I need some help. I have a maglite 2D and bought some spacers from Matt (Lumencraft, vestureofblood, awesome guy on the forum) anyway, I can’t get my light to run with them and nimh AA cells. Do I need to modify the spring or use a slug of some kind at the bottom of the battery that goes against the spring of the light? I can short out the spring against the body of the light and it works but when it is screwed together somehow the circuit isn’t made. Any help is appreciated, I usually don’t have problems making a light work.
