GEA 24 connected

My Garmin 9-pin connectors have been in Sweden for six days now, either stuck in customs or at Post Nord :(

I could not keep myself from trying out the GEA 24 so I carefully used the can bus terminator to connect pwr, gnd and can bus hi+lo to the GEA24.

I then turned it on, before configuring anything, my little extra battery that I use was drained to much so I had to take a break to charge it. I then tried again. Only a few items worked, I was surprisingly fast in finding the problem, the other GEA 24 connectors were not connected! Quick fix and then I got some believable results so my wiring cannot be completely off :)

Control cables in place

All control cables are in place.
Mixture required only careful setting to get a perfect result.
Throttle required a new hole in the arm that the cable attaches to, to get the proper throw, great result.

The Prop control is working fine but with it setup so that I get full forward with just a tiny cushion at the handle, I can only go down to about 45% before I hit the stop at the governor. I´m sure it would work fine like this but I would have a difficult time setting the RPM to the exact wanted value. The solution is described by Tim O on VAF and consists of buying a longer arm for the governor.

Wires and pins for the GEA 24, 9 pin connector are done and resting in a can-bus terminator, waiting for the proper connectors that might show up in the mailbox tomorrow.

More control cables

Getting the cables in place without having the possibility to detach the throttle quadrant would have been very difficult.

Prop control is in place at both ends. Throttle is connected inside the canopy. Mixture is in place at both ends but I need to tweak it some, when it is set at full on the engine side, there is about 1/4 inch left at the quadrant, I want them all to be very close to the front mechanical stop when at full forward so I dont destroy anything if I push hart on the controls at an unexpected go-around... So please ignore pictures with cotter pins barely in place, they are not final yet.

Another motivation booster

Got the adahrs calibrated and saw the horizon working for the first time :)

Prop governor control cable

First I crimped pins onto the dimmer wires and put them into the GAD 27 connector then I felt that I needed to do some non-electrical work so I attached the prop control cable on the governor side.

Dimmer pots

Dimmer pots in place but I think they stick out to far... Will do something about that later.

Another GEA24 connector done

The strange comment bug is here again, I just cannot reply to comments from any of my devices.

Another connector is done, this one contains all the pressure sensors, fuel flow, alt-amp and oil temp. It looks like I have misplaced the 9-pin contacts so I cannot wire power to the GEA 24 at the moment.

More power

Finished the GDU470 contact. Connected power first to the GSU25 and then to the GAD27. After verifying those connections I finally connected the keep alive power from the GAD27 to the GDU470, GTN625 and GSU25 via some fuses.

Still no smoke

So tonight I wired up power to the GDU470 and set up the GoPro for recording, still no smoke :)

10/1/18

No smoke :)

I finished the GTN625 connector. Assembled the 625 back plate and connected the power and ground wires. I put in a 3 amp fuse and temporary wired my small 12v battery to the connectors on the FW side.

With the camera set up I flipped the master switch and it turned on. Of course complaining about not having the card with map data and so on. But no smoke!

Disconnected everything and went inside just to discover that today was the day that the cameras SD-card decided to die :( So I missed recording this event, one camera is simply not enough for important events!

GTN 625 pins

Just about done with the GTN 625 connector. I noticed that not all cables needed for an ELT-GPS connection exist in the harness so I ran a 2x20 shielded cable all the way from the panel to the tail.

Reminder for myself: RS232-1
Shield is 232-gnd

Lots of wires, main power in place

First I realized that I had totally forgotten to wire the left traditional magnet. I fixed that and supported some emag cables better.

I have finally gotten my 80amp ANL fuses so I ended with wiring up the main power distribution. (Alternator, ANL, shunt, Bat-main fuse block-MGL ECB) Hopefully this is as messy as it will ever get and that it will look better and better from now on.

FW forward wires

Lots of things done in the last two days but not much to show in pictures. Basically all the wiring on the front side of the FW is done now. All wires are either grounded on the engine side or going thru the two openings in the FW.

Front plate for fuse holder

I need a bigger/better CNC mill! I cannot trust the CNC to keep its position so milled slowly using a G-code command at a time.

Cables & Switches

Work from today and yesterday. Added switches to the panel mid section and made a cutout for the planned ICOM 220. Then I started installing the control cables.






9/11/18

Master switch

I connected the Master Switch and placed a small 12v battery on top of the "real" battery and connected it after verifying that no power cables touched anything. I then tested the Master Switch and got the typical "chunk" sound from the engaging Master Relay.


Problem with comments

I have continued with more CAN BUS wiring, not much to show. I do not want to pull more wires thru the firewall before I have put the engine control cables thru the same holes.


For some reason I am not able to respond to the comment in the last post... twice I have responded and the posts just disappears. So my reply below:


Damaged goods are unfortunately very common nowadays. Totally lost goods also happens. I have been lucky, I think this is the first time ever that I have had a shipment lost or significantly damaged.

Shit happens...

My shipment from Vans with among other things my custom control cables was lost/destroyed during shipment.


Shit happens as they say, I must say that both FedEx and Van´s have handled the incident perfectly and to be honest I have and will not loose much time because of this. I have had lots of tasks to perform that was not depending of this shipment, I just have been prioritizing family and non aviation related things for the last 5-6 weeks.


Last night I spliced cables from the pressure senders, no pics from that, sorry. I am also almost done with the primary electrical system so a first start up of the EFIS and GPS in the panel should not be far away.
