The reasons why the Pacific Automotive Network alternator fault light is on are: the alternator is not synchronized; alternator temperature increases; the alternator stator winding is damaged; the alternator rotor winding is grounded; When the unbalance of the three-phase load of the generator exceeds the allowable value, the rotor temperature will also increase. At this time, the load should be reduced immediately and the system should be adjusted to reduce the imbalance of the three-phase load. that the rotor temperature falls within the permitted range.
Reasons the generator fault light is on include: the generator is not synchronized; generator temperature increases; the generator stator winding is damaged; the generator rotor winding is grounded.
Generator Failure Measures: 1. Whenhe generators are put in parallel using the quasi-synchronous method, they must meet the three conditions of same voltage, cycle and phase.
2. When the three-phase load unbalance of the generator exceeds the allowable value, the rotor temperature will also increase. At this time, the load should be reduced immediately and efforts should be made to adjust the temperature. system to reduce the imbalance of the three-phase load. Reduce the rotor temperature within the permitted range.
3. If you see a fire on the generator arc, the generator relay protection device will operate immediately, causing the main switch, field switch and emergency circuit breaker to trip, and the generator will shut down to function.
4. If the rotor's two-point grounding protection device is activated, its relay will also operate. At this time, the main circuit breakerThe generator must be shut off immediately to decouple the generator from the system. and stop, and at the same time turn off the de-excitation switch, set the magnetic field rheostat to the maximum resistance position, and check the rotor and excitation system after stopping.
Why the car won't start and the battery light comes on?
Let me tell you how to deal with the check engine light that s 'lights as follows:
1. Read the error code:
You can contact a professional auto repair shop or use a car fault diagnosis device to read the error code to determine the specific cause of the fault. .
2. Check the motor:
Check the motor for abnormal noises, vibrations or odors. If this is the case, there may be problems such as damage to internal engine parts or poor lubrication.
3. Vericheck the fuel system:
If the engine failure is related to the fuel system, you can check whether the fuel pump, fuel injector, fuel filter and other components are working . correctly.
This may be due to low battery voltage. It is recommended to check it as soon as possible. If the battery light on your car's dashboard lights up, it means the car battery has a problem. Theyellow lightis on, indicating that the battery is low or dead.
This will prevent the car from starting. At that time, you can start it using an electrical device and run it for a while to store electricity after starting; try again, the yellow light will disappear and the battery will return to normal. If the red light comes on, it is not just a battery problem, but apower supply system failure. At this time, it is recommended to turn off the car's electrical equipment and call for help.
The reason why the battery light is on
1. The engine is generating.The car battery light will turn on if the electrical voltage is lower than the battery voltage, the generator is not working, or the power line is faulty. At that time, you should go to the repair shop to check the generator and charging line.
2. The battery light on the dashboard is a warning light indicating that the generator is not producing electricity. Typically, it turns on after turning the ignition switch to the ON position and turns off after starting. the engine. If the light is still on after the car is turned on, it means the generator may not be producing electricity or there may be a problem.th with the wiring and you need to go to the maintenance station for maintenance.
If the generator does not generate electricity, during the process of driving the car, the electrical equipment can only rely on the battery for power supply, and the battery will not be charged when battery power is used. the engine stalls or the car does not start.
3. When the car battery is low, the battery indicator light will also light up. However, you can continue to use it in this case. Because the battery can be charged by the generator inside the engine while the car is driving.
