Penza drivers were given advice on working with the battery

For an experienced car owner, the battery removal procedure may seem elementary. However, if you confuse the order of disconnection of wires, you can arrange a short circuit and damage expensive electronics. Experts strongly advise the first thing to take on the negative terminal.

The secret lies in the design of the car: the negative conclusion is closed on the body, that is, on the “mass”. If you first unscrew the "plus", then any careless swing of a wrench that touched both the terminal and the metal of the body will cause a powerful spark. This can melt the wires or cause a fire. The red protective cap on the plus terminal only prevents accidental circuits when driving, but does not dictate the order of work.

Before you start, turn off the engine, turn off the headlights and tape, and then wait a couple of minutes until the control units are asleep. Arm yourself with a carob key (most often 10), loosen the puff on the minus wire, remove it and put it aside. Only now you can move on to the plus terminal. If the compounds are oxidized and do not lend themselves, do not use brute force - carefully shake them or use a removable.

The assembly is in a mirror order: first we throw and tighten the plus, and then the minus. Then we check the reliability of the fixation and turn on the ignition.

Errors with a working engine are fraught with failure of the ECU or fuses. The restoration of wiring will cost a penny, and the repair of the electronic unit can cost up to 15 thousand rubles. Take care of nerves and technique – observe the correct sequence.
