Okay, WHY heavy duty? This switch normally carries
less than 5A for the alternator field and 1A for
the battery contactor. Since you're not attempting
to eliminate the battery contactor with a manual
switch, I'm mystified by the notion that trading
out the two pole master for a single pole device
is a good thing to do . . .
<snip>
Ok, so if I'm reading you right, since the battery lead on the alt and
the field lead are both connected to the main power bus, the residual
magnetism in the alternator could cause it to produce some bias
(voltage) that will keep the field coil working, which creates more bias
causing it to continue to work. Did I get that right?
Yes, that is the essence of "self excitation" . . . generators
did it nicely, alternators often do not come on line by themselves
but will run without a battery once they get stood up.
I wonder what happened to my attachment, I got it. Oh well, you can see
it here:
http://forum.matronics.com/viewtopic.php?t=67973
Anyway, no I'm not looking to replace the battery contactor.
Okay. That leads me to inquire as to the design
goals for departure from the legacy control philosophy
for a DC power master switch in aircraft.
No, I just like the switch (it's a push/pull), and it just happens to be
high current, I'll still use the contactor.
If it's just a style-thing, I'll suggest you reconsider
and go with Z-11 (or other architecture) as published.

field
Schu,
In the past, wanting to test the alternator on my car, I disconnected the battery
while the engine was running. The engine kept running, which proved to me
that the alternator was working OK.
As for your proposed circuit, it looks like it will work OK. The only issue
that I see is that a hot wire will be brought into the cockpit with no way to
shut it off. That wire should be double insulated and protected with a fuse near
the battery. You could use a relay near the battery to eliminate the hot
wire into the cockpit. That introduces another failure point, which is OK as
long as you have a backup plan.
Can you manually trip that 5amp breaker? Is there some failure mode where it
is desired to shut off the alternator without shutting off the master contactor?

Lincoln,
The dynamo relay has a missing diode from the N.O. terminal to the coil. This
diode allows the relay to be energized from the dynamo power even if the battery
and main alternator are completely dead. If you do not want to use this
diode, then the other diode that connects to the COM terminal is not needed either,
although it does not hurt anything. Either both diodes should be used,
or none at all. Using two diodes allows the dynamo relay to be powered by two
separate sources without connecting those two sources together until the dynamo
relay contacts are closed.

Hey, with a Moxie can front and center, they've got my business! Very
cool! I can't count the number of cases of Moxie I've gone through
during my build. I used to bring back 3-4 cases when coming home to
visit in Maine when I lived in NC.
Now that I've here in Maine, it is much easier to get... :-) Looks
like this company is not too far up the road from me, so I'll have to
stop by and pick up some when I head up that way.
Thanks!

Hi Dick,
Either you are getting a bit confused or you
are looking at different websites than I am. I have ordered a pair (2)
Folding cup holders through Scottlandyardspares.com for a grand total of
$11.50 postage paid.
When I looked at the ebay site I found the
same thing for $9.95 + $5.95 shipping, or $14.99 with free shipping.
Am I missing something??

Yes! These will be wired directly to my endurance bus. My endurance
increases with one good cup of coffee, but, decreases rapidly with each
succeeding cup.

Hi group. New member here. I just bought the Revision 11 book at a
reduced price. I am building a simple (electrically) airplane and had
hoped to use the diagram Z-11 as a basis for design. Alas it is not in
the book. The first drawing in the Z section is on the back of page
Z11 but it is Z-12 for a dual alternator. What gives? I understood
that I could upgrade my book on line with the newer stuff and maybe the
drawing is available there, but I can't find that link.
