Battery Fault Diagnosis and Troubleshooting

• • Capacity reduction

1.Failure phenomenon: When starting the engine with the starter when the starter has become slow and unable to speed quickly.
2. Fault reasons: (1) the new battery is not enough electricity, or stored for too long without a charge and discharge cycle of the exercise. (2) The generator regulator voltage regulator is too low, so that battery charging less frequently. (3) often prolonged use of starters, resulting in large current discharge, resulting in damage to battery plates. (4) electrolyte density lower than the specified value, or electrolyte leakage after filling only distilled water, resulting in reduced electrolyte density. (5) electrolyte density is too high or too low surface frequently, or use distilled water instead of a single electrolyte filling, causing plate curing. (6) generator regulator voltage regulator is too high, the charge current is too large, resulting in a very board battery active material shedding.

• • Self-discharge

1, failure phenomenon: charge batteries, or the day before the use of sound into the next day a much lower voltage, resulting in weak rotation starter, and the horn sounds low and weak.
2, failure reasons: (1) to connect the battery wires are leakage of the office. (2) short-circuit between the battery plates. (3) electrolyte containing impurities. (4) The deposition of impurities bottom too much battery short circuit, or battery cover dirty, overflow caused by excessive electrolyte battery pole short-circuit.
3, fault diagnosis and rule out the
First, the external battery should be checked whether it is clean, especially the battery cover whether there is dirt accumulation. Then check whether the Da Tie wire, short circuit of the Department. Inspection of all electrical equipment can be shut down, remove the batteries a terminal on the wire, with the terminal end of the line drawn fire touch test. If spark, should check the wires paragraph by paragraph to identify Datie of the Department; if not sparks, indicating the internal fault in the battery should be repaired apart.

• • Excessive electrolyte loss

1, failure phenomenon: electrolyte depletion extraordinary, require frequent filling of distilled water to make up for wear and tear.
2, failure reasons: (1) battery shell with crack, so that the loss of electrolyte leakage. (2) The charge current is too large. (3), plate curing, or short-circuit
3, fault diagnosis and rule out: Check the link when other symptoms that make judgments. First check whether the crack shell leaks, electrolyte leakage after the filling of distilled water each time, will inevitably lead to electrolyte density decreased, battery save enough electricity. In the case of generator regulator voltage regulator is too high, often accompanied by burned-out bulbs and so on. If you use a single cell were found in the liquid drop much faster, it is likely that this shell of a single cell or a crack sealant at Ershi electrolyte leakage. If the single-cell shell and sealing agents are good, there may be a single-cell battery plate curing, or short-circuit. Out the cause of the malfunction diagnosis, after the corresponding repair method to be excluded.

• • Can not be recharged into the electric

1, failure phenomenon: the ammeter in the road after starting a pointer back to the too fast, or the battery temperature too high, and after a long journey that +5 A ammeter pointer still over.
2, failure reasons: (1) battery fatigue. (2) The existence of an internal short-circuit fault. (3) a very active substances fall off the board so that the capacity is too small. (4) The plate curing, or hardening of negative plates.
3, fault diagnosis and exclusion: For the battery can not be recharged into the electric fault diagnosis, fault phenomena according to a comprehensive analysis of its use to make judgments. If the batteries used in more than a year, the above-mentioned phenomenon, usually battery has been fatigue failure, and should be replaced with new pieces. If the battery temperature too high, and a long journey, the ammeter pointer still refers to +5 A above, the high rate of discharge can be used to identify the meter test. If the measured voltage is lower than that of a single-cell 1.5V, to illustrate a single cell within the short-circuit fault, should open the overhaul.
If the electrolyte is poor, generally very active substances fall off the board due to be changed with a new battery. If the start of a second starter, and then start it is clearly unable to show battery "floating power", mostly due to the negative electrode plates vulcanized or hardened due to be carried out restorative charge.
