The 5.5 and this broken newer 8" do not have strain reliefs. It is like a small volcano made as part of the white plastic top cover.
I was forced to cut away that cone part, then keep digging out some sort of amber colored stiff glue stuff. I had to keep jambing thin tools down along the black cable and finally it broke loose..
Ok, I see why the guts got loose; The copper coils are set into a very crappy Styrofoam disc that is crumbly. Then they used 4 applied radial lines of some glue, to hold this unit to the top cover. So, when the coil gets bumped way too many times, the 4 glued strip areas, ripped out of this weak foam disc.
there is a hole in that foam disc, so the cable wiring could be soldered. That area is then filled with the amber glue which is very stiff, but somewhat a bit stretchy, not rock hard.
The end of the black cable is buried in this stuff, but I can see a red wire that was soldered to a tiny copper hair sized wire, and that is broken...
but, I had no idea that there is also a tiny hair wire stuck in black paint, running in a V shape on the underside of the top white cover.. and that is broken too. I did know there is the same hair wire in a V shaped, painted into the bottom cover, but that one is not broken
So, I doubt two wires broke at once, so maybe I broke one? I can't yet see in the wad of amber glue, to see how many wires come out of the black cable
so, if I can somehow solder the two broken wires, then I will try to bench test the coil, before ever trying to find a way to glue all the components back together.
Let me start a new thread on the older 8" that I have apart. That one went crazy during a wet grass hunt. I figured it was water inside, but now I suspect it might have broken wires instead.
