Removing the battery

Before you disconnect the battery, make sure you know all the codes for your vehicle, such as radio theft codes, preset radio frequencies, etc. Otherwise, after repair, it will be possible to put the radio receiver into operation only at a specialized station. In addition, most of the information will be lost in the electronic control system. However, it will turn on the emergency program and restore all data after a few kilometers. If after that you have any complaints about the operation of the car, for example, unstable engine idling, visit a service center where specialists read the memory of the electronic control system and correct the error in a few minutes.

By the way, this advice applies to all work in which the battery is disconnected from the vehicle's on-board network.



SEQUENCE OF WORK

1. To prevent a short circuit during further work, first disconnect the wire from the negative terminal of the battery. To do this, unscrew the nut and disconnect the wire contact from the battery terminal.

2. Turn away a nut and disconnect a wire from the positive plug of the storage battery.

3. Remove nuts 1 (pic. 15.8) securing the battery bar and remove the bar 4.

4. Remove the battery.

5. When installing, make sure that the battery is securely installed on the console (slipping of the battery leads to the destruction of the lead plates).

6. Connect at first a wire to positive, then a wire to negative plugs of the storage battery. An error when connecting wires to the terminals is eliminated due to the fact that the battery terminals are of different diameters.

7. Lubricate the terminals with petroleum jelly or special battery lubricant to prevent the formation of sulfates.

8. Turn on the radio and enter the code into it.
