Avionics Panel ANL and Shunt

 

RV14 Build April

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 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.

Old cheapos

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.

QB Wing Corrosion/ Primer issue

RV14 Build March

QB Wing Re-Work

Vans has informed me that my wings are part of a batch that didn't get the correct application of primer and are subject to corrosion. Well that sucks! That had me test the wings by wiping a dry rag to see if primer transferred.

It would seem just everywhere I tested.

Then I did a thorough inspection for actual corrosion. While I didn't find a bunch, I did find some.

Not sure what the green dots are, I think the primer, but there looks like some salting could also be from overspray of acetone. 

Finger prints from sweat.

While Im waiting on Vans to answer some questions I decided to get into the wings are clean up everything I could find. Even if it was questionable. Acetone, scotch brite, SEM self etching primer and I did use AKZO where the application was easier with the smaller airbrush.

Cleaned out every possible spot I found we will see what fans says and how this plays out.

Avionics Panel- Radio stack, Final Panel Install and Power up

RV14 Build February

Avionics Panel

This section takes a LONG time since there isn't plans you have to figure it out and execute all on your own.

Time for the radio stack. I slid everything into place to see how it would sit and with having the GNX375 on the bottom the rear end was help up by the subpanel and made the front tip. You can barely see behind the faceplate of the GNX near the top edge but not the bottom.

If I lift up the front of the unit the gap goes away. I know this is next to nothing but I want it to be flush!

So I take a few measurements and start removing material.

At first I tried to do it with sand paper but it was painfully slow. so break out the dremel and get it close. Finish with the sandpaper.

Almost there.

Ahh. Nice and fluhs. Time to mount the avionics racks.

For a second I thought about nutplates, but using #6 nylock nuts was way simpler.

Lucky for me my panel is all one piece and I didn't need a nuplate here to attach the center because it would have interfered with the rack mounting nuts.

All installed!

Close up of the panel after the V speeds were fixed.

Time for the final panel install and hook up. 

All the switches are back in and hooked up.

Screen and the radios are in

MFD hidden plate and iPad mount is in.

Just need to finish the antenna cables. Stein has a nice youtube video on how to do this.

Cut back the plastic

Remove the shielding then cut the plastic back to the next line.

Cut/Removed the center insulator

Install the pin and crimp. Test with a voltmeter.

Install the collar and the end and crimp.

 

Now that the antennas cables are done, hook up the antennas before turning on power. Then Happy dance!
