I purchased the AN14 extender for my G3 with the intention of using a pair of 17670's and a small spacer. I got everything put together and the light wouldn't power up. I discovered that there is roughly a 2mm gap between the metal sleeves in the G3 body and the AN14, so the circuit can't be completed between the tailcap and the lamp. Is my AN14 defective or am I missing something? I can make a small washer to fit in between the body and the adapter, but I'd rather not add another piece if I don't have to. Any suggestions or advice would be appreciated.
