Could we not feed the 504-1 module with power from both the Main and
Essential busses? When the Main Alternator failed the light would come on
because the E Buss switch would be open so power would be lost to both
busses momentarily, and then go off when the E Buss switch is closed
providing 12v again to the 504 module?

Your analysis is correct. The "ALT OFF" light would be
illuminated any time the aux alternator was off . . .
whether due to OV trip -OR- switch in the OFF position.
The light is suggested only for situations where the
SD-8 is the primary alternator like Figure Z-16. Note
that I do not show this light on Figure Z-13 where
the SD-8 is a stand-by alternator and the airplane
is likely to be fitted with voltmeters and/or low-voltage
warning lights.
I will invite you to join us on the AeroElectric List
to continue this and similar discussions. It's useful to
share the information with as many folks as possible.
A further benefit can be realized with membership on
the list. There are lots of technically capable folks
on the list who can offer suggestions too. You can

Subject: | Locking female fast on source needed |
--> AeroElectric-List message posted by: Charlie Kuss <chaztuna@adelphia.net>
Listers,
I recently purchased several Bosch (automotive style) relays and the
related sockets for my RV-8A flap circuit. I purchased these items from
Waytek Wire. Nice folks with brand name stuff at good prices. The sockets
for these relays use a variant of the common 1/4" female fast ons. These
are open barrel, rather than PIDG items. They also have a locking tang, to
secure the connector into the socket body. Anyone familiar with automotive
connectors has seen these.
My question is, I need to find a part number and source for these
connectors designed for 22/18 AWG wire. Waytek has these connectors
for 16/14 AWG, but not for the 22/18 AWG. I know that these things are
actually quite common. I've tried finding them in Allied Electronics paper
catalog and their web site. However, I don't know the manufacturer or the
proper terminology these items are known by. Because of this, I have not
been able to locate what I need. Can anyone help?
The relay sockets and connectors can be seen here:
http://order.waytekwire.com/IMAGES/M37/catalog/216_54
I'm using the #75280 style sockets. These are modular. You can stack them
together. The connectors are part # 31073, also seen on the above web page.

Charlie,
I am also using the waytek wire supplied relays and sockets. I ended
up using the connectors on as small as 22 AWG wire. I used the manual
crimp tool. I soldered the wire after crimping. If you don't want to
solder, then just strip your wire a little longer then double it over
in the connector before crimping. This will make the connector "think"
it has a larger diameter wire inside.

Most European auto dealerships have these in a electrical repair kit, which
was part of their dealership requirement.
If you're not locked in to those particular relays, you might want to find
a dealer and see what they have to offer.
I plan to use GM or Chrysler standard. They are smaller, light, available
at a fair price, and meet what ever electrical requirements you can dream
up. Available, as in stock at auto dealers across the country. That
includes Sockets and Fast-On connectors.

Crimp! If you want to have a disconnect, and it is in the engine
compartment (or somewhere where the temp is somewhat different than at the
data module) use the appropriate connector plug from Omega.
And maybe others can back me up on getting Tracy to go to a crimp pin D-sub
at the EM2 25-pin plug rather than the solder-socket. I found soldering TC
wire to the pins is a real challenge (even needed some additional flux, and
now I worry about corrosion); and soldering those materials doesn't really
form a bond anyway (no eutectic as with copper or silver), just a mechanical
bond.

Availability was one of the reasons I chose these relays. They are the
Bosch units used on all GM, BMW, Volvo, Mercedes Benz and VW autos.
Murphy's law says that stuff breaks a thousand miles from home. I'd hate to
have to stay over night because I couldn't lay hands on a part on a weekend
afternoon. These connectors are used by GM. You can find the relays here
for under $4 each.
http://order.waytekwire.com/IMAGES/M37/catalog/216_52
The auto dealers here (in the USA), don't sell individual electrical
terminals. They sell either complete wiring harness sections or "repair
plugs". I've been in that business for over 20 years. Been there, done that.

The fuse holders are RATED by the manufacturer for up to
30A continuous. I de-rate them for my designs down to 15A
continuous. Do you have any accessories that draw more than
10A continuous?
> Will I be okay running say 30 to 40 amps total? through

Total rating for the 20 slot fuse holder is over 100 amps.
The largest full-up running load I've calculated for an
IFR ship running pitot heat is 27A . . . These fuseholders
are quite adequate to the task.

