Hello,
The wire inside the tailcap that connects the pcb to the spring broke. Soldering it back is not the problem. But I needed to turn the spring pcb counterclockwise to get it out to resolder it. After resoldering the wire from the spring pcb to the tailcap pcb, I needed to turn it clockwise to screw the tailcap back in… this is where the problem lies… when screwing it back, the wire gets twisted and break again. Any advice?
