Too low level of electrolit
Recharge. Evaporation (especially in the summer) Add the distilled water to the ordered level (for the charged accumulator room of the battery).
The electrolit acts from a ventilating cover
Too high зарядное pressure Check up a pressure regulator, if necessary replace it.
Too high level of electrolit Suck away superfluous quantity of electrolit денсиметром with a pipette.
Too low density of electrolit
Electrolit density in one cell it is accurate more low, than in other cells Short circuit in a cell. Replace or restore the storage battery.
Electrolit density in two next cells obviously more low, than in other cells Негерметична the partition, arises spending connection between cells owing to what cells are discharged. Restore the storage battery.
The storage battery is discharged Charge the storage battery.
The generator is faulty Check up the generator, if necessary repair or replace.
Short circuit in an electric network Check up electric system.
The electrolit is diluted by water owing to an error at accumulator maintenance service Modify electrolit structure.
Too high density of electrolit
The electrolit was added Modify electrolit structure.
Too low set capacity, falls pressure
The storage battery is discharged Recharge the storage battery.
Too gymnastics low voltage Check up a pressure regulator, if necessary replace it.
Connecting plugs are weakened or oxidised Clear connecting plugs and slightly grease, especially bottom party, кислотостойкой with protective greasing, tighten fastening screws.
Bad connections on the case of the storage battery – the body engine Check up connections (plug) on the case, if necessary restore metal connections or hardly tighten screw connections.
Too big self-category of the storage battery because of electrolit pollution Replace the storage battery.
Probably, просульфатированы plates of the storage battery (a grey-white touch on positive and negative plates) Charge the storage battery a small current slowly to clean a touch. If after repeated gymnastics and a discharge the set capacity remains too low, replace the battery.
The battery plate is worn out, the active weight of plates has fallen off Replace the storage battery.
Insufficient charge at the storage battery
Malfunction in the generator, a regulator of a tension or linear connections Check up the generator and a tension regulator, repair or replace; fix normally wires.
It is weakened клиновой a belt Tighten or replace клиновой a belt.
Too many consumers of a current are connected Establish more powerful storage battery; probably, apply also more powerful generator.
