How to check if the car's alternator is not producing electricity?
Hello! The method you mentioned is too complicated and risky. For example, in an EFI car, if you lose power, a series of fault lights may illuminate on the dashboard and the audio anti-theft device may malfunction. The simplest and most effective method is to start the car and use a screwdriver, which we call a screwdriver, near the generator pulley. If the screwdriver is suckedIf placed on the pulley, this means that the generator is producing electricity. This method is used for models with exposed generators, but the engine runs, so pay attention to safety!
If the car's generator is not producing electricity, all of the car's electrical devices can only use power from the battery. It is best to power only spark plugs if you turn on the headlights, turn on the air conditioner and work. with the radiator and condenser fan it will be faster to drain the battery. In fact, it is very simple to detect whether the generator is producing electricity. There are two methods:
1. Look at the battery light.
When the ignition key is turned to the ON position, the battery light will turn on and before the engine is started, it will not turn off. After starting the engine, if the generator is operating normally, the light will turn off. If the genator operates abnormally, the indicator light will go out. on.
The principle is very simple. One end of the light is connected to the ignition switch and the other end is connected to the generator. When the generator is not working, the voltage is 0. After the generator. The ignition key is on, the voltage is the battery voltage. At this time, both ends of the indicator light have a voltage drop, which creates a current that causes the indicator light to illuminate. When the generator starts producing electricity, the voltage increases and there is high voltage on both sides of the indicator light. If there is no voltage drop, there is no current and the light goes out.
2. Measure the voltage with a multimeter
The standard battery voltage is 12 volts, and the generator output voltage is approximately 14 volts. use a multimeter to measure the battery voltage. If the voltage is higher than when the motorr is off, it means the generator is normal. If the voltage is lower than when the engine is off, it means the generator is not producing electricity. .
Under normal circumstances, you just need to look at the battery light.
