| Subject: | Re: Redundant Power switching |
Dick and Joe, thanks for your input.
Dick, I will have two switches. The plan is to use the DPST to switch legs of 6-7A
and 2A. One switch is a Honeywell AML 34, rated at 125v/15a @ 60% power factor.
The back-up is a Honeywell AML 31, 125v/10a @ 60% In a similar chart for
another switch, Honeywell specifies "Resistive", along with % power factor so
I'm assuming that the %power factor is for inductive loads. The 6-7 A load is
for electronic fuel injectors which I believe are solenoids and hence, inductive
loads.
Joe, I didn't quite follow how the loads on the switch legs are additive. Each
pole/switch is separate from the other in the switch and are fed from fuses on
separate buses.

I would appreciate anyone's comments on my electrical schematic.
I'm unsure about the placement of the over voltage module for the Ground Power
jack. I used a single post continuous duty contactor which I had and it necessitated
some changes in Bob's Z-31 drawing.
Thanks
John

For some reason I can only see page two of the PDF - cutting off some
portion to the left of the main battery bus on your schematic. Page one
is blank.

I'm having trouble getting a reading from Klaus's Plasma III box (RPM
pulse) to my Dynon. Either Klaus or Dynon is telling me fish stories.
I'm looking for a gadget that fits as a pass through to a DB15 connector
and has stubs or leads off the side so it would allow me to test values
passing through DB15 the connector.
This sounds reasonable but I have no idea if such things exist?
Any ideas on where I might find something like this?
If they do exist, what are they called?
Thanks,
Glenn

How about a jumper cable where you crimp two wires to each pin. Then you
could take the extra wires out to a test plug.

The complete schematic is on page 1.
Disregard page 2.
There's some glitch in my TurboCad v. 11 that makes a truncated page 2 when saving
files as .pdf

Google 'inline db15 breakout connector'.
1st one I hit on was:
http://www.winfordeng.com/products/brk15mf.php
If you do a bit more digging (try Black Box), you can probably find one
that is just 3 dB connectors back to back to side, allowing insertion
in-line with existing cables/chassis and giving you probe access on the
3rd connector

Thanks Ron,
Yeah, that's a pain 'cause Klaus has those wires shrunk in there tighter
than you know what...
Today I learned something from one of our subscribers. It's called a
Break Out Box.

Wow,
If I buy that I'll put Bob out of business. I don't what to go into the
business, just get an lousy RPM reading on my Dynon. I'll dig for either
used or a harbor freight something.

http://www.bipom.com/products/us/3376564.html (which seems to be the
same as above)
These used to be readily available for troubleshooting RS232 cables but
I cannot seem to find any but those above.
As someone else mentioned, you can make your own with either solder or
crimp DB15 connectors by just including a second wire connected to each
DB15 interconnect wire.

Goodie!
Another person told me they'd expect noise if the P-leads are in the same bundle
to the panel. That's how I've got them. But I don't have any audio system hooked
up yet. Those wires would cross the P-leads or at a right angle.

Yeah, I've got a fist full of those that have proven
handy in my business for over 50 years. When you're
working with low current D-sub signals, here's a little
trick . . .
http://aeroelectric.com/Pictures/Tools/Test_Equipment/Quck_n_Dirty_Breakout.jpg
A piece of ribbon cable and some munch-on connectors
can be assemble in a variety of useful combinations.
A M-F patch cable of appropriate length can be
'enhanced' with a female connector either between the
ends . . . or on a "flying tail". Last time I built
one of these was to look at some signals on a black-box
buried about 3' away from anyplace I could get access
to in flight.
I took a 4' piece of ribbon cable and munched the
M-F pair on one end about 4" apart. On the other
end, I put a female connector to serve as an array
of tiny "pin jacks" where ir proved easy to eavesdrop
on what was happening at the other end of the cable.
If I were in better shape for being unpacked and sorted
out, I could send you the break-out adapter shown in
the picture. If you can't get ribbon cable and connectors
locally, a friend of mine in Wichita could assemble one
for you from inventory (Lloyd's Electronics) and mail
it to you. The whole thing goes together in about 5 minutes
for about five dollars.
