Nuckolls, III) ________________________________ Message 1 _____________________________________ Time: 04:27:47 PM PST US From: Kevin Horton Subject: AeroElectric-List: Bad fast-on connection? I fought a GNS430W TX issue a while ago that was eventually apparently resolved by reseating the fast-on connector where the power line connects to the fuse block. The radio had worked fine for 2.5 years, then suddenly was transmitting carrier only. I ran out of ideas, so I eventually pulled the power connector off the fuse block, squeezed the fast-on a bit with pliers, and wiggled it back on, and the radio worked fine for five weeks. Today it was not transmitting again. I removed, squeezed and reinstalled the same fast-on connector again, and the problem appears to be solved, again. I'm baffled by why this fast-on seems to be giving me grief. Both the fast-on connectors and the fuse block were purchased from B&C Specialties, so I believe they are good quality. I'm not sure what I should do to hopefully permanently fix the issue. I'd appreciate any comments on the following possible courses of action, plus I'd love any other suggestions: 1. cut off the problem fast-on, splice the wire with a butt splice and install a new fast-on (the wire is not long enough to do this unless I splice it). 2. use dielectric grease on the connection, such as the Dynatex product sold by Stein Avionics: http://www.steinair.com/chemicals.htm http://www.accumetricinc.com/dynatex/PDF/49634.pdf 3. replace the Buss fuse block (purchased from B&C Specialites) with a new one. 4. bypass the fuse block with a ring terminal connected to the fuse block's input, and an inline fuse. This gets rid of the fast-on connector in this circuit, but replaces it with a ring terminal.

From: Matt Prather Hi Kevin, I'm sure you'll get other smart replies, but here are my thoughts.. - Have you done something to verify that it's a deficiency in the fast-on-spade interconnect? Short of an alloy problem, an overheat, or ongoing mechanical stress, I have a tough time believing that's the problem. - Could it be that when you pull the fast-on off the spade, you're resetting some other connection in the functional chain? A bad crimp? Some other loose connection? - Is there another hot connection available on the fuse block? - Is that an always-hot connection (battery bus)? - I assume the fuse block is in the cabin where it stays dry and at a reasonable temperature... - If you cut the connector off, save it for Bob.. He'll probably want to look at it. ;) Matt- On May 9, 2011, at 5:19 PM, Kevin Horton wrote: > > I fought a GNS430W TX issue a while ago that was eventually apparently resolved by reseating the fast-on connector where the power line connects to the fuse block.

Hi Kevin, My 2 cents is on the crimped connection of the fast on tab. I don't know what size the wire is, but I'm guessing that it is very light gauge. With the very light gauge wires (< 20AWG) I have better luck getting a good crimp by stripping twice the length of wire needed & folding in half prior to installing the terminal. Hope this helps.

He'll probably >want to look at it. ;) Good suggestions Matt. I wish I knew where B&C buys inventory these days. There IS a potential problem with fast-ons crafted from softer alloys. The fact that you EVER had to 'tighten' this terminal gives one pause to wonder. Get a minimum 10-pak of these http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name-903-ND and use to replace the fast-on already installed. Also, see if you can exchange the 'problem' wire with another terminal that powers a lower current draw/less critical accessory. If you need to make a wire longer, use a soldered lap-splice under heatshrink to extend the wire. http://www.aeroelectric.com/articles/Solder_Lap_Splicing/Solder_Lap_Splices.html Bob . . . ________________________________ Message 8 _____________________________________ Time: 08:01:20 PM PST US From: "Robert L.
