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. The previous coils may have appeared inside the generator. Short circuit or open circuit, worn carbon brushes or itThere may be a problem with the 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.
The reasons why the engine cannot ignite are:
1. The battery is insufficient or dead For problems such as engine incapacitation. Start, For diagnosis, the battery must be tested first. It is necessary to know if the battery power is insufficient if the engine cannot start. If the battery is insufficient, the battery needs to be charged.
2. Engine starting system failure. For problems such as the engine not being able to start, the first step is to detect the circuit in the engine starting system. In the most basic form of composition, the starting system circuit generally includesThe most basic elements are the battery, the starter motor and the cables connecting these components. Of course, the vehicle's ignition switch, starter relay or electromagnetic coil, and anti-theft system are also important components of the starting system. If the starting system is damaged, you must go to a 4S workshop for repair.
3. Engine ignition system failure. In early ignition systems, it was easy to remove the ignition coil and use a spark detector to check if the spark was normal. If the ignition system fails, you can clean the carbon deposits or replace the spark plugs.
Here are the reasons why the engine cannot start. You can check them one by one.
