Electrical 4

Lots of stuff getting done now! It's all happening fast too. I finally put the connector on the end of the Com2 antenna cable, and connected it to the GX-60 tray.
It was so tight in there to get the nuts on the connector, that I had to super glue the nut to a drift so I could get the thing started. There was no way I was getting my fingers in there!
I also routed the roll servo cable and spliced it back together. I had to split it in order to thread it through ribs and conduit in the plane. There are 12(!) cables in this harness too, and it was murder sitting inside the plane in an awkward position trying to get the connections perfect. I forgot to take a picture of it too. Duh!
Getting all this electrical stuff done is getting me lined up for putting in the centre console for the final time. I don't think it'll be this weekend, because I need to do the floors still. That'll be on the fuselage page when I get to it.

I knew we'd forget to take a picture of something today. That something was the EFIS 1 current sensor. I mounted it on the sub panel, just under the glove box where the main buss feed wire from the battery runs. This will serve as the ammeter for the EFIS 1's engine instruments.

This evening's task was to get started on mounting the EFIS keep alive battery. A good place for this is between the firewall and sub panel near the glove box. I decided to make another hinge down tray to support it, and make access to it easier. Here it is partially riveted.
Here's where it will fit in the plane. Space is tight!
This is approximately where the battery will sit. Maybe a tad further back. I will also mount the shottky diode to the tray, but it has to be insulated from the airframe, so I'll have to put it on some phenolic board or something. Gell cell batteries are good, because you can mount them in practically any orientation.
This evening, I continued with the keep alive battery tray. I riveted it all together, and drilled the holes for the bolts that will secure the rearward end in the plane. I also put some angles in to hold the battery fore-aft. I haven't taken a picture of this yet, but I will do, and post it here next chance I get.

I recieved a big order from Allied Electronics yesterday, so I could get some more stuff done! I started out putting all the D-Sub hoods on the EFIS connections.
I engraved the connection names on the top and bottom of the shells too.
I secured the D-Sub connector for the serial earth wire for the FADEC to EFIS interface.
Here's the other side. It's possible to disconnect this so I can use the health status software and hook up to a PC.
I also finished wiring the oil temp probe and the EFIS ammeter. That about wraps up most of the electrical odds and ends. Tomorrow I'll finish up the second battery.
