In July of 2008, I purchased a Fenix P2D from an Amazon seller. Starting about a week and a half ago, the light would no longer turn on. I have tried cleaning the threads as some have suggested, and I even tried the L1D body that came with the pack that I got. The L1D body has its own switch, and i tried it with a fresh battery in each of the bodies. Does anybody have any idea of anything else I might try? The seller I bought it from on Amazon doesn't have a website, so I don't know how to get the light repaired. I'd get a different flashlight, but I really like having the interchangeable bodies in case I need to use a AA battery sometime. Thanks for any suggestions anybody might have.
