My intention was to fabricate the connecting harness. But the the high density 78 pin connector included in the box has tiny machined gold contats, and I am concerned my 4-indent B&C crimper might not do. Here is my question : What do I need to corrrectly hook up and insert those pins at a reasonable price ? Or do I have to order a precrimped harness ? I believe the connector is the same as the GNS 430. Thanks for your advice, Gilles ________________________________ Message 2 _____________________________________ Time: 06:11:37 AM PST US From: "Robert L.

The small wire going into the rear of an alternator with built in regulator is NOT the field supply wire. It's a CONTROL wire to an integrated circuit within the regulator. Further, on some alternators, this control wire is just to DELAY onset of alternator activity until after the engine is started and the electronic fuel control system thinks it's okay to add load to the engine . . . once turned ON by this wire, it cannot be turned OFF except by stopping the engine. Last, there are failure modes within such alternators that completely bypass the control function to produce a runaway condition capable of 100 volts or more output from your alternator. > If just pulling the field >to ground is all I need, what do you recommend, and do you sale the OV >protector? I designed the OVM-14 crowbar ov protection module and used to sell it from my website. The parts and materials business exploded on me and became a third full time job. I transferred that activity to B&C at http://www.bandc.biz a few years ago. You can get the OVM-14 ov module and the companion S701-1 continuous duty contactor from them if you so choose. There is also an article on my website at http://www.aeroelectric.com/articles/crowbar.pdf that explains how to do your own. I will invite you to join us on the AeroElectric List to continue this and similar discussions. It's useful to share the information with as many folks as possible.

Depending on who's adhesive is supplied and how old it is, the self sticking feature can have a problematical service life. However, if you purchase the screw-mount versions -OR- strip the adhesive pad off the back, you can mount these to a clean aluminum surface with a good epoxy like JB Weld. If you need a standoff mounting that does not penetrate the panel, consider mounting a threaded spacer on a 1" square piece of aluminum using flathead screw, then bond aluminum base to back side of instrument panel. I've also used JB Weld to attach aluminum L-brackets to the back of a panel to provide mounting surface for wire bundle clamps, small accessory items, etc. Bob . . . ________________________________ Message 6 _____________________________________ Time: 11:58:19 AM PST US From: "rwilliams" Subject: Re: AeroElectric-List: Common questions --> AeroElectric-List message posted by: "rwilliams" A Nuckoll's online FAQ is a superb idea! ________________________________ Message 7 _____________________________________ Time: 02:45:19 PM PST US From: "Phil Birkelbach" Subject: Re: AeroElectric-List: Common questions --> AeroElectric-List message posted by: "Phil Birkelbach" There is a FAQ. It is called 'The AeroElectric Connection' and it can be purchased from Bob himself or the Builders Bookstore. www.aeroelectric.com http://www.buildersbooks.com/aeroelectric_connection.htm?38,57 I do electrical designs for a living and I learned a LOT from this book. If you are planning to wire your own airplane then you MUST buy this book. At $31 it is a wash compared to all the grief that you will save. Besides, Bob spends a bunch of time on this list answering our questions and asks nothing in return. Go buy the book.

I have two questions... One does anybody see anything that will cause me any grief? and two, I noticed that I am missing the wire size between the main bus and the battery contactor. I considered 4AWG just to be on the safe side but I was wondering if there was any need to go with wire that big or if I could get away with something smaller. I am trying to build the system around a 40A alternator but with the capability to go to 60A in the future if I decide to. Here is a *.pdf of the system so far... http://www.myrv7.com/drawings/727WB-001.pdf Godspeed, Phil Birkelbach - Houston Texas RV-7 N727WB (Reserved) - Canopy http://www.myrv7.com ________________________________ Message 9 _____________________________________ Time: 04:45:10 PM PST US From: "ted scott" Subject: AeroElectric-List: Flap motor wireing --> AeroElectric-List message posted by: "ted scott" I am installing a flap actuator like the one sold by Aircraft Spruce part #05-66223 and need a wiring diagram and some information on how to get the three positions on this unit.

Today I finally wired it up, but when I went to install it the thing broke! I was tightening the nut with a 7/32" socket between my FINGERS, not even using a wrench, just twisting the socket between my thumb and index finger. The barrel just snapped as soon as it got tight. I couldn't possibly have put that much torque on the thing. The threaded barrel literally split on a thread...it didn't separate, though, just kind of split about 3/4 of the way around. I couldn't get the nut off, so I had to cut it out of there with a pair of wire cutters. I was surprised at how cheap this switch ended up being.

I always think of >B&C as selling top-quality stuff! Unless they've changed suppliers from what I originally stocked for this part, the manufacturer was Grayhill . . . an old line, respected supplier to the industry. See: http://216.55.140.222/temp/39_Series.pdf I sold several dozen of those switches before B&C took over the activity and I've personally used perhaps a dozen more in personal projects over the past 20+ years. Unless we can find some evidence to the contrary, I'd like to believe your experience was an isolated incident borne of a batch QA problem. I note from the spec sheet cited above that rated installation torque for the part is 2-in lbs, not really hefty but it is, after all, a rather petite part. I would expect the mounting bushing to be good for at least twice that before failure. Given the difficulty you had removing the carcass, there would probably be no value in having you send me the failed part. I'll ask B&C to pull a couple from stock and send them down to me for examination and testing. I'm certain they'll be pleased to replace the one that broke for you . . . but let's wait until we gage the condition of other switches in stock.

Since the rest of the airplane's fat wires are 4AWG, you've probably already got enough left over to do the main bus feed with 4AWG too . . . which would be fine. To drive a 60A bus, you can downsize to 6AWG. 8AWG would be fine for a 40A system . . . unless you're going to add electric toe warmers, I cannot imagine that you'd ever need a 60A machine. The drawing looks fine.

That stuff is designed to etch the metal at solder temperatures, and it will continue to corrode things forever, albeit slowly, if you don't remove it. Get a temperature controlled soldering iron and very fine rosin core solder, practice a little and you'll be fine. Also get an eye loupe or some sort of magnifier for inspection. As far as an insertion tool, none is needed. Just need it to remove a pin from the connector.

Am I right in supposing that proper technique means pre tinning the parts, using not too much solder, etc..?

Be aware that such systems may have failure modes that can cause unexpected, uncommanded flap motion. Do you plan to have a flap position indicator? Unless the airplane has VERY powerful flaps like the early "barn door" flaps on high wing Cessnas, I think you'll find that you can control flaps with the simple spring-loaded, center off switch without even looking at the flap indicator. Configuring automatic controls with safeguards adds a degree of complexity that may not be good value in terms of overall flap system reliability. Is this feature a matter of consensus among Kis owners as to need or just a neat, gee-whiz? Kirk Hammersmith and I tossed around the notion of a similar system for Lancairs at the factory . . . after some thought, I suggested that we not mess up what has proven to be a perfectly good working system.

It's really no big deal other than minor disappointment. I swung down to Radio Crack and bought their equivalent sub-mini switch (blister pack of 2 for $2.79). I'm sure it's an inferior switch, but it has a beefier barrel. Already installed. 8-) I just wanted to raise the issue in case it's something I did -- sounds like I over-torqued it, even with my fingers. But even so, the switch doesn't come with a lock washer, nor did the barrel seem long enough to get a lock washer on there.
