Automotive Voltage Indicator
The connection track on the car battery, you will always know that a close look at the available voltage.
This shows that the battery voltage is useful to monitor the driving battery capable of providing current, and the efficiency of the inspection as a generator or generators.
Threshold voltage light-emitting diodes are built by the means of Zener diode (D6 & a number of cell D10), together with two other cable series diode (D4 category, D 5 categories and D8, D9, respectively) increased by approximately 1.3V step The nominal voltage regulator.
