After the start switch is turned on, the automobile starter makes a continuous clicking sound. If the two main terminals of the electromagnetic switch of the automobile starter are short-circuited and the starter rotates normally, the electromagnetic switch is to keep the coil short-circuited or open-circuited. Wires can be connected to two terminals of the automobile starter switch. If the speed of automobile starter is obviously accelerated, it means that the starter switch is in poor contact and the resistance is increased. If the speed of the automobile starter remains unchanged, it is necessary to confirm whether the battery is fully charged. Whether the brush wear is too large and whether the brush spring is too weak. The local short circuit of armature coil or magnetic field coil in automobile starter is also one of the reasons for the weakness of starter. You can carefully touch the starting circuit leads and connectors. If there is no spare fuse or relay, other substitutes can be used. If the wiper cannot be used in sunny days, the fuse and relay of the wiper can be removed and installed at the position of the gasoline pump.
The internal machine failure of automobile starter will also affect the normal work of starter. When the power start circuit and start switch are in good condition, check whether the starter bearing is too tight. Whether the armature bends or not is due to the friction between the armature and the magnetic pole. The failure of the car to start is the most common fault we encounter. There are many reasons for this failure. Such as battery loss, power failure, fuel system failure, engine mechanical failure, etc. The starter is slow and weak, and the engine can't reach the starting speed, which is generally caused by battery loss. At this time, it is best to use other batteries to generate electricity. You can also use the emergency start power of that car to help start. If these conditions are not met, you can rearrange the connection line between the battery electrode and the engine ground wire and try again. If it still doesn't start, you must use other batteries to generate electricity.
If you press the start button or twist the key door, the car doesn't respond, which is usually a fault in the starter circuit. We ordinary people are incapable of finding circuit faults. At this time, we must first make sure that the fuse of the power box is not broken. If it is replaced, we will start it urgently. We can get close contact with the drama and magnetic switch of the starter, and then we can start the engine as long as it is not the fault of the starter itself. The starter works normally and the rotation speed is high enough, but if the engine can't start, it is necessary to consider whether the fuel system is faulty. When the ignition switch is turned on, there is a buzz in the fuel tank. Otherwise, when the gasoline pump can't work normally, the safety or relay of the gasoline pump mostly fails.
