Why does the generator not producing electricity light come on?

If there is a problem with the generator, the charging light is always on after starting. If the generator is not producing electricity, if there is no problem with the wiring, there is often a problem with the diode. Now check if there is any problem with the circuit. Generally, use a multimeter to measure the resistance or use a test light to check if the diode is broken, just replace the diode.

It is easy to distinguish between producing electricity and not producing electricity. If the generator is properly connected and still not producing electricity, there is a fault.

Usually the generator voltage regulator is faulty. If the light is still on or not at all, you may want to consider replacing the regulator as a first step.

If replacing the regulator still fails to resolve the problem and the excitation lineis normal, you can check the rotor resistance value, which is usually a few ohms. If it is greater than 10 ohms or 0, it is not. considered a rotor defect.

The rotor was replaced normally by the generator rectifier circuit board, and the stator coil was almost not burned out.

Once the generator is damaged, the battery light will turn on, but it will not turn off immediately because there is still some electrical energy 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 energizednor powered on, 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 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.
