Hellzero Posted 4 hours ago Posted 4 hours ago Unsolder that red wire for the moment as it's the power (tension) for the LED, so not really mandatory to check the circuit. Clean these solders as they have a lot of tin. 😉 And try again as the red LED should only turn on in active mode when wired correctly. If it's working without the LED shining as it's not powered, just take a multimeter and check where the power is located and that'll be it. 1 Quote
