The cause and diagnosis of idling starter are as follows: The phenomenon of idling starter When the starter switch is on, the starter is idling and the pinion cannot engage with the flywheel gear ring to drive the engine. Cause of idling starter 1. The shift fork of the starter is out of slot by mechanical force, and the drive pinion cannot be pushed, or its stroke is improperly adjusted and cannot engage with ring gear. 2. Travel of the solenoid switch iron core is too short. 3. The armature of starter auxiliary circuit has short circuit or open circuit, the armature can not get into its working position. 4. The overrunning clutch of starter slips. 5. Flywheel gear are badly worn or broken. The starter idling fault diagnosis - there are two cases when a starter idles

Nowadays, the gear reduction starter has been widely used in all kinds of vehicles, and its significant advantages have gradually replaced direct drive starter. A reduction type starter, wherein an idler shaft is mounted in a starter housing in parallel with a motor shaft and a pinion drive shaft, and an over running clutch is provided on the idler shaft so that a reduction of rotational speed can be performed at two stages.

This sound caused by the alternator belt aging. Alternator belt is rubber, it is influenced by expansion and contraction. The belt will lengthen in daily use, it will contract and slip in cold state, resulting in a rattling sound. When the engine has heated after running for a few minutes, the belt will be normal and has no rattling sound. The problem is easy to eliminate, replace a new alternator belt.

Some batteries will become very large after the use of old internal resistance, there will be a charge on the full, a release on the end of the phenomenon. Car owners in the battery life cycle of about two and a half years, routine maintenance should test the battery, which can play a preventive role.

This article mainly analyzes the components, circuit diagram and fault diagnosis of modern automobile engine starting system. Modern automobile engine starting system is basically similar. It is of great significance for mechanic to master the relevant knowledge and fault diagnosis process of starting system. The car starting system component. The engine start needs external forces. In order to make the engine transition from static to idle working state, the engine crankshaft flywheel assembly must be rotated by external forces to make the combustible mixture burn in the engine cylinder, so that the engine working cycle can proceed smoothly. The whole process of engine crankshaft flywheel assembly running from rest to idle under the action of external forces is called engine start. Automobile engine starting system is generally composed of battery, ignition switch, starter relay, starter safety switch, starter motor, starter cable, grounding cable and other circuit.

At present, most modern cars are electrical starting system, automotive circuit failure in the starting system has been very common. However, the reasons for the circuit failure of the vehicle starting system are very complex, and the failure occurs in many different parts, which brings us difficulties in the detection and diagnosis of the vehicle starting system. In order to further improve the diagnosis and elimination of circuit failure ability, it is necessary to accurately grasp the starting system circuit diagram, so as to correct and troubleshoot the starting system fault, let's understand the car starting system faults analysis. Automobile starting system components In order to respond quickly to the failure of the car starting system, it is necessary to know the car’s starting system components. The starting system of automobile is made of the accumulator(battery), starter relay, ignition switch and starter. In the starting system, any device is necessary, the car can start normally by these devices. The working principle of the starting system is very simple, first turn on the circuit equipment on the battery through the starter switch, so that the battery quickly generate electrical energy, and then through the ignition switch and start the starter, let the battery's electrical energy into mechanical energy, and generate the energy needed to start the system.

The engine start is the whole process of the engine crankshaft turning from the beginning to the automatic idle operation under the action of external forces. There are many ways to start an engine, such as manual start, electric start, auxiliary gasoline engine start and so on. The engine start are usually powered by starter motor, which are used as mechanical power. When the gear on the starter motor meshed with the gear ring of the engine flywheel, the power of the starter motor is transmitted to the flywheel and crankshaft.

There is a clicking noise when you turn the key, the engine cannot ignite. The clicking noise is the working noise of the relay or the starter motor, indicating the starter motor has responded to the action, but it is unable to drive the flywheel rotation, so it cannot start the car. So what do you do when turn the key, if there is a clicking noise, the engine cannot start and how do you handle this problem?

The interference amount of the flywheel gear ring is too small, and the gear ring rotates on the flywheel. In this case, anti-rotation screws should be added or new tooth rings should be replaced and interference should be checked to see if it is in accordance with the regulations. If the starter gear cannot engage with the flywheel gear ring, check the timing of adjusting the travel of the meshing gear or the magnetic switch to turn on the power.
