If the car starter hardly turns, then it is worth checking electrolyte density in the accumulator. For this purpose rather special areometer. If density of electrolyte is insufficient, then it is necessary to undertake a number of actions for resuscitation of the accumulator – to recharge it and to increase electrolyte density.
It is required to you
- autotester or multimeter, charger, fresh electrolyte
Instruction
1. Recharge and install the accumulator on the car. Parallel to terminals of the accumulator connect the autotester included in the voltmeter mode. The arrow of an autotester has to stand in a yellow zone. The multimeter has to show voltage of 11.9 - 12.5 volts.
2. Start the engine, bring its turns to 2.5 thousand about. in min. Measure tension on accumulator terminals. When checking has to be an autotester in the mode of the voltmeter, the shooter in the green sector. The multimeter has to show tension 13.9 - 14.4 Volta. If tension did not change, so there is no current of charging and the car demands repair, and charging accumulator. Charge the accumulator with current which value (in Amperes) is 10 times less than battery capacity (in Amper*chas) within 10 hours. Charging you make the next 2 hours current (in Amperes), smaller from battery capacity (in Amper*chas) by 20 times. For example, at the capacity of the battery of 60 amper*chas the first current of charging is equal to 6 amperes, the second is equal to 3 amperes. (The second mode is leveling, is used for alignment of density of electrolyte in all banks of the accumulator). Charge the accumulator, intensive gas emission in all banks will not begin yet.
3. If when checking on the car with the started engine tension on terminals of the accumulator rose higher than 14.4 volts, so the relay regulator of the car is faulty and demands repair, and electrolyte in the accumulator constantly strongly boiled away. As in such cases electrolyte is literally splashed out, and add to accumulators for alignment of level of electrolyte only the distilled water, there is nothing surprising in the low level of density of electrolyte. In that case completely charge the accumulator and level electrolyte density in banks, casting old and weak electrolyte and adding fresh. Do this operation only on completely charged accumulator, be guided on tension on terminals which at the switched-off and disconnected charger has to be 12.7 Volta.
