The car battery testing process

The car battery detection:

◇ car is turned off when the car is all electrical accessories are closed.

◇ Generator belt is loose, the son and connectors to whether it is clean, whether caused by the leakage of poor contact.

◇ generator or voltage regulator is working properly.

◇ All electrical accessories, installation of generators is beyond capacity.

◇ status circuit power is good, whether rightly or wrongly phenomenon of short-circuit, if the increased resistance of joints Department.

◇ For the over-discharge of the VGP-BPL9 battery is full complement of power.

◇ long term does not disconnect the car battery is connected to other components, such as the absence of the battery is depleted due to unable to start car.

Note:

◇ recharge the battery has not failed to question, but if this happens often run out of battery is very energy is the problem of vehicles. The need vehicles to perform a thorough inspection

Including the charging system and the leakage is not a normal phenomenon.

◇     Less than 30 mA of leakage current is a normal phenomenon, because some of the car equipped with a clock, anti-theft devices, microprocessors and other small accessories.

 

How can I check the amount of leakage?

◇ cut the engine and vehicle supply for all electrical accessories.

◇ mA scale would be an ammeter with a string in the circuit, then negative on the 361742-001 battery, the volume until you get the correct values in place. Less than 30 mA

The amount of leakage is normal, exceeding 30 mA, check the circuit electrical accessories, so it is normal.

 

How do I check the alternator?

◆ visual Attorney

View the alternator belt is loose, the battery cables and alternators

Cable connection is dense.

◆ alternator test preparation

◇ will be a voltmeter in the circuit a parallel access, meter connected to the alternator highlight the positive side of the counter negative end connected to the generator on the body.

◇ be a string current meter in AC generator power point production, the value is the output value of the current generator.

◇ will be a carbon rheostat in parallel with the PA3399U-2BRS battery box to simulate power accessories of the vehicle.

◆ generator when the engine idling detection

◇ make the engine idling.

◇ adjust rheostat to obtain the maximum power generators. But the tension is less than 13V, observe the current value, then cut the power rheostat. This number

Value must be marked with the generator shell on the present value of the same, the error of 10% as the error is much in need of repair the generator.

◆ like when the engine driving the generator test

◇ increased engine speed (about 3000 rpm) to a stable voltage and current.

◇ adjust rheostat to obtain the maximum power generators. But the tension is less than A1008 13V, observe the current value, then cut the power rheostat. This number

Value must be marked with the generator shell on the present value of the same, the error of 10% as the error is much in need of repair the generator.

◆ operating voltage regulator test voltage

◇ failure voltage regulator would result in the charging voltage is too high or too low, too high will cause the battery charge, low battery cause insufficient curing plate.

◇ so that engine speed is about 3000 rpm voltage readings observed, this value should be between 13.5-14.7, if not in this range, the production of electricity

Machine or voltage regulator is correct.

◇ voltmeter then in parallel with the battery, the observed values, this value should be between 13.5-14.7, as shown in the value of a qualified and not in this range

Inside, it may be due to loose joints, or high resistance, etc., it will cause a generator to charge the battery does not work correctly. Please check the circuit.
