14.1.7. The storage battery

The storage battery is on the right party under a trunk floor.

The prevention

Some serially established automobile radio receivers have coding. Anticreeping coding interferes with incompetent commissioning of the device if the electromaintenance system is interrupted. The electromaintenance system, for example, interrupts at a detachment of wires from plugs of the storage battery, at removal of a radio receiver or if has fused a radio receiver safety lock. If the radio receiver is coded, before a detachment of wires from plugs of the storage battery fix a radio code. If the code is unknown, only firm Mercedes repair truck can place again in operation an automobile radio receiver.

G1. The storage battery


1. It is impossible to insert the ignition key.
2. Disconnect wires from plugs of the storage battery, at first a wire (3) connecting a pole of the storage battery (–) with the car case, then a positive wire (4) (+), for this purpose cast away upwards a protective cover (6).
3. Remove from the storage battery the pipeline (5) for tap of allocated gases.
4. Unscrew and get bolts (1) to a fixing plate (2) on the basis of the storage battery. The storage battery on 100 А-ч has only one bolt.
5. Take the storage battery.
The prevention

Storage batteries contain harmful substances which should not get to household dust. At purchase of the new storage battery old return to the seller or hand over on points of warehousing of a special waste.


1. Before installation clear to shine of a pole of the storage battery, the brush from a brass wire for this purpose approaches. For corrosion prevention both poles cover противокислотной with greasing.
2. Establish the storage battery, spread it on a fixing plate and hardly screw.
3. Pull over the storage battery the pipeline for tap of allocated gases.
4. Attach to plugs a positive wire to a positive pole (+), then negative (case) a wire to a negative pole.
The prevention

Wires to the storage battery connect only at the switched off ignition, the actuation device of system of injection of fuel otherwise can be damaged. Because of wrong connection of the battery there can be considerable damages to the generator and electric system.

Pay attention to irreproachable connections with the case of the car and pure contacts. High transitive resistance of contacts results, especially at start-up, to an overload of electronic actuation devices and can become in an extreme case the reason of their failure.

5. Close a protective cover on a positive pole and fix it.
6. Establish time for hours.
7. Enter an anticreeping code for radio (subsection 14.1.16 see.).
