I have an analog schematics consisting of LM393 voltage comparators, op-amps, current meter & logic gates. The purpose of the circuit if to turn on red LED while battery connected to circuit is charging and to turn off red and turn on green LED when battery is charged. The circuit works for red LED, but not for green. I need someone to check why's that happening. More details, schematics and more detail description of schematics will be provided when job is awarded.
