| Subject: | Re: Brownout Step Up Converter |
I used the IPS from TCW Tech. It worked fine.
But then I pullen it and installed a backup battery for the HXr. This allows me
to power up the EFIS well before turning on the master or starting the engine
in addition to providing brownout prevention. It also provides an additional
power source for the EFIS should things go really sideways in the electrical
system.
GRT also sells a backup battery (12v only).

Yes, both files of RevB are posted.
The next upgrade to the Z-Figures will probably
'retire' most if not all of the legacy figures
applicable to aircraft engines (lyc, cont). Z101
iterations cover all previous variations on the
theme.

| Subject: | Alternator/Strobe whine |
I could use a little help debugging this problem. A few months ago I
complete a major panel overhaul on my GlaStar basically using Z-12. The
plane came with a B&C L40 alternator with an LR-3 voltage regulator.
There's always been strobe noise in the headset. A couple years ago I
replaced the "old" Whelen strobes with AeroFlash LED strobes and all new
shielded wiring. I still had noise but it wasn't bad.
As part of this overhaul, I added a B&C BC-410H accessory pad alternator
and SB1B-14 standby regulator. Since either alternator can handle the
worst-case load, there's no essential bus. For space reasons I ended up
relocating and almost entirely rewiring the LR-3. I also totally
replaced all the avionics including audio panel, intercom, headset jacks
and all associated wiring.
The problem--the strobe noise is worse. But it's only present when the
primary alternator is on. On just battery or just standby alternator the
system is silent. Any thoughts on how to silence this little demon?
Thanks
--Rick

Thanks Bob,
I downloaded the 101B but my Intellicad says that it was created with an
unsupported version of Autocad and can not open it.
Any chance you can save a version with an older Autocad version
Z14P from 2013 still works up to Z34 ( 11/2014) from Z11P (2016 upwards
it fails)
Thanks Werner

Hi Rick,
Where are the strobe wire shield grounds? Did you keep the strobe ground
isolated from the local (at the strobe) airframe ground? Are your
headphone & mic jacks isolated from the airframe, and grounded only at the
intercom? I've had moderate luck using the old (new?) single point ground
technique shown in 'the book'. Since this is an ongoing issue with two
different kinds of strobes, if it were me, I'd look at running an isolated
strobe ground back to battery negative, or as close as is practical. What
you *don't* want is the strobe and your low level audio stuff sharing the
same ground path back to the battery negative. If that happens, the audio
equipment's power supply (and likely the audio signal itself) sees the
'ripple' of noise from the strobes.
It's conceivable that the old strobes were radiating into the radio's RF
input, but I wouldn't have thought that the LED version would be as bad.
Last (probably should have been first), you say 'strobe noise', but say it
stops when the alternator is off. That doesn't sound like strobe noise; it
sounds like alternator noise. Is the sound there when the alternator is on,
but the strobes are off? Is (was) it the 'woop, woop' sound as the strobe
fires, or continuous whine, or static, or ??? Does it vary in pitch or
volume with engine rpm?
If it's actually alternator noise, you probably still need to look at
grounds. Make sure the alternator has a 'zero resistance' (clean)
connection to the engine, and that the engine has a perfect, low impedance
ground back to the battery negative (can be through a firewall ground stud,
but that should go directly to the battery). If you're using the steel cage
in the Glastar for ground, make sure that *all* ground terminations to the
cage Battery location could be a factor; is it at the firewall or behind
the luggage compartment?
If all the grounds truly are good (only way to know for sure, without
specialized test gear, is to unbolt and examine the mating surfaces), and
it really is alternator noise instead of strobe noise, you might have a bad
diode or two in the alternator itself.
Charlie

Thanks for the help. The strobe noise is the 'woop woop' sound. It was
much woopier with the Whelen strobes but it's clearly happening when the
strobes flash. And it does stop when the strobes are off.
There are sort-of two ground points now. There's a terminal strip in the
forward cockpit that all the non-avionics stuff such as lights are
grounded to. The ground wire from the battery runs to a large stud at
one end of that terminal strip. There's another large stud on the other
end with a large wire going to the engine. When I built the new panel I
incorporated a DB-25 central ground connector on the panel with
redundant connections to that terminal strip.
The strobes are not grounded at the wingtip. I ran the wire back to the
grounding terminal strip. I guess it's safe to say the strobe ground
does share the audio ground back to the battery.
That said, I suppose it could be alternator noise. The strobes do cause
a fairly significant current spike when they flash. Maybe I'm really
hearing the alternator working harder during those moments.
