Method for repairing a car generator not producing electricity (brushless generator)

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 the contact is oxidized, resulting in poor contact or connection of the generator system. Causes such as wires andDamaged or defective terminals. 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 thesensor light does not illuminate, remove the wire from the generator neutral point N terminal and observe the sensor light: If the sensor light 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 light is on, it is a line fault, which may be a grounding phenomenon between the neutral point connection line of the regulatorvoltage ator and 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 indicator 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 silic rectifier diodeium, poor contact of the neutral terminal wire of the generator, etc. ; breakdown, which can be caused by poor contact of wires, loose connectors, etc. When the wire on the B armature terminal is burned, it may be a circuit fault, such as the wire harness being worn by the burrs of the wire clamp, 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. When servicing, remove the wire from generator armature terminal B and connect a tester between the positive battery terminal and generator terminal B. Test the lamp, then observe the luminescence of the test lamp : if thetest lamp 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. the 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 ist grounded.

What should I do if the generator cannot start?

There are many reasons why the motorcycle generator is not producing electricity, such as a poor contact in the power path, aging of the ignition coil, or breakdown of the generator itself, etc. Please follow the steps below to check the problem:

1. Check the power path, open the power path, wipe each contact, add a little grease, check the contact situation, if any detachment is found, please repair it immediately. ;

2. Check the ignition coil. Remove the ignition coil and check the voltage with a multimeter. If the ignition coil is old, please replace it with a new one.

3. Check the generator, disassemble the generator and use a multimeter to measure the DC voltage. If the standard voltage value is not reached, it meansthat there is an internal fault in the generator. generator with a new one.

One million car subsidies

The motorcycle's spark plug did not flash and the engine did not turn over. same time. For what?

1. The main reason for the gasoline generator is to check whether the spark plug lights. If there is no ignition, replace the spark plug. Otherwise, you need to check the high voltage assembly. and the engine.

2. The oil nozzle and oil pump of the diesel generator are dirty. Just remove them and clean them with diesel.

3. If there is a problem with the fuel quality (the oil is impure or contains water), simply replace it.

4. The cylinder of gasoline engine and diesel engine is more troublesome. You need to open the cylinder to find out if the component is damaged.

Your description pcould have been inaccurate. If the generator is not running, the spark plug will definitely not fire. running out of water? Lights, horns, etc. cannot determine if the battery is discharged. Compared to electric starters, horns and lights use very little power. If you do not ride a motorcycle for a long time, the battery may lose power or even be discarded. You should try charging it with a charger. If it still cannot be used after charging, you need to replace it. battery. If there is a kick starter, remove the spark plug and squeeze the kick starter lever a few more times to drain any excess oil in the cylinder. If the motorcycle is not used for a long time, the gasoline in the carburetor can evaporate and deteriorate, forming a sticky substance that blocks the carburetor nozzle holes and makes it impossible to start.age. Therefore, the carburetor must be removed and cleaned carefully. to carefully clean all the different parts of the carburetor. The nozzle holes and gasoline in the fuel tank must be replaced if they deteriorate. If it was normal before parking, after parking there are usually no major problems. The starter, electrical components and other engine components are basically undamaged. However, the battery is prone to loss of power and the carburetor tends to clog. If the starter motor still does not turn after charging or replacing the battery, check for problems with the circuits, whether the starter motor is rusty or stuck after a long period of disuse, etc.
