Maintenance of alternator

1. Disassembly of alternator

2. Inspection of main components of alternator

(1) Inspection and adjustment of V-belt tightness

(2) Inspection and replacement of brush

(3) Inspection of rotor

a. Measurement of field winding resistance

b. Inspection of insulation between field winding and rotor shaft

(4) Inspection of stator winding

a. Inspection of stator winding resistance

b. Inspection of insulation resistance between stator winding and stator core

(5) Inspection of silicon diode

3. Alternator assembly

4. Non disassembly detection of alternator: measure the resistance between each terminal of the generator.

Inspection of regulator

(1) Inspection of ft61 regulator

(2) Inspection of transistor regulator

a. Check with test lamp and DC regulated power supply

b. Check with a multimeter

Power system circuit

1、 Charging indicator control circuit

1. Using neutral point voltage to control through charging indication relay: Taking the control of Toyota generator regulator (with relay) as an example

2. Controlled by nine tube generator

2、 Power system circuits of several vehicle models

1. Power circuit

2. Chery power system circuit

(1) First he excitation

Excitation circuit: battery positive pole → P → 30# → 15# → charging indicator lamp → a16 → D4 → T1 → generator D terminal → excitation winding → regulator → grounding → battery negative pole.

(2) Post self excitation

Excitation circuit: terminal D → excitation winding → regulator → grounding → generator negative pole.

Correct use of generator and regulator and basic methods of fault diagnosis

1、 Correct use of alternator

2、 Correct use of regulator

3、 Basic methods of power system fault diagnosis

1. Charging indicator diagnosis

2. Diagnosis with voltmeter

3. Diagnosis of no-load and load performance

Common troubleshooting of power system

1、 No charging

(1) Fault phenomenon

(2) Diagnostic procedure

2、 Charging current is too small

3、 Excessive charging current

4、 Common fault parts of alternator charging system

Computer controlled voltage regulating circuit and overvoltage protection circuit

1、 Computer voltage regulating circuit

This system provides current pulses to the excitation winding at a fixed frequency of 400 pulses per second, and changes the average value of excitation current by changing the on and off time, so as to make the generator output appropriate voltage.

2、 Overvoltage protection circuit: most of them are voltage stabilizing tube protection circuits.
