I noticed yesterday that I have a problem with audio output of the GPS. I have no audio on the spaker or on the intercom. I made a few tests and got in contact with Garmin, they send me a replacement part, I'll see next week if it works.
In the meantime I changed the GPS connexion by installing a D-sub connector which will make testing easier and maybe switch to another GPS.



I also laced some of the harnesses, the left side is now almost done.

After some tidying up of the intercom wiring, I install the fuse to get some electrons flowing. I have a green light so all worked well. I test the intercom functions between each side, and it works.



I then switch on the radio and the fuse blows. After some investigation I fond that one of the plug is missing it's insulation washer. I then can test the reception by listening to the traffic at the nearby Lognes airport.
Next I try some transmission, but with no luck. First thing I find is there is a problem with one of the BNC connectors on the cable. I replace it, but I still have no transmission.
Some more investigation show that I have been mislead by one of the wiring diagrams and reversed two wires on the plug I soldered yesterday. After the wire are switched, I successfully test the transmission, the red light illuminates on the intercom panel and I can hear the transmission on a hand held radio.



Today we also completed the 2000th hour building.

Some more work on the intercom. I have to rewire one of the mike plugs as the wires are a bit too short. The soldering has to be done in situ which poses some challenges.



I then finish the wiring of the intercom connector and connect all the shields and grounds (12 wires in total). I also notice that my intercom drawing is somewhat wrong and need some time to sort everything out.
The picture shows the audio mixer on the left (the gray D-sub connector) and the intercom connector on the right.



I do all this work under the supervision of Fany our new house pet.

After some small tasks, I installed the LED showing that the auxiliary battery is charging. I hesitated quite some time before installing it near the battery switch. The LED sould remain off most of the time after the battery is charged after the beginning of a flight.



I then wired the audio mixer and the intercom. The connections on the audio mixer are done, there are a few wires remaining on the intercom connector.
Most of the wires are shielded and the shields have to be connected. To do this, I leave a few millimeter of shield apparent.



I then use a solder sleeve installed with a heat gun.

To hold down the side hinge pins there are a few documented methods. I tried to use some circular insert where the lower screw would hold the pin and the upper screw would hold the insert to the upper cowl. But it proved difficult to get right. The picture shows that.



I decided to use a small stainless steel strip to screw down the hinge pin end.



The hole in the cowl gets covered by an aluminium part thet is much easier to install being greater than the opening.



This is the second, it looks quite good. Only thing left is to find a nice finisn , maybe get it engraved.



And here I'm with my Dad, this week' helper, and we are quite happy with was we managed to perform.
