Here's an interesting problem.

I got a Leef C-M adapter and a LF EO-M3T in the mail today and put them on my 9P+A19 with two 17670s. When the light is held horizontally, it works. When the light is held vertically head up, it works. But when I point the light vertically head down, it does not work. I can twist the tailcap all the way until constant on, tilt the light down, and it will turn off. The only thing I can think of is that there is a small amount of space causing the - end of the cell to loose contact with the tailcap spring. Any thoughts?

1. Clean contacts, DeOxit Gold
2. Stretch out the tailcap spring
3. Go with a spacer from CPFer RPM
4. Go with the Leef spacer button
5. Try a circular neodymium magnet

Stretching the spring seems to have fixed it, thanks.
