In order to prevent a possible short circuit in the electrical circuits of the car, especially during a period of sufficiently long parking, it is advisable to disconnect the power source - the battery. In practice, this is done by disconnecting the negative wire - ground.
It is necessary
Power switch, wires, toggle switch, wrenches
Instructions
Step 1
The easiest way is to remove the wire from the negative terminal of the battery. Take a wrench corresponding to the nut on the terminal, loosen the nut and, removing the wire, fix it in some niche, excluding accidental contact with the negative terminal of the battery.
Step 2
It is more convenient to put a disconnect switch. There are various modifications on sale for every taste. Connect it to the negative wire between the battery and the car body, ensuring good contact. Disconnecting the ground, press one button, before starting the engine, press the other, closing the circuit.
Step 3
In order not to get out of the car and open the hood by turning off and turning on the ground, run the wires from the negative terminal into the passenger compartment. Place the toggle switch in a place convenient for you. Such a switch can only be known to you and at the same time play the role of a "secret" - an anti-theft device. Without knowing the location of the toggle switch, an outsider will not be able to start the engine.
Step 4
Modern cars, stuffed, as they say, with "brains" are not indifferent to the power outage of the electrical on-board network. Many motorists generally consider turning off the mass on such cars completely unnecessary. Their protection system will not allow a short circuit to arise, from which fires still occur on old domestic cars. The leader of such fires is "Zhiguli" ("penny").
Step 5
However, if you leave the car for a long time, then it will be useful to turn off the mass on the "foreign car". In order not to de-energize all electronics and signaling with a siren, connect a 3-5 A fuse in parallel with the disconnector. The current through this fuse will be sufficient for the operation of the electronics and signaling. And in the event of a serious short circuit, the fuse will simply blow.
