Symptoms of a bad alternator regulator: The battery cannot fully maintain electrical power, leading to a gradual decrease in battery power and even the inability to start the car. The standard battery voltage is 12V, and it can reach 14V when the battery is fully charged (the engine working state). Virtual lights on cars, screens, etc. when the battery is discharged (when the generator is not producing electricity). turn on, they don't
What are the symptoms of a broken generator regulator
Symptoms of a broken generator regulator: The battery cannot fully maintain the power supply, resulting in a loss of power to the battery. gradually decrease, or even fail Start the car. The standard battery voltage is 12V, and it can reach 14V when the battery is fullloaded (the operating state of the engine). Virtual lights on cars, screens, etc. when the battery is discharged (when the generator is not producing electricity). Are bright, they are not working properly and indicate intermittent operation.
As its name suggests, the regulator regulates the power generated by the generator. Since the speed of the car engine is uncertain and the generator is driven by the engine, in order to stabilize the electricity generated by the generator at about 14.0V, the internal magnetic field current of the generator needs to be adjusted . When the speed is low, the regulation current is large; when the speed is high, the regulating current is small, so that the generator can output constant voltage.
At present, alternators are widely used in automobiles. The following points should be considered whentheir use:
1. Frequently clean the scale and dust from the outside of the generator. to keep it clean and in good condition;
3. The tension of the transmission belt must be appropriate. If it is too loose, it will slip easily and result in insufficient power production; if it is too tight, it will easily damage the belt and generator bearings
4. When installing the battery, do not install it; incorrectly. Usually install the positive wire first, do not install the ground wire, otherwise the diode will be easily burned out.
5. When using an integrated circuit regulator, the ignition switch should be turned off immediately when the engine is not running
6. Never use the “scrape” method of testing whether; electricity is generated;
7. When the generator cannot generate electricity, it should be eliminated in time, otherwise it will causes more serious defects.
What should you pay attention to when maintaining and inspecting the generator?
Points to note when servicing and inspecting generators: Make sure there are no problems with this part of the connection. On the other hand, it is necessary to carefully check whether the insulation between the turns of the rotating coil is intact. Good insulation is a prerequisite for normal operation of the generator.
Reduce the effects of magnetic flux. The generator set core end plate is equipped with a conductive shield, which can function as a magnetic baffle. And since most core end plates are stepped, this shape can increase local magnetic resistance and achieve better heat dissipation.
At the same time, in singleThe division of sheets in the element can increase the resistance and extend the path of eddy currents, rthus reducing eddy current losses. Additionally, when designing the core ends, overall considerations must be made not only to reduce eddy current losses as much as possible, but also to maintain appropriate thermal and magnetic characteristics. Laminations must be made from low-loss materials at the right time and must be made with uniform pressure.
Demagnetize the field coil by demagnetizing the component. Routine maintenance and repair of generator rotors should be strengthened. If the rotor is grounded, the fault must be eliminated in time. Workers should always check the exciter, grounding pad insulation, oil pipe insulation, etc. Detailed instructions are given during routine maintenance of the generator set; in addition, the motor components to be demagnetized can bebe placed in the excitation coil, which can increase the excitation current, and when the demagnetization component is lifted, the current can be reduced. When the current reaches zero, demagnetization is complete. What are the symptoms of a broken generator regulator? What should you pay attention to when repairing and inspecting the generator @2019
When there is no ammeter on the dashboard of the car, an external direct current ammeter can be used to detect it.
The car generator is mainly composed of rotor, stator, rectifier and end cover. Its function is to power the car equipment and charge the battery when the engine is turned on. the car engine is running.
Turn the multimeter knob to DC 30V voltage gear, connect the red test lead to the terminalne "armature" from the generator and the black test lead to the case. Leave the engine running at medium speed or higher. The standard voltage value of 12V electrical system should be around 14V. The standard voltage value of 24V electrical system should be around 28V. If the measured voltage is the battery voltage, it means that the car's alternator is broken.
Check the vehicle
If the car does not stall immediately, change the speed of the accelerator pedal and observe whether the voltage between the terminal positive output of the generator and the ground fluctuate, if the voltage is unstable or the voltage is not around 12V, the generator is damaged. If it operates normally, remove the positive battery terminal. If the car stalls immediately, the alternator may not be able to produce electricity.
Check the generator rotor, check if the slip rings are safethem and ablated, and use a multimeter to measure if there is continuity between the slip rings. Then check the degree of insulation of the winding from the magnetic field. If the measured resistance value is infinite, it means it is normal. Motor vehicle generators are essentially alternators. When measuring alternator quality, be careful and never use the "scraping" method. tests whether it is necessary to produce electricity. If the generator does not operate normally, it is recommended to go to a maintenance point and have it repaired by professional technicians.
