This is one of those things that looks useful up front, but it's like counting calories. Naturally, the total weight of all your wire before the install will differ greatly after the install. The best approach might be to use this at the end. Collect all your receipts for wire purchases, subtract the waste and enter the balance. Ok, you'll have your estimated wire weight and now you can decide whether using that #2 cable for the #19 rear battery install was too heavy and then rip it all out :) Sort of like having concrete rails on my snow sled - but fun. -----Original Message----- From: owner-aeroelectric-list-server@matronics.com [mailto:owner-aeroelectric-list-server@matronics.com] On Behalf Of jayb Sent: Sunday, February 03, 2008 3:36 PM Subject: [Probable SPAM] AeroElectric-List: Mil-W-5088L Wire Size Calculator spreadsheet --> PRetty handy wire size calculator spreadsheet is attached. Has anyone used it before? I've been playing around with it some and it looks to be pretty accurate. There may be a newer version, but I haven't yet been able to locate the author (Scott Dahlgren) to ask...

Well, I got a hold of the AT guys at garmin per Matt's info (thanks again Matt) They advised that you CAN NOT power the com and nav sides from different voltages, if you do you radio will let out all the "magic smoke" and no longer function. So I will be doing something like the above to safe guard the DC50 box. Thanks again to all. ________________________________ Message 3 _____________________________________ Time: 05:57:49 PM PST US From: "Michael Hinchcliff" Subject: AeroElectric-List: TDR-950 Contacts Can somebody tell me where I can find replacement contacts for a Collins TDR-950 transponder connector?

Are there any markings on the connector that would tell us what it's pedigree might be? Can you send us a picture of the housing?
