I built and tried the other wig wag alternatives using dual 20A continuous
relays with the DIY flasher with the lm555. The problem that I have with
that circuit is that with no lights turned on I have a rhythmic clicking of
the relays going on, so I know that the DIYis producing the proper timing.
But as soon as I apply power to the headlights, the relays start working
with a twitch and are not rhythmic at all. I have the PB310-nd relays from
digi-key. I have used these for my trim. Maybe I should have used z217-nd
automotive relays for the headlights instead. Since I have the wiring done,
this would be my preferred choice, Would either of these ( z217-nd or the
pb310-nd) from digi-key be a replacement for the s704-1 equal?

I do care about Bob... He is a gentleman and a scholar and doesn't need the
headaches of OT garbage innundating this list...
Of course, all those well meaning folks posting OT are the problem, not the
purported virus, or need to register for this or that, yadda, yadda,

My only comment on using mechanical/thermal relays is that you give up the
good feature of the solid state stuff that controls the inrush current on
the initial startup and keeps the filament warm between cycles - drastically
prolonging bulb life...

I have a question about differences between wiring diagrams Z 11 and Z
13. One has a fuselink and the 5 A field circuit breaker between the
main bus and the master switch. The other has the circuit breaker
downstream of the master switch. Does it make any difference?
Also, I'm planning a small 4 to 5 A. H. battery to back up my #2
electronic ignition. I will probably locate it somewhere near the
instrument panel. Would there be a problem grounding it on the
firewall ground, when the main battery is grounded locally in the rear
fuselage?
And the last awe inspiring question of the day is, since there appears
to be a large number of ground wires coming off the back of the
instrument panel, does it make sense to combine them all and just run
one wire to the firewall ground to reduce the size of the wire bundle?
Your mission should you decide to accept it, is to provide some much
needed clarification, and as always your expertise is much appreciated.

Bob, from your description you may need to do three things...
First is that you do not have an adequate series choke and bypass capacitor
on the power leads for the 555 allowing noise to get inside...
The second is that you are getting voltage sag at the 555 due to the inrush
across the filaments... Perhaps a surge capacitor there will help... Any
automobile sound shop will have them... Otherwise, you will need a separate
power lead from the battery to the 555...
And the last is that the transient spike off the relay coil is confusing the
555 and you need a diode across the coil leads and a capacitor to ground
there, also... Although I would have expected it to be a problem even with
the bulbs turned off, however with transients you cannot predict.....

Ok, I saw Bob Archer's VOR antenna (asked where to see it in another post, I
really like it) now I have another question because of this post.
Is it possible that you could create a switch for the BNC connector that
hooks your handheld to the COM antenna so that you could switch between the
COM and the VOR antennas? Of course without lots of signal loss and
noise??? ;) For some reason this just sounds messy.

Which schematic for the 555 flasher are you using? Does
it have a capacitor from pin 5 to ground? I neglected this
important component on several drawings circulating 'round
out there. Not having a 1 uf or so cap from 5 to ground
will produce strange behavior like you've described.

| Subject: | Affordable time-delay |
--> AeroElectric-List message posted by: "Jon Finley" <jon@finleyweb.net>
Hi all,
Looking thru the archives it appears that this topic has been discussed
before but I couldn't find a clear answer.
I am looking for what I think is called an "on-delay timer". My specific
use is to control my low-fuel level light. I have a float type sensor.
The fuel sloshing around causes the light to cycle. I would really like
to install an on-delay timer/relay which requires the input signal to be
"on" for 15 seconds or so (flexible here) before turning on the light.
If the input signal is goes "off" at any point during the countdown, the
timer is reset.
Doing a web search turns up a ton of products. However; not being much
of an electronic geek, I'm not sure which ones would work. So, if
anyone knows of a product that would do this job (and is terribly
expensive) please forward me some info. I have a 12v system and my low
level light is an LED so don't need much capactity on the circuit.
Thanks much!!

Hello Jon,
I sent Mark Phillips (at the possum works) a couple of general purpose time
delay relay modules that I use from time to time in my electronics control
business. They are dip switch settable to do many functions, are dual
voltage (12 & 24) and they cost less than twenty bucks each. I bread boarded
for Mark a configuration that will do just what you are asking. He is using
two tanks with a module controlling the low fuel light for each low fuel
sensor switch. A count down time delay can be set so that the LED is kept
off until the time out is complete. The low fuel sensor must remain in alarm
during the entire count down to turn the LED on. A return to normal signal
from the low fuel sensor cancels the time out. Both sensor alarm input and
completed time delay must be true to turn the light on.
He may see this post and chime in to let you know how they are working out
for him so far.

Bob,
I am using the one called AEC_WW2.pdf found in your last .zip file. The
drawing has a .1uF cap from pin 5 to ground. I will open my case up to
make use that it is to ground. You mentiuone d a 1 uF. Should that be a 1
or a .1 uF cap to ground.

Bob:
I have been studying the Z-14 duel batt duel alt wiring diagram and have a
few questions.
1. Why is the hydraulic pump coming off the main battery contactor as opposed
to the main power bus?
2. Why is there a #2AWG between the main battery contactor and the crossfeed
contactor when there is only a #4 between crossfeed and aux battery
contactor?
3. I am wiring a canard so I have substituted a #2AWG wire for the #4AWG
shown between the main battery contactor and the starter contactor per Z-15.
Same on the return Ground. Is this correct?
4. Should I also connect the two battery negatives with a #2 or is #4 still
ok?
5. Z-15 two different diagrams show the panel ground connected to the #2 AWG
ground wire and the other diagram shows the panel ground connected to the
battery with a #4AWG. Any difference here or is it just preference?
6. The ground strap from engine to firewall ground calls for a braided
strap. Could a #2 welding cable be used here as a substitute?
Thanks Tim

I think I've found one from Grote. It's a school bus electronic
alternating flasher #44730. It's marked 6 lamps/side, 12 volt, SAE
J945,J590, FMVSS 10B or"8". It has 3 .25 faston males which mate to a
generic socket which has 3 8" pigtails for connecting. I haven't tried
it yet but the cost was minimal and available from UAP/NAPA.

I have it on hand. What do you think?

I used hinges on the bottom of the the cown and camlocks on the top.
I used some of the "scrap" that is included with the kit. I think it is
0.032.

about anything .1 or larger will work . . . if you have .1 uf, that's fine.

I purchased one of these gyros from Spruce a couple of months ago. The first
one was using three times the current it should and the RPM was fluctuating.
As the RPM went down the current went up, and the RF noise was
unacceptable.Spruce replaced it with an equally noisy gyro This one
completely wiped out the radio reception in my A/C. I returned this to
Spruce also. Spruce will not issue a credit until the manufacture says I did
not damage there junk gyro.

I used a Tridon EL 12 flasher (aviation aisle at Kragen) and a generic relay which
should be freely available from the same source. This is a type used for
ignition de-activation in auto alarm systems. If you ask the guys at your local
dealership who prep used cars for sale you'll find they throw these away every
day since dealerships don't leave aftermarket alarm systems in used cars.
I have offerings from Potter and Brumfield and Siemans both of which have same
part number.(W4-45F11). No matter the maker, these will all have pins labelled
85,86,87,87a and 30 and a wiring diagram on the side. They are rated 40/30
amp and have a normally closed and a normally open contact.
The circuit works fine although the only issue I've not been able to address is
whether or not it will generate any interference with the intercom or radios.
A VERY cheap experiment to make however.
Good luck.

I suspect there are many but I've not researched and verified
any specific part numbers. Perhaps someone on the list has
taken the time to dig out this information.
