If it doesnât light up, try swapping the probes around. The polarity of a tiny, yellow, surface-mount LED is tested with a multimeter. If the positive lead touches the anode and negative touches the cathode, the LED should light up. Diodes certainly arenât the only polarized component.There are tons of parts out there that wonât work if connected incorrectly.f it doesnât light up, try swapping the probes around.
