Hands, Mind, and Heart

What started as a handful of passionate enthusiasts has developed into a major force—and a significant component—of the aircraft industry.

Electrical Systems Simplified Part 1

8/1/1998 12:00:00 AM By Ron Alexander (originally published in EAA Sport Aviation, August 1998)

Somewhere during the aircraft building process you will encounter the often-dreaded task of installing the electrical system. It is likely that you will not receive a lot of help from your plans or assembly manual. The amount of instruction varies from one airplane to another.

Battery Isolators

12/1/1995 12:00:00 AM BY Bob Nuckolls (originally published in EAA Sport Aviation, December 1995)

Many builders are putting two batteries in their airplanes. Sometimes the craft is a seaplane; it's a real bummer to discover a battery that is too pooped to start an engine while the wind blows the airplane further from shore! Additional reasons for redundancy in chunks of lead include providing independent power for the second half of a dual electronic ignition system.

Aircraft Wiring... Where Do You Begin?

3/1/1995 12:00:00 AM By Tony Bingelis (originally published in EAA Experimenter, March 1995)

If you have never done any wiring, most likely you will not have any of the tools or wiring supplies you will need to fabricate and install your aircraft’s electrical system.

Electrical Grounding

5/1/1994 12:00:00 AM By Tony Bingelis (originally published in EAA Sport Aviation, May 1994)

If yours is an all-metal homebuilt, its electrical system can be made up of single-wire circuits. That is, only one wire will be needed to magically connect each electrical unit or device to its electromotive force... the battery or alternator.

Your Alternate Battery Choice (the Gelled Electrolyte Battery)

1/1/1992 12:00:00 AM By Tony Bingelis (originally published in EAA Sport Aviation, January 1992)

Many homebuilders who have used or are using a sealed immobilized electrolyte battery (a gelled cell type, that is) are quite vocal in their support or condemnation of these batteries.

Developing Your Electrical System Part 3 - Wiring Tips

6/1/1990 12:00:00 AM By Tony Bingelis (originally published in EAA Sport Aviation, June 1990)

WELL, HOW ABOUT THAT! Here you have completed the wiring of the aircraft's alternator and battery circuits, installed the main bus and, at this point, have less than a dozen wires coming up to the instrument panel!

Developing Your Electrical System Part 1 - Basic Preparation

4/1/1990 12:00:00 AM By Tony Bingelis (originally published in EAA Sport Aviation, April 1990)

I already have an alternator for my Lycoming 0-320 engines. It is a small Toyota unit rated at 35 amperes. Naturally, I would prefer to use it in my RV-6 rather than buy another alternator...  provided it can handle all the electrical equipment I plan to install.

12 Volts vs. 24 Volts

12/1/1989 12:00:00 AM By Tony Bingelis (originally published in EAA Sport Aviation, December 1989)

The letter posed this question ... "Which electrical system should I install in my Glasair? A 12 volt system or a 24 volt system?
