I didn't write that last post very well. Looks a bit like I'm saying I'm fixing mine and it keeps coming unfixed.
No. Mine is broken and I can't fix it.
What I was saying I've heard they can be fixed just by pulling them apart and cleaning the inside.
I read a thread about reconditioning them and all they did was pull it apart, clean it - get the can electroplated - and put it back together.
No, all I've done to mine so far is clean the contacts - and that hasn't helped.
