socket that are
designed for more heavy gauge wire such as 14 AWG and they all have a square
socket designed for more heavy gauge male spade
This one has a "butt cheek" style socket that is designed for a more thin
male spade.
MANY THANKS!!!

When you say 'thin' do you mean narrower than the typical 1/4" spade
terminal, or literally thinner spade? Here's a link to Sta-Kon's catalog;
they show both 1/4" & .187" width, with most for .032" thickness and a few
for .020" thickness. Various wire sizes available. Scroll through the
'terminal' (quite a ways down for the blade terminals) and 'disconnects'
sections. Your pics look like a typical spade terminal in either 1/4 or
.187 width, but hard to tell with no reference.

Charlie,
THANKS for the information!!!
Nathan from B&C responded to me and he is going to send me a couple.
The part is called a Yazaki 71162090.

Bob,
I like the concept of having the brown-out booster incorporated into the
core diagram.
I think that you have stuff on the endurance bus that would be hard for the
brownout booster to run, In particular, the transponder and the comm radio.
My dual 10-inch screen EFIS consumes 2.8 amps typical, 6.25 amps max. The
Trig mode S transponder is rated at 3 amps typical and 3 amps max. The comm
radio is 0.5 amps typical, 3 amps max.
So I would be happy with a brownout booster that could handle just the EFIS
at 2.8 amps, maybe 6 amps. As your diagram is drawn, were I planning my
electrical system I would think that I needed a brownout booster that could
supply 12.25 amps. That's a big difference.
I think it would be cool to lose the endurance bus and add a light that
comes on when a) the airplane is running on the backup alternator, and b)
the battery is discharging. The light could say something like "DON'T PANIC
BUT IT'S TIME TO SHED SOME LOAD."
Then add a brownout booster bus that has only the equipment on it that
needs to operate correctly during engine start, i.e., the engine
instruments.

I suspect you are looking at spec sheets rather than real numbers. My
Dynon labeled Trig 1090ES transponder runs well below 0.5 amps. My SL-30
Nav-com is also down around 0.2 amps in receive mode. Each of my 10"
screens draws 2.5-3.5 amps depending on whether the backup battery is
charging.
So, I have one switch that turns off one 10" screen and the GTN-650.
That leaves me VHF nav and com, VFR GPS on single 10" screen and
transponder. However, without the GTN-650, the transponder does not
output ADSB data, just mode C. Doesn't bother me, because I am already
in emergency mode if I am load shedding. Or I can leave the GTN-650 on
(3.5 amps) and just turn off the second screen.
All depends on how much load needs to be shed for given situation.

| Subject: | Harbor Freight hydraulic crimper messaroundary |
Well folks,
Will soon need to crimp a number of large AMP terminals to some large wires, and
been playing around with a Harbor Freight hydraulic crimper I had for a while.
I decided to write this report part to contribute, part to solicit thoughts and
feedback.
General notes:
I got my crimper in ~2014, so YMMV (they might've changed the "jaw" dies).
It has hexagonal dies, like the ones in "jaws.jpg" attachment below.
Crimps were made, then hacksawed apart, and cut polished some with a deburring
wheel.
Setup: #8 wire in an AMP lug.
My problem is, I always suspected that these jaw dies are mis-labeled, because
using "nominal" dies does not produce a nice hexagonal crimp. Specifically, it
feels like they are labeled about 4 AWG steps too high (ie, dies labeled 4 AWG
have the hex "hole" that, when closed, is just larger than 8 AWG wire)
And now, we get to the gist of this report.
Test #1. Using jaws labeled for 8 AWG.
Hex opening in them is much smaller than the wire.
Notice how it's this weird pinched, rather than hexagonal, shape (especially well
obvious on the cutaway pic). Also, crimping adds this weird "jog" to the length
of the terminal. Overall though, aside from the strange shape, very good
crimp. Note: on cutaway, the "spots" are dust specs I caught in the pic and noticed
just now :(. They are not crimp defects, like in test #3 below).
Test #2. Using jaws labeled for 6 AWG.
Opening is still smaller than the wire.
Initially, here, I got those "wings" to the crimp, too; but then I turned the crimp
90 degrees and crimped it again, "smashing them in". Notice how mangled up
that whole business is (and without "smashing in" the "wings", it looks just
like the #8 jaws crimp; just with thinner "wings").
Test #2. Using jaws labeled for 4 AWG.
This procuced a nice hex, as expected; and no surprise - the opening on the jaws
is just about the same size as the wire; so with added thickness of material
from the terminal itself it went well.
However, notice on the cutaway you can see some "spots" - those are "cavities",
so makes me thing that it could've been compressed just a tad more.
Overall, my personal thoughts?
Either use nominal or 4 sizes "up" (test #1 or #3). I am probably leaning towards
#1, because, though ugly, that crimp is _definitely_ not gonna rot from the
inside. ...
