Avionics LRU Installs and Programming

Avionics Install and Programming

Now that the wings are on time to install the Pitot

luckily I was smart enough to run the wires and tube long enough so everything pulls through the pitot mast.

Running the wire for the OAT.

Pinning the OAT

All set!

Screws have a little lock tight on them and the pito tube is installed! Making progress feels so good!

Securing the service loops.

I installed the Pitot tube inboard of the tie down so I didn't have to worry about it interfering with the tie down ropes. But this cause a new issue to make sure I wasn't interfering with the push rods. Little bending of the pitot and AOA tubes and the routing worked great.

Installed my hidden starter switch power.

Right now just with velcro until im sure I want it here.

The pilot stick has having a loose wiring issue so i cut and repinned the harness.

Pins installed.

Section 53 ELT

 RV14 Build August 21

ELT

Purchased the ELT kit from Vans. Registered it with NOAA.

The install was relatively straight forward. Instead of riveting the beeper to the VS I attached it to the top of the ELT with hook and loop velcro and a zip tie for good measure. The cable was about 12" short to reach the location in the panel I had planned so moving the beeper here allowed for a shorter wire run.

Installing the tester in the panel.

There isn't much material on the faceplate but I did countersink it just because I liked the way it looks. Hopefully it doesn't crack in time.

Avionics Panel, Pito lines

 

RV14 Build April 21

Avionics Panel

Since the wings are going back to Vans I decided to install the pito lines into the fuselage and leave the extra to run into the wings after they are installed.

First I splices the static line in near the fuel pump. Ran 1 end the the AHRS and the other to a back up static source.

Back up static valve, just needs to have the hole drilled in the panel and installed. The switch doesn't take much to engage so Ill probably add a flip up red cover to make sure it doesn't accidentally turn on.

I ended up using a 90 degree fitting to the threaded T on the AHRS, the 90 put less stress on the tube connections.

Then ran it over to the G5.

Pito and static are installed. I need another 90 for the AOA and it will all be ready to run into the wings.

Avionis Panel, Optional Ballenger O2 sensor

This probably isn't needed but after this article I got inspired.

Afterall I have already installed the 10 place circuit breaker panel for just an occasion. I ordered the kit and extra terminal ends so I could rewire with Mil Spec wire and have it be the correct length and because I like to do things the hard way I guess?

The connector on the sensor end you need a small flat head screwdriver to remove the pins. I could have reused the connector housing but didn't know that when I ordered it.

Making my harness. I spriced the ground from the controller and the sensor into 1 and ran it to the main grounding block.

View from the back looking forward. I just used hook and loop velco tape to hold it down for now.

The harness came wired for this ish. I had them install 5' of 3 contactor shielded cable on a GP slot. I dont need the HI just the GP3 and 3Lo. The ballenger manual has some confusion about where to hook the analog ground up to. Im going to try it in the 3Lo first and if that doesn't work ground it with the main grounding block.

Another view of the install.

Avionics Panel ANL and Shunt

Avionics Panel

I Installed the doubler for the ANL and Shunt. Here is my basic plan and layout. Due to the size of the lug on the output side of the battery contacter I moved the copper bus bar from the ANL to the Starter contactor connected to the Battery contactor with another bus bar. I used up all my copper so I made the smallest #8 wire to connect the shunt and the ANL.

Installing the doublers.

Installing the Shunt and wires, ANL and 60amp fuse.

My tiny #8 wire instead of copper bus bar.

Blue wire is the battery master switch, the red wire the starter button.

Every time I think I'm done with the wiring i decide to make another change. I didn't like the way the CPC was connected so I changed one to a bulkhead fitting. The CPC has all the wires from the center of the panel switches. I think stein did it this way to make panel removal easier?

I installed it in below the radio stack. Drilling in the tich spot wasn't easy so it didn't end up pretty but it works.

New pins installed

New Connector.

Next I knew I was going to need more room to install futur things like seat heaters so I decided to add a 10 circuit breaker panel. I added nutplates to the access panel the covers the center tunnel under the avionics sub panel.

Testing the location and fit

Final install. The power wire goes to the main bus so there is power anytime the battery master is on.

I didn't like the way that the cheap DB9 looked and I wanted to splice the RMP wires in to not have to run 2 more RPM wires to the Pmags so I repinned the DB9s for the Pmags.

New Wiring plan.

RPM solder spliced in and the 2 shielded cables are spliced and grounded at the GEA24

New Pins on

2 very nice looking connectors.
