None of the left and right red LEDS light when in use, only the center green led. Per the schematic (attached) there is -9.7 on the left and right and -10.8 on the common, so those inputs look like they match the schematic values pretty close. However, I don't understand how the LED circuit actually works and shows the measured power. Can someone explain what is supposed to be happening in the circuit?
