The self-category of the storage battery

Depending on the car equipment to the natural self-category of the battery current consumption by various electric devices in an idle condition is added also. Therefore in not used car not less often than an once in 6 weeks it is necessary to recharge the storage battery.

If there is a suspicion on presence of currents of leak, check up an onboard network as follows:


1. For check use the charged battery.

2. Switch off all consumers, disconnect hours, close doors and a cowl. Close a luggage carrier cover.

3. Disconnect from the storage battery a weight cable.

At a battery detachment records in memory of malfunctions are erased. Before battery switching-off familiarise with Section Removal and installation of the storage battery.

4. Establish on the ampermeter (a range of measurement 0 - 5) the top range of measurements. Include the ampermeter between a negative pole of the battery (-) and a weight cable (-). Address to an accompanying illustration.

Check can be executed also a control lamp. If the lamp included between weight and a negative pole of the battery, does not light up, it is necessary to apply the ampermeter necessarily.

5. Switch with амперного a range on миллиамперный until there will be an instrument reading (enough 1 - 3 мА).

6. Taking out consistently one safety lock behind another, disconnect corresponding electric chains. If at disconnection of one of chains the ampermeter shows zero, here there is a damage source. Damages can be: the rusted or polluted contacts, the ground electric wires, internally short circuit in units.

If in the electric chains protected by safety locks, malfunction is not found, it is necessary to disconnect wires at not protected units, such as ignition system, the generator and a starter.

If at a detachment of one of not protected units the ampermeter shows a zero, it is necessary to repair or replace this unit. In the presence of current leaks in a starter or ignition system it is necessary to check up always as well the ignition switch.

Attach a weight cable (-) to the storage battery.
