So of course this little drumhead light got to working on me as we all know can happen in this hobby. So, I got the leds, weaponized the hakko with a new tiny tip and some .020 solder and went to work. Went together better than I thought it would. But, no joy. It won't light. Powered at 3vdc, individually, each led lights, but of course that doesn't test the circuit. I get no continuity. Should I? What else should I check? I think I have the led polarity correct throughout. Any help out there on troubleshooting this pcb lighting module? Here's some photos, but not sure how much help they'll be. Thx in advance.
