Check of level of acid in the accumulator
The liquid in the accumulator consists of the sulfuric acid diluted with distilled water. The part of this water can evaporate or break up to hydrogen and oxygen during accumulator gymnastics.
In Audi the so-called accumulator which is not subject to maintenance service which большего liquid volume should for the account, under normal circumstances is established, throughout all term of the service to do without addition of the distilled water.

- The liquid in the accumulator should reach, at least, bottom of two marks which put by a varnish on the case or have been beaten out on it of strips, and it is good to cover an upper edge of plates.
- If liquid level has fallen, unscrew a stopper.
- If the accumulator is charged normally add the distilled water to the top mark or on 15 mm above an upper edge of plates.
- If the accumulator was strongly discharged, add so much water, how many it is necessary to cover plates. At gymnastics liquid level considerably rises.
- The distilled water add to the top mark only after accumulator gymnastics.
- The quantity of added water should be dosed well out, differently the accumulator will be overflowed.
- The overflowed accumulator перекипает too much, acid acts from under a stopper

Accumulator dismantle
|
|
Accumulator dismantle: remove a decontamination hose. In the beginning ослабьте the plug of a minus (3), then remove facing плюсового poles (4) and unscrew the plug of plus (5). Now it is possible to weaken a bolt (1) on a fixing guard (2) bases of the accumulator. |

- In the beginning be convinced available a code for the coding device against radio receiver theft that it could be made active again after installation.
- In the beginning always disconnect a wire connected to a minus that in the course of the further work there was no short circuit.
- Loosen the a nut on the plug of a minus pole, disconnect the plug.
- Loosen the the plug плюсового poles also disconnect.
- Unscrew a bolt of a fixing lath at the accumulator basis, take out a bolt and remove a lath.
- Remove a plastic hose of the central decontamination.
- Remove the accumulator.
- At installation in the beginning connect a wire to plus, then the minus plug.
- To change wire plugs it is possible in the event that to make only the big effort, as a head плюсового poles thicker than a head of the minus.
- Do not forget about a hose of the central decontamination.
- In the presence of a radio receiver with a code against theft again enter code number.

Care of accumulator contacts
|
|
- Смойте crystals oxide warm alkaline water or process Noutralon firms Varta.
- Grease heads of poles of the accumulator and the plug of wires with means for protection against acid (Bosch Ft 40 v 1).
- It is impossible to grease lateral faces of heads of poles and an inside of plugs, differently there can be difficulties with contact.
