Starting system, starting motor

An initiator is an electric motor that powers the motor or “crank” to start the motor. It consists of a powerful electric motor (DC) and a primary solenoid connected to the motor
The starter  motor is powered by the car’s battery To start the engine The starting motor requires a very high electrical current which means the battery must have enough power.
Problems with the starting system are common, and most problems do not occur due to the starting system and to be sure of this, the starting system must be tested first.
start-up file

The solenoid in the starter system acts as a transmission of electrical power. When activated, the circuit is closed and battery power is sent to the motor. At the same time, the solenoid drives the start gear to be engaged in the flywheel.
The solenoid contains a small conductor for the control wire, and also contains two wires for connecting to the car battery, one connected to the battery and the other to the starting motor.
Battery Cables
The starter motor needs very high voltage, so the battery connection wires are thick enough to withstand the voltage through them from the battery to the motor.
How does the starter system work
When the ignition switch is turned on the start position, the battery voltage is transmitted through the primary control circuit and the solenoid is activated, which activates the motor.
Safety switch
For safety reasons, the starting motor can only be started when the automatic transmission is in the stop or park position, and if the vehicle has a manual transmission when the clutch pedal is depressed.
To achieve this, there is a neutral safety switch installed in the automatic transmission mechanism or on the clutch pedal in the case of manual transmission.
The gear shift sensor is usually the vehicle’s safety switch, which tells the control unit which position the vehicle is in.
When the automatic transmission is in the PARK or PARK position, and in the manual transmission, the clutch is decompressed, the safety switch is actuated and the starting moto is free and uninterrupted.
Problems with the starter system
When you try to start the car, it is normal to hear a sound, which is the sound of the flywheel interlocking with the primary gear and then the engine running, but the problem is when you hear the sound and the engine does not rotate.
