And the first thing we look at is the generator. We strive to this view not just like that, but because our generator flatly refused to work, and we have to go on the battery. If this breakdown occurred on the Zhiguli, then you can get out of the situation as follows. To reduce energy consumption and, accordingly, to drive more, you should first turn off the excitation winding of the generator. For what we turn off the corresponding fuse and disconnect the wire from the relay of the lamp, signaling the battery charge. After such simple operations on a single battery, you can drive as much as 200 kilometers.
The second trick is useful only to those whose car is not equipped with a contactless ignition system. It will be needed if all the electrician suddenly refused, and all the appliances turned off. That is, for some mysterious reasons, the power supply has stopped. You can, of course, investigate why this very filing has stopped, but you can do it easier, without investigating anything at all. Just throw a thick wire from the "plus" terminal to the ignition coil and start the engine with the start handle.
