After ten years of good use, my Powabyke (21-speed model with control box on handlebars) has let me down. On opening the control box, I see that heat damage on the 7-pin plug/socket has caused a break in power to the motor. Having cleaned it up and replugged, it works OK again. I want to replace the plug and socket though. P'byke don't have any and I can't find the same thing at Maplins or RS...so has anyone any ideas? I could hard solder the wire to the board, but I'd rather not.
