gentlemen
I am attempting to input an automotive cd player into
the flightcom 403 intercom.
I have a couple wires marked as music input on the 403
But I connected them to the left and right speaker
output of the cd player and its not right.
The cd will play thru the system but I have no volume
and the music is not clear.
Should I be looking for a different connection from
the cd player rather than the speaker output.
Or any other comments
All appreciated
cary rhodes

I have a spot where I have to cross over a main power cable with a com

No, there is no practical instrumentation you can
put on the panel that will give you a measure
of battery capacity.
>Assume that the battery is no more than one year old.
Time in service is a VERY rough gage of capacity. Unless
a battery has suffered severe abuse (run down and stored dead)
it can be counted on to have a substantial portion of the capacity
it had when installed new.
The only measure of capacity is to conduct an actual
measurement of stored energy. A dime-store hardware
test fixture is described in:
http://www.aeroelectric.com/articles/battest.pdf
The easiest thing to do is buy cheap and replace often
and you don't have to worry about it.

Try turning the Aux Alternator switch ON before turning
the Battery Master switch ON and see if it pops. Wiring
it backwards shouldn't cause the crowbar module to open
the breaker but the ov module may have slipped voltage
calibration. Do you have a bench power supply that's
adjustable over a range of 12-18v?

If you're putting this breakers on the b-lead of a 60A alternator,
it's too small. See first column of page 7 in this
document:
http://www.aeroelectric.com/articles/Rev9/ch17-9.pdf
If this is a b-lead breaker, consider get it out of the cockpit
and onto the firewall as an ANL60 current limiter (fat fuse)
as offered here (about half-way down the page).

If you have one, you want an AUX out, preamp out, or line out - all names for basically
the same thing, a line-level output. The speaker outputs come out of
power amplifiers designed to drive the signal into 4-ohm speaker loads. They can,
in fact, even damage the inputs to your intercom if the intercom isn't protected
against this sort of thing.
If you don't have preamp or similar outputs from your CD player, then go to a car
stereo installation shop. They sell devices designed to hook head units without
preamp outputs into aftermarket amplifiers. Basically, you hook your speaker
outputs into these things and they provide line-level outputs. They aren't
perfect - every device you add in the chain will cause some loss of signal quality
- but they do the job if that's what you need.
Regards,
Chad

Cary,
Look for an "aux out" or something similar on your CD player. Using the
speaker output will put way more power into your intercom then it was
designed for. If you have the specs for the intercom you might also check
to see what the max input voltage for music is and then check to see that
the output voltage of the aux output of the CD player doesn't exceed it.
Bill

| Subject: | Wiring Internally regulated, OV protected alternators |
....
--> AeroElectric-List message posted by: Jim Sower <canarder@frontiernet.net>
Bob,
I had a question that might have fallen through the cracks on our most helpful
back-and-forth on wiring alternators.
If I have an OV protected Internally Regulated alternator such as I described
with "F" and "I" terminals, and since the B+ is switched at the relay and OV
protected, is there any compelling reason why I can't simply install a little
jumper from B+ to "F", and through your suggested 150-ohm 2-W resistor to "I"?
It would simplify wiring some.
I will remove the capacitors from the alternator frame to B+ since they were to
stop brush noise and you pointed out that brush noise is a non-problem.
Thanks ... Jim S.

| Subject: | Possible leak through filter diode ? |
--> AeroElectric-List message posted by: "Gilles.Thesee" <Gilles.Thesee@ac-grenoble.fr>
Hi Bob and all,
A sudden concern came to my mind.
After exchanging some messages on this list I wired a cigar lighter direct
to the main battery bus. Of course there is a fuse. I put a small filter as
per the Aeroelectric book, with a Zener diode and a capacitor across the
leads.
My question is, COULD a leak through the Zener diode drain the battery ?
Or is this leak current so small as not to be a threat ?
Thanks,
Gilles

The zener should not conduct at any normal operating voltage and
is not a load-threat to your battery in a parked airplane.

I answered that . . . I'd rather you didn't do this given that
I don't know the behavior of your particular alternator's regulator
circuit.

Capacitors were useful on the output terminal of GENERATORS for
reduction of brush noise but serve no purpose in this regard on
alternators.

Bob and I conversed off list and he wanted me to post to the list for some input
from the group. The following is my proposed panel. Much of it was selected
to minimize the wiring time. Wiring and everything associated has me paranoid.
I think I'd rather have a root canal. Your input is greatly appreciated.
Equipment list as follows:
Garmin 340 audio panel
Garmin 430 GPS/Comm
Garmin 106A CDI
Garmin 330S transponder
UPS SL 40 Comm
Trutrak 2 axis AP (not sure which one yet)
Dynon EFIS
ACS2002 engine monitor
Approach systems wiring hub
EXP buss switch panel.
Some sort of CD player
Back up stuff will be 2.25" airspeed, altimeter, and T&B.
Fire away, Nomex on!! Thanks in advance.
