This is a three-phase alternator. Use a multimeter to measure the resistance of the four terminals to distinguish which one is the neutral line (the red test lead is connected to the neutral line, and the black test lead is connected to the neutral line. The wire measures the other three. If the resistance values of the two wires are the same, the red test lead is the neutral wire and the other three wires are the live wires.)
There are two ways to connect: one consists of using a live wire and a neutral wire. The diode charges the 12-volt battery; the other is to use threes live wires connected to a three-phase bridge rectifier to produce 12 volts DC to charge the battery. .
In addition, you can also use a live wire and a neutral wire to directly connect the car headlights for lighting purposes.
How to wire the generator of Dongfanghong 1002 bulldozer
This is a three-phase alternator. Use a multimeter to measure the resistance of all four terminals to distinguish which one is the neutral line. (The red test lead is connected to the neutral wire. If the black test lead measures the same resistance value as the other three wires, the red test lead is the neutral wire and the other three wires are the live wires. )
There are two ways to connect: one is to use a live wire and a neutral wire connected to a diode to charge the 12 volt battery; the other is to use three live wires connected to a three-phase rectifier; louse bridger produce 12 volts DC to charge the battery.
In addition, you can also use a live wire and a neutral wire to directly connect the car headlights for lighting purposes.
1. Connect the three ends of the generator winding of Dongfanghong 1002 bulldozer together as a common terminal.
2. The method of connecting 3 live wires drawn from 3 network heads. (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, y and z are connected together to conduct three-wire A, B and C.) The voltage supported by each phase coil of the load is 220 volts, that is, the voltage between the live wire and the neutral wire (neutral wire) is 220 V.
3. Connect the three lines according to the instructions.
