Fault causes and troubleshooting of car ignition system

fault causes and troubleshooting of Santana car ignition system:

what are the reasons for the error of the pressure testing machine caused by the traditional contact type of Santana car before december1985. Since december1985, Santana car has adopted a contactless transistor ignition system with Hall element as sensor. The output signal of the sensor is very small, which eliminates the traditional method of closing and separating the breaker contact by the distributor cam, and replaces it with the trigger rotor, the reactor sensor and the crystal ignition control device. The main common fault of ignition system is that the engine can not start in order to eliminate confusion. The phenomenon is that when the ignition switch is turned to the start position, the starter runs and the engine cannot start

fault cause:

1 Loose wire connection and poor contact

2. Ignition coil winding is open circuit or grounded

3. Ignition controller failure

4. The hall sensor is damaged

5. The distributor cover and the fire distributing room are broken and leaked

6. The spark plug gap increases, the ablation is serious, and there is too much oil and carbon deposit

7. High voltage wire resistance is too high

the troubleshooting methods for ignition are as follows

if the starter runs, it indicates that the battery and starter are of good technology. The reason why the engine can not start and the experimental data of multiple samples in the same group can be counted is the ignition system or oil supply system. Valve inlet pump

1 Visually inspect the wires or harness connectors for looseness. If the wire is loose, tighten or firmly insert the connector to make the wire contact well. If the wire is not loose, check the spark generating capacity of the ignition coil

2. Remove the central high-voltage line from the power distributor cover, clamp the high-voltage line with insulating pliers, and make its end 6-7mm away from the engine. Start the engine. If there is a blue spark at the end of the high-voltage line, it indicates that the low-voltage circuit is in good condition. If the fault is in the high-voltage circuit, check the distributor cover, distributor, high-voltage wire and spark plug. If there is no spark at the high-voltage line end, it indicates that the low-voltage circuit is faulty. Check the ignition coil, transistor controller and Hall sensor
