The only place that remotely meets Garmin's requirements for magnetometer mounting is in the wing tip. The installation manual says that if mounted in a metal wing, there should not be local grounding, all wiring should be twisted pairs. I assume I can use a battery drill to make twisted pairs. How tightly should the wires be twisted (turns/inch etc). The only logical place to run the wiring for the magnetometer is in the same conduit with the rest of the wiring.

It doesn't yield 'baseline' data, i.e. a quantitative measurement of contained energy. When I did the first pass at this study I had a nifty $100, 12-Bit DAS purchased previously for a Beech flight test program. Pairing this device with an array of AA cell holders loaded with 5 ohm resistors allowed me to run batches of cells down at the same time. The data yielded was analyzed in software I can't run under Win7 . . . software that coughed up a scrip file that plotted results to a graph in AutoCAD. Emacs! The Phase II test is being accomplished one cell at a time using a West Mountain Radio battery tester and its companion software. The earlier tests were conducted under a constant resistance load; Phase II is constant current. In both instances, the analysis yielded a Watt-Hours value for energy yielded by each cell. The disadvantage is lack of batch-processing capability. The advantage is that software supplied by WMR runs in my more modern computers and also yields quantitative data. Still got a soft spot in my heart for that $low$ DAS. It ran under Win95 off the parallel port of the laptop. It would gather 1000 samples per second of 12-bit data. In about two weeks of hammer-n-sawing at the bench, I had fabricated and installed a pitch-trim study on the Beechjet that yielded some really nice data . . . along with foundation for fixing a problem that was costing the company $millions$. Those were exciting times . . . Bob . . . ________________________________ Message 6 _____________________________________ Time: 11:48:32 AM PST US From: "Robert L.

Looking at the diagram I have I believe #10 is the center of the nav antenna coax. There are 2 connectors. This is on the longer of the 2, ***NOT*** the one that connects to the KI-205.

You'll note from the install manual is specifically calls out a 2 conductor shielded wire and a 3 conductor shielded wire (one of each) run to the GMU. This is the simplest and cleanest way to do the install as well.the wires are already twisted, already shielded and can be run together. Look at page 24-5 in the install manual (rev. AA) for details. The power, Ground and RS-232 share the three conductor wire with the shield getting sunk to the signal ground on the GMU. I'd recommend just following that install guide..after hundreds of these we've wired this way there hasn't been any issues yet.

With that level of interest maybe reading an article discussing the subject of aeronautical time recording might add to our fellow listers knowledge. Please see the article: =9CWho=99s Got The Time?=9D that can be found on page 36 of the October 2015 issue of Kitplanes magazine. If you don=99t have access to that magazine and article I may be able to provide (upon request) a reasonable copy of the article. Owen C.

I've got a B@%%-load of 3-conductor shielded. You can use it for both the 2 and 3-conductor pathways . . . just ignore one wire in the bundle. How much do you need to make the necessary runs?
