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?

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 http://contrails.free.fr http://lapierre.skunkworks.free.fr ________________________________ Message 2 _____________________________________ Time: 03:06:40 AM PST US Subject: Re: AeroElectric-List: Garmin 400 series display replacement From: GTH Le 03/04/2021 10:03, Peter Pengilly a crit: > > 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.

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! -- Best regards, Gilles http://contrails.free.fr http://lapierre.skunkworks.free.fr ________________________________ Message 3 _____________________________________ Time: 06:52:35 AM PST US From: Michael Burbidge Subject: AeroElectric-List: Splicing shielded pair Hi, Is there a video or instructions somewhere that describe how to splice shie lded pair wire? Thanks, Michael- ________________________________ Message 4 _____________________________________ Time: 03:59:34 PM PST US From: Subject: AeroElectric-List: 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 ________________________________ Message 5 _____________________________________ Time: 04:33:43 PM PST US Subject: Re: AeroElectric-List: Thermocouple Accuracy From: Kelly McMullen 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.

You could probably adapt that technique. See the three photos at the bottom of my blog post Wiring Harness Installed . Cheers, -- Art Z.