Any diode rectifier in this package is good for 25A minimum. The
E-bus loads in Figure Z-11 should be under 5A or so . . . if
you have a standby alternator like Z-13, then you can run an
e-bus of 10A continuous. These rectifiers will handle 10A
nicely when bolted to an aluminum surface.

Not really . . . there are some tiny advantages including a slightly
lower voltage drop . . . but the ratings for any single diode
should be most adequate.

The very niftiest method for joing thermocouples is to weld them....
However,
the welders I have seen are all very expensive when doing only a few
connections.
That said, if you need to make a splice in a location where it would be most
convenient to have a service disconnect, then by all means, a dedicated
Omega connector is a good (if bulky option). Even a dsub connector will
join thermocouples adequately. The downside is that these introduce more
failure modes, not to mention expense.
Silver solder is a good option. It is light weight, not particularly
difficult to
accomplish, and is relatively robust.

Female Fastons would be simple. However, in viewing pg. 52 at the link you
gave below, there was a note in the the bottom right hand corner saying
"High capacity and standard relays use connectors 75280, 75281 and 75282 on
page 54." By simply going to the url address line at top of browser and
backing over the last digit (the 2 in page "52") and replacing 2 with 4, it
brought up page 54, which has connector shells - and (drum roll) . . .
female Fastons, if I understand the term correctly. Gives part numbers for
all the stuff.
- Says they are "bright tin plated" which is good - better corrosion
resistance.

Subject: | Simplified Z-13 elec sys- eliminate starter contactor | & PM Alternator switch
--> AeroElectric-List message posted by: "David Carter" <dcarter@datarecall.net>
Gary,
I'm looking at Z-13 as I compose this e-mail.
Alternator Switch issue:
My plan is to eliminate the "field controlled alternator shown to right of
Z-13 and only use a John Deere PM alternator in place of the SD-8 "dynamo"
shown in upper rt corner of Z-13. Now, the OVM (overvoltage module)'s relay
coil is part of an "always hot" battery bus. So, if I eliminate the (aux)
Alternator Off-On switch and just run the wire below the 5amp CB to gnd,
then the relay coils will run down my battery overnight. But, that can be
fixed by re-wiring that coil so it is NOT "always hot" but only gets power
from the PM alternator when it starts turning. (disconnect short wire from
bottom of contactor of OVM relay and re-connect to, e.g., the top of the
filter capacitor - main red output wire from PM alternator's Voltage
Regulator. And connect bottom of "(aux) alt cb") direct to gnd - & elim the
alt sw.) I think that is what you and I really want to do - no switch, no
voltage & current to close the OVM relay until PM alternator is putting out,
and use the OVM's "kill the OVM relay" cb as a switch if needed in an
emergency to stop electrical smoke.
Starter issue:
Again, I'm looking at Z-13 as I write this. There's a 2awg "fat wire" going
from "battery contactor" (a manual switch on your plane & mine) to "starter
contactor". Coils of the "starter contactor" are powered from the "push to
start sw", closing the main/big current contact and current flows to post on
solenoid on starter and a parallet tap goes to actuate the solenoid coil,
which closes and passes main current to the motor.
- I understand you want to eliminate the "starter contactor" and run
the 2awg "fat wire" direct to the "main juice post" on the solenoid, and
eliminate the parallel tap-off from that "same-post-to-the-solenoid-coils" -
rather, run the 20awg wire from push-to-start sw to the "solenoid's coil"
instead of the "starter contactor" which we just eliminated.
- Then if the starter "runs on", we turn off the manual battery switch
to kill power to the motor.
- Now, here are my questions about starters:
____- Is there a particular "name" for the type of starter shown in Z-13?
____- Is there a particular "name" for the type of starter that you would
use instead?
____- Or do we just wire any old starter differently so the solenoid coil's
juice comes from "push to start" and the "main juice" comes straight from
the battery master? (always hot, always protected with a fusible link or
some such)
____- I have lots of e-mails about Sky Tec starters, of which there are two
major different types (PM and not??) Then there are various auto starters
mentioned. So, are there any specific brands and models that you know will
work like you & I want it to?

