Explain about Starting circuit.

Question

Accepted Answer

The starting circuit is responsible for initiating the engine's operation.

The starting circuit consists of components such as the battery, starter motor, ignition switch, and solenoid.
When the ignition switch is turned on, it sends a signal to the solenoid, which then engages the starter motor.
The starter motor uses electrical energy from the battery to turn the engine's crankshaft, starting the combustion process.
Once the engine starts running, the starter motor disengages from the engine.
If there is a problem with the starting circuit, the engine may fail to start or experience difficulty in starting.

Accepted Answer

The positive line of the battery is connected to fuse which is connected to the 30 numbered pin of open relay and finally the supply from that relay is connected to the alternator. Whereas the negative line of the battery is conneceted directly to alternator forms the closed starting circuit.

After staring switch being ON, the contactor of the relay is connected to to 87 numbered pin with 30 numbered pin( after activating of relay coil). By this the closed circuit is completed and the current starts flow through the alternator. Due to which flywheel starts rotating and in the end the engine starts working.

After cranking, the staring swtich automatically acquires its original position.
