    From: Larry Mac Donald <lm4@juno.com>
    I have been engaged in a futile search trying to find the d-sub connectors that go between a Gat 1 link trainer and it's recorder and it's performance indicator. The body of the male,pin, connector is part No. 200345-2 and I think the socket part no. is 200346-2. I need two female and three male sockets and the backshells and fasteners that go with them. Does anyone know where I might find these old connectors ? ____________________________________________________________ FREE Stock Report How to Invest in the $70 Billion Bottled Water Boom http://thirdpartyoffers.juno.com/TGL3141/536a37a3a92c037a268cbst04vuc

If these are, in fact, D-subs you should be able to identify them by the number of rows of pins and number of pins. Go to your local Radio Shack and they will probably have them. Roger

    Quick hint...you can use the same connector! That said, if you'd like new connectors we keep them in stock.... Cheers, Stein Do not archive -----Original Message----- From: owner-aeroelectric-list-server@matronics.com [mailto:owner-aeroelectric-list-server@matronics.com] On Behalf Of Dragoon6 Sent: Tuesday, May 06, 2014 11:12 PM Subject: AeroElectric-List: Special Coax Connectors: Apollo Nav/Coms... --> <adverb.elephant@gmail.com> Hello, I am looking for some (apparently) special coax connectors for my Apollo (now Garmin) nav/coms. The old connectors are made by Delta Electronics Manufacturing Corp., part number 4205018N995-000, and are slip-on on one side with a metal flare to help guide the radio coax connector into place, then a center-wire solder and twist-on shielding connection the other end. There are two rectangular flanges for mounting to the nav/com tray. I am told that these are standard for the older Apollo radios but they are somewhat difficult to come by. If anyone is selling any or knows of anyone who has any, i would appreciate it. These connectors float on the tray, which also helps for easy alignment when sliding the radio into the tray. I just need new connectors so I can switch to my RG400 coax from the RG58. Let's see if I can add some photos. -------- Travis Read this topic online here: http://forums.matronics.com/viewtopic.php?p=422941#422941 Attachments: http://forums.matronics.com//files/img_20140504_094054_732.jpg http://forums.matronics.com//files/img_20140504_094042_166.jpg http://forums.matronics.com//files/img_20140504_094028_185.jpg http://forums.matronics.com//files/img_20140504_094003_108.jpg

Does anyone know where I >might find these old connectors ? Actually, those are a pretty vintage connector. I think the first time I saw them on a piece of avionics they were called "Winchester" connectors. Amp took them over as their "M" series and now they're TE (Tyco Connectivity) parts and going obsolete. Everything you wanted to know about these connectors and mating parts is here http://tinyurl.com/n5elt9t Newark, Allied, Mouser et. als. may have some stocks. Otherwise, your doomed to beating the bushes of the obsolete and wayward parts brokers . . . http://tinyurl.com/l32clrc Bob . . .

Most manufacturers went with the TED 9-29-10 connector . . . legend has it that they designed that connector for Ed King waaaayyyy back when. They became popular and were adopted by almost everybody and are still in production. http://tinyurl.com/ob7xtyq I've never encountered the connector you've cited. If you could get me some clearer photos, I'd like to add them to the archives. As to your particular question, are you replacing RG58 because it's damaged or now too short? As Kelly pointed out, unless there are mechanical reasons for replacing the coax, performance gains for replacing it are trivial. Can you unscrew the cap on the back of the connector? I think you'll find an access port to a soldered connection to center conductor under that cap. I note that the shield connection appears to be the legacy BNC-style clamp-ring and gasket. With some care on the workbench, you can salvage and reinstall the old connector. If coax replacement IS indicated, you can also cut off the old RG58 to leave a 6" or so flying lead which you can terminate with a cable female BNC . . . then extend your new installation from that point without risk to the old connector. I'll bet that critter is not easy to find and probably expensive if you do find it. Bob . . .

    Hi Bob, I don't believe he's talking about those (king/icom/etc..)...I think specifically the Delta P/N mentioned used by Apollo/UPSat/Garmin...which are these (not my picture): http://2.bp.blogspot.com/-FBkFonYU8-0/UUHdBy2NWmI/AAAAAAAAHW0/FYiLVN28ZB0/s4 00/IMG_2594.JPG As noted, you can easily install RG58 or RG400 into this connector and they are reusable. They are rare because they are no longer in production, but we have a slew of them in stock just due to normal business with these over the years. What's harder to find is the little shoulder nuts that allow those to float...we have to turn some down by hand on the lathe if we need them!

    Subject: stuck starter motor
    From: Janet Amtmann <jgamtmann2@gmail.com>
    If you put a lamp on the I terminal of the contactor it will indicate a stuck contactor, and probably a running starter motor. If you put the bulb across the starter, it will only indicate if the starter has voltage going to it, i.e. stuck contactor. If the starter engagement device (Bendix) is stuck to keep the motor running without the contactor being engaged there will be no voltage generated unless it is a permanent magnet starter motor. Unless the old Delco starter has enough residual magnetism (does it?) in the field to light a bulb, be it an incandescent or and LED. I'll take the connection to the I terminal, thank you.

    Oh!! Stein, can you send me that schematic in the background (installation instructions for this Delta connector) of the image you attached to your reply? Knowing the proper installation procedures would help if I have to re-use the old connectors. >From your image I see that RG400 can, in fact, work in this style of connector. That's very reassuring. Rather than leave a pig tail of RG58 on the back of the tray, I'd rather go with RG400 the whole way. I've been busy and have not been able to locate any Delta Electronics Manufacturing Corp. distributors: DEMC would not sell directly to me as I'm not a business. Stein, if you know where I could get 4 to 6 of these connectors that would be great. Just the installation instructions though would be a big plus.
