Default AMBrc DP Transponder wire?

Hello, not sure where to post this, but I have an AMBrc DP 2wire xponder and the red wire where it meets the xponder is completely showing and looks like its barely hanging on.... if it was farther out it would be a easy fix, but it is where it touches the actual xponder. Is there a way to open it up, or fix a wire that close?

I've seen a video on YouTube somewhere where they show how to cut open up the transponder and solder a new wire to the board. It obviously completely destroys the existing case and so once repaired they used heat shrink to cover the transponder. Of course you then loose its waterproofness etc. You can also return it to AMBrc for repair but that obviously comes with a cost.

theres a picture, its hard to see... but to give you an idea.

I might have to check out the Youtube video and resolder it to the board, doesn't seem hard, just hate destroying the case.

Do you have any idea how much it is for AMBrc to repair it? Just a ballpark

Thanks for the info!

Ive taken one of those apart before. I had to ruin the case to get it out and there wasn't much to solder onto once out. The electrics are epoxied into the case so there isn't really a way to solder directly to the board. Once out of the case though there should be enough to splice a new wire onto. I did that and slid a larger piece of heat shrink over the epoxied board for some protection.

If you use clear epoxy (double buble) you don't need a case. Just takes a little time, patience and precision. Just take your exacto knife and score through the seam line all around until you cut the red plastic and peel the case off. Using a dremel with a carbide bit (very small ball tip) I grind the epoxy over the wires until they are expose (just be careful and grind a bit at the time. Once you solder the new wires you can use epoxy (clear) to seal the wires to waterproof the xpdr. No rocket science.

I've no idea about the cost of an AMBrc repair but 50-60% value new wouldn't surprise me. The older transponder you have is easier to get open than the newer Harry type transponders so I would be inclined to give it a shot myself.

My Laps doesn't repair their transponders so I'm guessing these AMB's fall into that same category.

this can be opened up.. but it takes alot to open the 2 case sides.. snug fit,,, and wire can be replaced.. id used a hot gun and apply some heat not alot.. and a 5 in 1 tool works good to pry case apart.. some rtv will work good to hold sides together after fix.i can repair this..$20 shipping is all yours ..

Thanks for all the advice guys, I'm going to try popping it open this weekend and resoldering. Will see how things go!