Subject: | Re: OV protection for PM alternators |
--> AeroElectric-List message posted by: "David Carter" <dcarter@datarecall.net>
Ken,
To do what you suggest, looks feasible to "transplant" the OVM relay,
module, and CB system from its current position in Z-13 to be between one
of the two wires showing between the SD-8 (John Deere in your case and mine)
and the VR. Seems like a fairly simple mod. Or, at least a fusible link
ought to be in that output line between PM Alt & VR so the "always spinning,
always outputting" PM alternator would have no place to "output" to.
A question: Why does it show two wires between the SD-8 and its VR? Will
the John Deere also have two wires, or just one? I think you and I have
Deere schematics but I can't lay my hand on mine (office is packed up for
painting walls).

Read the description of those terminals carefully. The 1/4" females
(#31073) are for 16/14 AWG wire. The ones for 22/18 AWG (# 30073) are only
3/16" wide. They won't fit on the 1/4" terminals of my relays. The 3/16"
terminals are used on the newer "micro" relays. GM and other manufacturers
are switching over to these smaller relays. My experience is that the
failure rate due to overheating of the smaller contact surfaces is much
higher, than for the older relays with 1/4" terminals. I want to stick with
the "tried and true".
These 1/4" female push on connectors are as common as dirt in the
automotive world. I just need to find a part number or a source.

Dang, Charlie. "Devil's in the details", ain't it?
Well, just do like 'lectric Bob and others say - double the 22awg wire over
and crimp away. If doubling doesn't make the wire fat enough, then cut off
a piece of 16 or 18 or 20 awg wire (biggest possible and still fit in with
your 22 awg) and use it as a "shim" to take up the space. If you are short
on the larger wire and have tons of 22awg like me, then cut off as many
pieces as needed to fill the barrel of the faston and crimp away. Heat
shrink should help stabilize the skinny wire coming out of that big faston
barrel - maybe a 1/4" length of "little dia" heat shrink" over the 22 awg,
then longer length of larger dia heat shrink over the barrel and the 22awg
with its 1/4 inch of heat shrink - to stabilize it.
I have a piece of copper braid I cut out of an old battery strap - trimmed
the piece of braid so it is as tall as my battery terminal and is about 1/3
the circumference of my car's battery post. Now, when I put the negative
cable's terminal end over all that, it can be tightened up nicely - post
was too small without the "shim". Same principle for the fast ons.

Subject: | 220 Ohm Resistors? |
--> AeroElectric-List message posted by: "Malcolm Thomson" <mdthomson@attglobal.net>
I believe I have seen that two 220 ohm resistors can be used in
conjunction with an LED to act as a OV light on the B&C LR3s. Can
someone help me with how 220 ohm was determined and why two of them?
Normally, I use a 600 ohm resistor in series with an LED to operate at
13.8V. (drop 12V at 20ma). What am I missing here?

abbreviated resume
Some of the GM relays are also Made by OMRON in Canada. In my 20 years in
that same business I found that all the parts are not in the parts room.
Somewhere (where ever they keep the Special Tools) in each of the
dealerships you have named., is a suit case sized kit filled with, Fast-Ons
of various sizes, sockets, pin pushers, and various crimping pliers. Don't
Go to parts, find the Service Manager and get a Mechanic. Most
Mercedes Benz and BMW electrical are made by Siemens. I tried to point you
to another source but completely left out the word ... Chrysler.
abbreviated resume
You know I STOPPED dead in my tracks in the middle of this reply. Thinking
how many have the hair on the back of their necks standing on end ready to
flame every word I say. I don't offer my view point to anyone unless I'm
standing on pretty firm facts. I've been around airplanes all my life, spent
26 years in the military flying and fixing them. After that I spent 20 years
making a living fixing cars. Porsche, VW, Audi, MB, BMW, Volvo, Saab,
Ferrari, Masseratti and my favorite Chevrolet are some of the makes I worked
on.
What information I offer is given so that someone might, with more ease or
economy, realize our mutual dream of flight. I have already researched this
air plane to some considerable extents. When I see on the list someone
covering the same ground that I already have, I want to lend a helping hand.
I just had to add that in. I feel better.

I am hearing slight alternator noise in my headsets. Sometimes they are garbled
plus transp. doesn't always get through. I feel I need to separate my
com/intercom from the master solenoid and feed off the battery. I have already
installed the noise filter after the master solenoid.
Also the mic key makes the wing leveler turn plus the fuel gauge pegs out. Is
there an extra shielded coax that works with the B and C connectors or should I
pull some off of an other larger coax to double shield?
I have just a "whip antenna" with a metal screen ground plane. Would the aluminum
"Flying W" be better than a dipole flat metal ribbon that "Spruce" advertises?
