I replaced the B2 broken arm and cut all of the 7 wires and soldered them back on the right places.....except that black antenna wire which is just like a Sirius Radio antenna wire: a night mare to re solder and even worse with the hot-glue the manufacturers squeezed over the area. The youtube video shows how the person snipped the wires with a pair of scissors and used a big wedged solder point to resolder them all back....except the footage where it looks like they just resoldered the end of the snipped wires back on their globbed solder pad. I tried to use my Celestron hand-held microscope to see if I could locate where in hell they soldered that wire to. I could not tell. To the left of the blob is another labeled "antenna pad", which looks like it is bare from use. This black wire has braided shielding around a clear insulated center wire, does anyone know if the braided wire and the center wire are soldered together on that spot, or, if the braised wire solders to a spot and the center wire goes to another spot. The youtube video shows the person just soldering the wire back in place without doing anything but using that big solder tip to solder it back. I called holy stone and they would not tell me anything and do not help out with any suggestions to fix circuit boards. The circuit board is fine. And, if this wire is connected wrong, or shorted (like the video shows when they just soldered it back) will it burn the board up or just not communicate or drop from the sky......thank you for any help.
