Car Accumulator Charge Control Circuit

Car Accumulator Charge Control Circuit (pic.1) reliably works during more than five years on cars VAZ 2101 and VAZ 2107. In the device temperature correction is foreseen overheat - cooling, so an accumulator enables to exploit during the whole year winter - summer, and also defence from the short circuit.
