Battery Voltage Monitor (CB1425E )

   This circuit came out in a 1978 American publication, but can be assembled with transistors BC547 or BC548. The circuit indicates the state of the car battery through 3 LEDs: normal weak and above voltage. The trigger point of the LEDs is determined by the zener diodes, which can be changed.
