Well my light arrived today, this one:-

first impression was excellent until I tried to use it. By a process of elimination I have found that the charger works fine, the light works fine and the batteries themselves seem ok. But there is something wrong with the lead from battery pack, the one that either connects to the light or the charger. Push fit and set it up as normal and everything is dead as a dodo. However bend the wire just before the connecting socket, requires a certain direction and amount of pressure, and everything works fine.
Have sent them a message via e-bay on this but I'm not prepared to spend any dosh shipping stuff back, I made that decision when I purchased. So we could be looking at a bit of home maintenance here
what's inside one of the molded plastic socket things? How is the wire actually connected and is it fixable by amateur who has tools and is patient? I'm guessing I could also buy a new battery pack but I'd still face the problem of needing the right connector fitted to it.
