Methods for checking faults of silicon rectifier alternator charging circuit:
1. If the silicon rectifier alternator belt is loose, slipping and worn, these conditions will reduce the power output of the silicon rectifier alternator and cause damage. the engine is malfunctioning. The water temperature is too high.
2. Check for noise. Noise is caused by improper motor installation, damaged bearings, bent shaft or broken carbon brushes; shorted or broken.
Turn the silicon rectifier alternator pulley by hand to see if the armature shaft rotates flexibly. Or check when the silicon rectifier alternator is working and gradually increase the engine throttle to see if there is any abnormal noise. When the V-belt makes abnormal noise and is worn during operation, check whether the crankshaft pulley, poThe water pump pulley and the silicon rectifier generator pulley are in the same plane.
3. Wire connection conditions. A connection failure will prevent the silicon rectifier alternator from producing electricity or producing electricity that does not meet requirements.
Use the voltage or ohm scale of the multimeter to check whether the connecting parts of the wire ends between the silicon rectifier alternator, regulator and ammeter are correct and whether the fuse is toasted; silicon rectifier alternator (B+) Spring washers must be added to the connection terminals; For silicon rectifier alternators connected by plug-in connectors, the connection between the socket and the line plug should be locked and there should be no play.
4. Check the silicon rectifier alternator.
Touch the positive “+” terminal of the voltmeter to the “armature” terminal (B+) ofthe silicon rectifier alternator. Touch the negative “-” of the voltmeter on the shell of the silicon alternator rectifier. When the silicon rectifier alternator is not rotating, the voltage indication value is the battery voltage (reference voltage). If the speed of the silicon rectifier alternator increases and the voltmeter shows the original value, it means the silicon rectifier alternator is defective.
What are the connection methods for the three-phase stator winding of a silicon rectifier generator?
JF151A is an ordinary alternator without a built-in regulator, so you need to purchase a regulator.
"+" is connected to the battery
"—" is connected to ground
"N" is connected to the 6V relay, you do not not you have to connect it if you don't need it
"F" is connected to the F of the regulator
1. Star connection, star connection - that is, connect all threeends. of the generator winding together as a common end and bringing out three wires from the first three ends using the Firewire connection method.
2. Angular connection. This is a connection method in which the start and end of each phase of the generator winding are connected in sequence. (For example, the load of phase A is represented by Ax, the load of phase B is represented by By and the load of phase C is represented by Cz, that is, x is connected to B , y is connected to C, z is connected to A and the three lines drawn are Bx, Cy and Az.) The voltage carried by each phase load is the line voltage of 380 volts, i.e. the tension between the live wire and the live wire.
