This circuit is applied to supervise if auto power supply voltage12V is normal or not. If the power supply voltageis 12~14.5 V, then it is normal, whenit is lower than 12V or higher than 14.5V,the indicator will be lit up. A(1), A(2) are indicator comparators for adjusting potentiometers W (1), W (2). When thecar's power supply voltage is higherthan 1.45 V, lamp B is on; or it is lower than 12V,lamp A is on;Normal, these two lights are not bright.
