Is the carbon supposed to conduct the current between the connections? Does carbon conduct electricity? Can't remember back to whatever class I should've learned that in
Yes that's what is suppose to happen.
HoweverI have had way too many customers with lumenocks that don't work that I had to exchange out. I will be stocking Tracer nocks this year instead of lumenocks. The tracer nocksuse a magnet and a magnetic circuit in the nockand seem to be much more reliable than lumenocks. They also have the added benefit of being able to change batteries when they run downand change the nock should you break one or want a different color.
