Hi Jeff,
I've got 40105 pumps in my wings and two on the firewall. Seldom have
more than two going at any time, but I have a 7.5 amp fuse to operate
all four. I've never blown
a pump fuse. They probably only draw an amp, but a little more fuse here
will not harm anything.

I'm just getting into the electrical stuff on my plane. So please tell me if my

This seems like a place for multiple fuses if there ever was one. If you blow a
fuse you loose all 4 where the problem might just be on one pump.

Jeff, remember that the fuse/breaker is there to
protect the wiring not the load. Size you breaker
according to the size of wire. I forget the exact
numbers but 18 ga wire is supposed to be able to
support something like a total of 10A.

Travel and the Zodiac XL - my XL isn't flying but I thought I'd stick my oar into
the discussion regarding the practicality of the aircraft for travel.
I owned a C172 for 23 years and a 182 for 7. I have visited every state except
HI, LA & MS. Also been to Alaska and the Bahamas. Much of that travel was in
the 172 with only one pax. I got the 182 when my family got older but now my
kids are grown and no longer travel with us. I am a big fan of Cessna aircraft,
have thousands of hours in them and yet I chose to sell my Cessna and build
an XL....
True, the XL has some useful load limitations but by my estimates it should be
faster than the 172 and at todays gas prices 5 gph sure beats the 8 or 13 gph
I burned with the Cessnas. I'm willing to put up with the XL's limitations in
order to be able to travel affordably. Like many other retirees, I made the
choice to downsize rather than give up entirely on the activities I enjoy. All
in all, I think it has been a good decision but time will tell.

Subject: | Re: Facet Fuel pump amperage |
I have my fuel pumps wired to my ignition circuit (I don't have
magnetos). My ignition switch is fed directly from the battery through a
30 Amp fuse, bypassing the master switch. The ignition switch feeds a
coil selector switch, a pump selector switch and the engine instruments.
Each pump and each ignition coil is then fed from its selector switch
through its own 5 Amp breaker. If a breaker pops, I switch to the
backup. I don't have an engine driven pump so the electric pumps are
essential. My "run-up" consists of checking that the both pumps and both
coils will function.
If I have to shut down the electrical system in flight for any reason,
the engine can continue to operate after the master is shut down for as
long as the battery holds up. It's true that if one of the three
switches fail, the engine will probably quit, but switches don't
generally fail unless they are being switched and I don't normally
switch any of these in flight. This was a relatively simple way of
getting some redundancy in the system. If the 30 Amp fuse blows, well,
then it's time to land.

Hi Gig,
I guess you could go either way. I would expect things to go without
blowing a fuse on fuel pumps for a very long time. If it does blow
and you can't replace the fuse in flight that just means you must
depend on the mechanical fuel pump on your engine for the remainder
of that flight.
If you have a plane that depends on a working electric fuel pump to
keep the engine going then perhaps separate fuses would be in order.

never wanted to travel there in the summer which was the only time I could

Hi, All,
I am in a bit of a dilemma. I need a three inch glass
for my air speed indicator. I could easily get one from the local clock
shop, but the glass for our steam gages needs to be polarized. Might one
of you fine folk out there have one for sale? I can get one from White
Industries, but I have to buy the gage to go with it for much more than
the glass is worth.
Help!

Kinda like the circuit breaker in the house is there to protect the

As an old electrical engineer, there is a rule of thumb that says you should
fuse at three times the normal circuit load. That pretty well ensures that
the fuse will not blow under normal (and start-up) load but will if a short
develops in the circuit. I agree that there should be a separate fuse for
each pump.

I use three small Harbor Freight furniture dollies. Place one under each wheel.
In this configuration the plane can be moved in any direction inside the hangar.
If you use just one under the front wheel it would lower the tail and be
a lot more mobile as well. You can get three dollies for about twenty five dollars.

Yep, pretty much. I can't think of one single way to work around not having the
center spar and because the center spar is matched to the wing spars they can't
just pull one out inventory. You might get lucky though and they might have
a spar set made up that you can talk them out of. I'd call.
This is one of the reasons when anyone asks here what order to build in I always
say Tail, wings, fuselage.

Actually Phil, the extra fuse at the pump is not
really needed. The purpose of the internal fuse in
your houshold appliance is to prevent it from catching
fire if it melts down. Remember, the 15A breaker on
your house panel is sized for the 14/2 cable in your
walls and the internal fuse is sized for the 22ga
wiring inside your TV, etc. Not likely an issue with
the plane. It is a common misconception that fuses
are to protect "gizmos" The are not. They are there
to disconnect the power when the "gizmo" melt down.
Of a bigger concern might be putting each of the pumps
on a different circuit. Then if you were to loose one
pump due to a chafed wire or someting, you would still
be able to run the other. Designing low wing fuel
systems however, is beyond my expirience as I have
gravity feeding mine.

