Maintenance Of Starting System
1. Correct use
Since the current of the starter can reach several hundred amperes, continuous long-term starting will generate a lot of heat, which is easy to burn the motor insulation and cause a short circuit. Therefore, you should pay attention to:
(1) The starting time should be as short as possible. The starting time should not exceed 5s each time. If it fails to start for the first time, it should stop for 10-15s before starting the second time.
(2) When the battery is running out of power or starting at low temperature in winter, the engine and battery should be preheated, and the engine should be "cranked" before starting.
2. Correct maintenance
The working time of the starter is short, and the frequency of its use determines the maintenance interval mileage. The maintenance workload required in general use is not large. If maintenance is required, the following points should be noted:
(1) Always keep the outside of the starter clean and ensure that the connecting wires are firmly connected.
(2) Pay attention to check whether the battery is fully charged.
(3) Every 5000-6000 km of the car, the wear of the brush and the spring elasticity should be checked, and it should be replaced in time when it is found that it does not meet the standard.
(4) Regularly check the bearing lubrication of the starter. [4]
Reason and Check
(1) The starter does not start or the starting operation is weak.
Causes of failure: serious power loss of battery; poor contact of starter circuit; poor contact of starter switch; short circuit, open circuit or grounding of starter excitation winding or armature winding; poor contact between brush and rectifier; short circuit or open circuit of electromagnetic switch coil; The control circuit is faulty.
Troubleshooting:
1) First check the battery level. The method is to turn on the headlights or honk the horn, the lights are bright and the horn is loud, indicating that the battery is normal, otherwise the battery is faulty.
2) Check whether the motor part of the starter operates normally. Short-circuit the starter switch terminal, and use the spark strength at the moment of short-circuit to judge the fault. Strong sparks indicate that there is grounding inside the starter, and weak sparks indicate poor internal contact.
3) Check the electromagnetic switch. Short the terminal on the solenoid switch to the terminal on the ignition switch. If the starter runs weakly, it means that the ignition switch is in poor contact; if the spark is too strong or too weak when the terminal is shorted, it means that the coil is grounded or broken.
4) Check the starting additional breaker. First, short-circuit the power terminal and the motor terminal. If the starter can start, it means that the connection between the box motor and the relay is normal. Then short-circuit the power terminal and the ignition switch terminal. If the starter can start, the relay is normal, and the fault lies in the ignition switch. on the circuit. If you hear a "click" sound inside it during short-circuiting, it means that the contact is ablated and the contact is poor; if there is no sound, it means that the line is open or there is an open circuit on the corresponding circuit.
(2) There is a strong sound of gear teeth hitting when the engine is started.
cause of issue:
1) Engine flywheel ring gear and starter pinion are seriously worn.
2) Improper adjustment of the starter switch.
Troubleshooting:
1) Adjust the starter switch and fork connection mechanism.
2) Remove the starter and check the engine flywheel ring gear and starter pinion.
(3) The starter idles at high speed when the engine is started.
Cause of failure: The one-way clutch parts of the starter slips.
(4) There is a crash sound inside the starter when the engine is started.
cause of issue:
1) The starter shaft is bent.
2) The starter shaft is seriously worn.
3) The magnetic pole of the starter is loose.
4) The starter motor armature coil falls off.
