| Subject: | Garmin 400 series display replacement |
As far as I know Garmin are still supporting the 400 series, you may be better
off sending it in.
The European repair centre is in Southampton.
A customer with 2 x GNC430 in a DA40 arrived at work a couple of years ago with
both units not working correctly.
In the end we had to send both back to Garmin for repair. He had disassembled both
and made errors in assembly.
Might be worth asking your local service centre what the cost will be?

Subject: AeroElectric-List: Garmin 400 series display replacement
Hello all,
Our Garmin GPS 400 memory battery was successfully replaced some months ago, thanks
to the advices on the list.
Here is a small summary which could help (only in French at the moment, but if
you ask...)
http://contrails.free.fr/instruments_bat_gps.php
Now another issue : the display begins to show some faded areas.
Question : does someone on the list know of a source for a replacement
screen?
Any input appreciated,
Thanks in advance,

Best regards,
Gilles

Peter,
Thank you for answering.
Of course the Garmin service center is the way to go, and we'll try it
when everything else fails, but Garmin charges are outrageous.
Battery replacement is charged several hundreds of dollars for a part
available in the next DIY store for a few bucks/quids/euros.
So *if* the part is available to end customers, I'd try and replace it
at home. The Garmin is more or less a small computer with two i386
processors in a very neat and sturdy housing.
LCDs for various Garmin GPSs sell for $15-20 on the Web.
But yes, I'll ask the service center in Luxembourg, they sold us the
unit some 18 years ago!

| Subject: | Thermocouple Accuracy |
I put my CHT sensors into boiling water at sea level and got a reading of
200 deg F and got 22 deg F with them in ice water. Is this close enough?
I am using a MGL EFIS unit
All 4 sensors provide the same reading plus or minus 1 or 2 degrees
Sensors are K type attached to a copper washer that fits under the spark
plug
Thanks
Mike

unless you put a lot of salt in the water for the freezing part, that
reading should be very close to 32 degrees. The boiling temp is fine,
takes some effort to get the water above 200.

Michael,
I soldered ground wires to the shields. You could probably adapt that
technique. See the three photos at the bottom of my blog post Wiring
Harness Installed
<https://cheerfulcurmudgeon.com/2016/11/28/wiring-harness-installed/>.
Cheers,

One end of the thermocouple wire is attached to the copper ring under the pl
ug, the other end is connected to the MGL RDAC unit that feeds signal to the
EFIS. There are no joins in the wire
