My cousin and I are trying to convert my 2010 Obi saber with removable blade using the tutorial for the Anakin removable blade conversion as a wiring guide, and we thought everything was going smoothly until we tried to test it. The LED flickers when the pins first make contact with the battery pack, but that's it. It doesn't come on, and there is no sound from the speaker. We checked the wiring with the photos on the tutorial, and everything seems to be correct. We disconnected the LED from the board, and tested it directly on the battery connections, and it lit up fine, but still didn't make any sound. Does anyone have any advice?
