Delivery time and price was as expected. Note that I did not use ebay, etc to purchase this, I went directly to their web site No phone number was provided on the invoice, but the address is: PO Box 10605 Bozeman, MT 59719 The web site is http://www.gilchrist-electric.com The web site shows phone number as 409-586-6507.

The hi density pins are .050 in diameter (where the crimp takes place) while the standard pins are .075. But my crimper contracts to about .025 diameter. So I tried a couple and found the wire is nicely crimped. You do have to be careful to position the pin correctly in the crimper as they are different lengths. But to do a few crimps, a standard d sub crimper seems to work OK.

MD200-306 CDI 4/14/2008 Hello Bruce, You wrote: "Can you point me to the catalog locations or suppliers with the correct items numbers?" I will try -- first a little basic information. The 430W and the SL30 both put out and receive multiple signals to and from the 106A. So you need two devices. One device is a relatively simple push to activate switch on the instrument panel which shifts the pilot's navigation choice from one source (430W) to the other (SL30) or vice versa. This device should also have a light indication on it to show which choice has been made. The other device is remotely activated, more complicated, and it consists of many relays and contact points that when activated by device number one shifts all of the many signal paths between the 430W, the SL30, and the 106A. There are multiple manufacturers and sources for both device one and device two so one can shop around for their preference and purchase sources. Here is a source for device one: http://www.gulf-coast-avionics.com/list.asp?search_type=2&search_text=NAT Here are some sources for device two: http://www.sandia.aero/?q=SR64 http://www.trast-aero.com/eng/catalog/view.php?ModelId=401 These two sources are not intended to give you "ready to buy" information, but rather to show you what kinds of devices you are looking for and some possible items to purchase. It will take some leg work on your part to discover the best devices for your use and the best sources to purchase them from. Perhaps other members on the list (Stein Bruch?) can also provide some more specific choices / recommendations and sources. 'OC' Says: "The best investment we can make is the effort to gather and understand knowledge." PS: I have some Excel spread sheets that I made up that show my equipment and the rather complicated wiring interconnections. If you think that they might be of use to you please email me direct and I will send them to you as email attachments. --------------------------------------------------------------------- Time: 07:04:12 PM PST US Subject: Avionics-List: Re: GARMIN GI-106A VS. MD200-306 CDI From: "Rv9APlane" Hi OC, I am new to the list and saw this today. I am planning the same equipment , i.e., a 430W, SL30, and 106A. I am not familiar with the items you mentioned about switching back and forth. Can you point me to the catalog locations or suppliers with the correct items numbers? I'm pretty weak on the electrical stuff although I reading up on it now(Bob Nuckolls book). Thanks for your help. -------- Bruce Peters RV9A, Fuselage Bakersfield, CA ________________________________ Message 6 _____________________________________ Time: 07:13:46 AM PST US From: Subject: AeroElectric-List: Re: Shunts Oh my my.

Interesting . . . it seems that the same folks would also make fun of neurosurgeons, master chefs and physicists. Individuals who poke fun at the assemblage of simple-ideas into useful inventions are themselves at-risk for not enjoying the benefits that arise from understanding . . . a kind of self imposed exile to ignorance that leaves them dependent upon those who DO understand. > Yes voltage, current and EMF are all magically intertwined. Nothing magic about it. But the conditions under which they interact are not consistent. For example, just because there is voltage to be measured doesn't automatically translate to a current flow. Similarly, there are conditions where huge magnitudes of current flow with zero impressed voltage. >Even the magic of the hall effect sender puts out proportional >volts to current. Sort of . . . volts is proportional to the intensity of a magnetic field. The magnetic field can come from a variety of sources not the least of which is the field surrounding a current carrying conductor. >But you all are right, there are coils in those mechanical gauges. >However a digital meter will read directly off a shunt? Huha? What? >Doha! ha-ha. Yes, the digital voltmeter takes advantage of the voltage drop impressed across a shunt as a result of current flow. The measurements obtained by this method are independent of simple-ideas involving magnetics. >Bob your "VAM10_Interior_View link" is not working?

In fact, it's possible on some airplanes that an alternator will run reasonably well without a battery . . . complete loss of the contactor may not be immediately noticed. If you're looking for loose wires, everything between the bus and BOTH power sources (alternator and battery) should be examined. Unless you soldered your terminals on a good tug on the fat-wire terminals is in order. I've seen wires installed with inadequate crimp tools pull out of their respective terminals without a whole lot of effort.
