The indicator of gymnastics of the accumulator

    The indicator in a combination of devices is supplied by two positive conclusions, namely one from outside plugs D + the generator (a dark blue wire) and another from outside plugs 15 through dark blue multicontact штекерное the connection approaching to the device behind from the lock of ignition (a black-dark blue wire). At ignition inclusion on the plug 15 pressure arrives. The generator, however, for the present does not work, and consequently +-contact being without food D operates as "minus". The indicator flashes, because between the onboard network receiving a food from the accumulator, and the potential difference exists the idle generator. If the engine is started also the generator has reached number of turns necessary for a charge, the pressure regulator connects it to an onboard network. Now a food arrives from the plug 15 and in addition from plug D +. When the potential difference does not exist, the charge indicator dies away. At ignition inclusion the burning indicator of a charge should предвозбудить the generator. Only in this case the generator can already make a current on low turns. However preexcitation is necessary only at the first start of the generator.

Additional charge occurs not always

Even if the charge indicator does not burn, it yet does not mean that the storage battery is really charged. It says only that there is no any more a potential difference between the accumulator and the generator. If idling the engine all consumers of a current the charge indicator does not burn though from the accumulator arrives more current are included, for example, than can выроботать the low-power generator: but nevertheless the difference of pressure with the storage battery does not exist.
