spreadsheet
Life is an estimate. 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.

Calculator spreadsheet
--> <jaybrinkmeyer@yahoo.com>
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...
Regards,
Jay

Good thinking!

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.

TDR-950 transponder connector?
Thanks!

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?
