Hi all,
I tried this before with embedded photos and got rejected. I will try again with attachments.
This is late in this thread but I thought relevant and possibly of interest to some.
I built an RV-6A some years ago. In designing my electrical system, I read the Aeroelectric manual, used many of Bob Nucholls designs and recommendations.
I wanted access to external power without using jumper cables. I wanted to be able to charge my battery, test and run everything in my electrical system during construction as well after completion and, if ever needed, get power away from home.
At some point, I came across one of Bob's articles about a DYI external jack and circuits. I just now checked and found it among articles in the Aeroelectric Connection. Just search "external power" on Bob's website and you will find Hi all,

I built an RV-6A some years ago. In designing my electrical system, I read the Aeroelectric manual, used many of Bob Nucholls designs and recommendations.
I wanted access to external power without the mess of using jumper cables or some clumsy temporary connections. I wanted to be able to charge my battery, test and run everything in my electrical system during construction as well after completion and, if ever needed, get power when away from home.
At some point, I came across one of Bob's articles about a DYI external jack and circuits. I just now checked the website and found it among articles in the Aeroelectric Connection. Just search "external power" on Bob's website and you will find "Low Cost Ground Power Jack for your Airplane."
I used these details to include it into my electrical system. A "Piper type"plug mated with my installed "Piper type" jack with connections to my old automotive commonplace battery charger. I also made the assumption that my battery would act to absorb any fluctuations in the supply voltage. I had the radios on while working on other parts of the project to hear local tower activity for many hours without any ill effects.
Attached, I have included two photos, one of the jack in the closed position (you get some sense of the possible drag) and one with the plug connected.
I enjoyed my RV-6A for three good years but sold it about eight years ago when it was time to downsize and prepare to move to a retirement community.
Great building and flying,
Richard Dudley

That is why I used a new battery to run the devices and a charger to keep the battery topped off.... My assumption is that having the large battery in the loop would absorb any spikes, ripples or other transient events... Worked perfect for me....
Bob... Am I thinking wrong on this concept???
