Once the generator is damaged, the battery light will turn on, but it will not turn off immediately because there is still some electricity in the battery. However, it stalls after riding for a while. Generally speaking, for Buick brand vehicles, a new car can be driven for approximately 90 minutes without turning on the lights or air conditioning.
The reasons why the car generator is not producing electricity are:
First, the generator belt slips or the belt breaks.
Second, when the generator is not energized or energized, you can place a tool on the front end of the pulley to detect if there is a magnetic field. If there is a magnetic field, it always has been. normal. Otherwise, he's not excited. Previous reels may have appeared. Short circuit or open circuit, worn carbon brushes or there may be a problem withthe excitation power supply. Plus, it's a powerful word, and the belt is normal. If it's not producing electricity, it's usually due to the voltage regulator or rectifier inside the generator.
Causes and solutions for car failure to start:
1 The gear may be incorrect. When starting a car with an automatic transmission, the gear must be placed in P or N. If it is placed in R or D, it will not start. There are also manual transmission cars that will not start unless the clutch is depressed.
2. The battery is discharged. This may be due to loss of power or expiry of battery life for reasons such as leaving the headlights off for a long period of time. It is generally recommended to replace the battery every two years. Additionally, the installation of argon headlights, high-power audio, DVDs, etc. hert also causes vehicle circuit failures. It's easy to check if the vehicle is off, just press the horn to find out.
3. Spark plug. Generally, the most common thing to do is to check the car's spark plug first, because this spark plug is a key part of the car's ignition system, and the car's ignition system vehicle is the key to knowing whether the car's heart engine is working, therefore whether the spark plug can work normally and affects the performance and efficiency of the vehicle. Emergency method: you can unscrew the spark plug and wipe it clean. You can start the car after reinstalling it. A thorough approach is to check the ignition system and eliminate the causes of low ignition energy, such as spark plug electrode gap, ignition coil energy, l high line status tension, etc.
