Since the silicon brushless rectifier generator has no brushes and slip rings, it will not cause unstable excitation current or power generation failure due to wear and tear. ablation, it therefore does not require frequent maintenance. However, when the car runs about 30,000 kilometers, it needs to be dismantled and maintained once or regularly to ensure its normal, safe and reliable operation. Figure (A) below shows the typical shape of a brushless silicon rectifier generator. When the charging light is always on, it may be that the field winding of the brushless alternator is grounded or shorted between the windings, the wire on the neutral terminal is broken, this indicates that the load relay coil is open circuit or that the contact is oxidized. , resulting in poor contact or connection of the generator system. Causes such as wires and terminalsdamaged or defective. The specific detection method is as follows: 1. The detection lamp is connected between the magnetic field terminal F and the ground terminal. During maintenance, the detection lamp can be used to connect the magnetic field terminal F and the ground terminal of the voltage regulator. and observe the charging indicator. If the charging light goes out, it means the generator is faulty. Its F terminal may be grounded or the field winding may be shorted. If the charging light is still on, it means there is a circuit fault. The line from the voltage regulator to the generator's F terminal may be grounded. 2. Connect the detection light between the neutral terminal and the ground terminal, start the engine, connect the detection light between the neutral terminal and the ground terminal of the generator, and observe the lighting of the detection light. If the indicatorsensor does not illuminate, remove the wire from the N terminal of the neutral point of the generator and observe the detection indicator: If the detection indicator still does not illuminate, it is a circuit fault and there may be an open circuit between the neutral line of the voltage regulator and the generator terminal; If the detection light is on, the voltage regulator is defective and the voltage regulator needs to be repaired or replaced with a new one. If the detection light is on, use the detection light to check the neutral terminal and ground terminal of the voltage regulator, and observe the status of the detection light: If the detection light is not on, it This is a generator fault, and the neutral connecting wire and its terminal may be open circuit; if the detection indicator light is on, it is a line fault, which may be a grounding phenomenon between the neutral point connection line of the regulatore voltage and the generator terminal. When the charging light turns on and off, it may be due to poor thermal stability of the generator's silicon rectifier diode, poor contact between the affected terminals and connectors, or wiring problems. During maintenance, first check whether the generator drive belt is loose. After confirmation, remove the wire from terminal F of the generator and connect the detector indicator light to both ends of terminal B and terminal F. When the motor drives the generator to run at medium speed, observe the working status of the charging indicator light. If the charging light is working properly, repair the voltage regulator or wiring harness. If the charging light is on and off, there are two reasons for the fault: generator failure, which may be caused by the deterioration of the characteristics of the silicon rectifier diode, apoor contact of generator neutral terminal wire, etc. ; breakdown, which can be caused by poor contact of wires, loose connectors, etc. When the wire on armature terminal B is burned, it may be a circuit fault, such as the wire harness being worn by the wire clamp burrs, the wire harness being installed in a wrong position, the wire on the generator armature B terminal touching the engine exhaust manifold, etc. It may also be a generator fault, such as armature B terminal grounding, rectifier diode failure, serious leakage of related components, etc. Specific inspection methods are as follows: 1. Check the generator. During maintenance, remove the wire from generator armature terminal B and connect a tester between the positive pole of the battery and terminal B of the generator. Test the lamp, then observe the luminescence of the test lamp: if the lamptest is slightly brighter, the fault may be leakage at the armature B terminal or poor characteristics of the silicon rectifier diode if the test lamp is on, the fault may be; grounding at armature terminal B or failure of silicon rectifier diode short circuit. 2. Line inspection. First turn off the main switch or remove the positive battery cable connector, remove the wire from the generator terminal B, and connect a detection lamp in series between the positive battery cable connector and the positive terminal of the generator. battery. If the test light is on, it means there is a fault in the circuit. The wire between the generator and the starting battery terminal may be grounded, or it may be that the wire between the starting battery terminal and a switch is plugged in. the power, start and ignition harness is switched ondown.
Why can't the generator turn on if the battery is normal? Just click and nothing happens.
The repair method for a diesel generator that is not producing electricity is:
The main reason why a diesel generator is not producing electricity is because its internal rectifier diode is damaged. After inspection, it is determined where the rectifier diode is damaged and the defective diode can be temporarily cut off. Although this reduces the power output of the generator, the generator can still be used.
This may also be due to the shelf life expiring. Whatever the part, it has a lifespan. Once the service life expires, it will be damaged. This type of damage is inevitable. This is a normal damage and in this case there is no other option than to replace it.
The inability of the generator to produceelectricity is not necessarily a problem in itself. Sometimes the failure of other electrical components can also cause the generator to malfunction, such as unstable current, line failure, etc. such as car lighting systems, dashboards, ignition systems, etc., are some of the problems that can occur in the circuit. At this point, you need to go to a professional 4S store or maintenance office to specifically check where the problem is. Resolve accordingly.
The generator cannot turn on and cannot start:
1. First check if the engine oil and gasoline (diesel) have been added recently. If not newly added, the quantity previously added. exceeds 3 It has been a month and the engine oil and gasoline (diesel) need to be drained and replaced. (Since engine oil and gasoline (diesel) are only validAfter three months, oil and gasoline (diesel) that have been used for more than three months have lost their viscosity and have no effect.
2. engine oil and gasoline used in generators? Fill the tank. If it is not filled, the generator will not ignite or start.
3. fire. If it is not on fire, remove the spark plug. Put gasoline on it and see if the generator is on fire. If it starts, everything will be fine.