Subject: | Facet Fuel pump amperage |
Terry,
I overstated the importance of the 30 AMP fuse. It is located
between the battery contractor and the main fuse block. The 30 AMP fuse is
not in the path from the battery to the starter. The starter pulls an
amazing amount of amperage, but only for a few seconds in most cases! But
that fuse does protect everything that draws its power from the main fuse
block including the avionics fuse block. This design is stolen from flying
601s with 3300s up front and is, or used to be, recommended by Jabiru USA.
The Jabiru 3300 installation manual includes a suggested wiring diagram that
includes the 30 Amp fuse on Page 10. My electrical system is a combination
of Jabiru instructions and AeroElectric advice tempered with real life
experience from some other very helpful builders and some of my own "common
sense". Of course Jabiru never imagined a fuel system like mine in any of
their aircraft. Anyway, thanks for the comments. I'm Okay with a larger
amperage fuse now that I find 5 AMP fuses are common for each fuel pump
circuit. That is what I wanted. It seems to me that there is more involved
than just the fact that the fuses are there to protect the wires. The
maximum electrical load is pretty important too. Evidently is common to
have fuses that blow at about three times the expected normal load for each
circuit. That is what I didn't know.
Thanks to everyone that responded to my question.
Time to go pick out a fabric for my seat cushions!

Subject: RE: Zenith-List: Facet Fuel pump amperage
Interesting approach, Jeff.
If I understand you correctly, you are concerned that a momentary, short
circuit load on, e.g., a fuel pump power lead might blow your main system
fuse.
I'm just a reader of the aeroelectric connection, and most of what I know
about airplane electric systems comes from there. And, God knows, I don't
understand all that I've read. So, take this with that in mind.
I haven't seen your schematic, so I'm not sure what the function is of the
30 amp fuse that "protects the entire electric system." I know that the
Jabiru 3300 alternator is rated at 20 amps. That says to me that the steady
state load on the electrical system should be less than 20 amps (so there
are some amps left over to recharge the battery after starting). A transient
load can be much greater than 20 without compromising the system--what does
your starter draw? More than 30 amps, I'd guess.
So, if the 30 amp fuse is designed to protect the cable from the battery to
the main bus, you might consider a larger cable. Then you don't have to
worry about blowing the 30 amp fuse. If you're happy with 30-amp capacity,
you might consider using some sort of slow-blow 30-amp fuse so that a
momentary 5 amp overload on some circuit would not blow the main fuse.
(Something like the LITTELFUSE JCASE HIGH AMP FUSE, PINK 30 AMP (JCAS30BP))
The fuse-to-protect-the-wiring approach makes sense to me. Other approaches
might work for you. But I think that the last thing I'd want in my airplane
is a fuse to the fuel pump that is operating right at the limit of its
capacity.

That is if you are talking about the jigs that reference the spar to the
rear spar.

Jerry,
In the yahoo group "701builders" look in the files section, I think there
is also some gear bending in ch701.com/ch601.com

Hey Michael,
Not to add to your disappointment, but if you are going to order your wing kit
now, I suggest you get your order in as soon as you can. I ordered my wing
kit on Dec 4th. I just got a notice from Shirley that my wing kit is tentatively
scheduled to ship May 7th. The fuselage kit is what I will be needing next
has a 14-16 week lead time. I hope I will be able to place my order as soon
as I can. I have been waiting on this wing kit now for almost 4 months and I'm
going stir-crazy (I feel for yah brother)!!
Regards,

When I called Nick today, I understood him to say that the new kits would
not include them because of the CNC side skins that take the guess work out
of the alignment process. It is also possible that he was talking about
what they are considering, and not yet doing.

Not sure how CNC is going to alleviate the need for the jig. The jig sets
the level of the rear spar to the main spar and the fuse. If your fuselage
is not jigged level, then it alignment is going to be wrong regardless of
the CNC drilling.
My opinion anyway.
I can send you mine when I am done if you dont get any other respondents
that are closer.

Subject: | Facet Fuel pump amperage |
Jeff
As I'm always telling my wife, sounds like it will all work out OK. In case
you haven't seen it, you might take a look at Nuckolls' schematic Z21A
which says it's for a Jabiru 3300 with EFCI. I don't know where the EFCI
came from, but I'm planning on adapting Z21A--when I get that far. It
wasn't in my copy of Aeroelectric Connection, but I got it off Bob's
website. I had a hard time finding it, so I'll post the link, in case
anyone is interested.
