Cara Kerja Sistem Starter pada Sepeda Motor Matik

Summary

In this video, the presenter explains the operation of the starter system in automatic motorcycles, using a common motorcycle model as an example. Key components such as the battery, fuses, ignition switch, starter button, and electromagnetic relay are outlined. The flow of electrical current is described, emphasizing the importance of engaging the brake lever and side stand for the system to function. The video highlights potential issues that can prevent the starter from engaging, such as weak battery voltage or broken components, providing viewers with a comprehensive understanding of how to troubleshoot starter problems in automatic motorcycles.

Takeaways

• 😀 The video explains the working of the starter system on a scooter (moped).
• 😀 The key components of the system include the battery, fuse, ignition switch, starter button, bendix relay, starter motor, stand switch, and brake light switch.
• 😀 When the ignition switch is turned on, and the brake lever is pulled, electrical current flows from the battery through the fuse and ignition switch to the brake switch.
• 😀 The brake light illuminates when the brake lever is pulled, completing the circuit for the starter system to function.
• 😀 The current then flows to the starter button, which activates the bendix relay, allowing current to flow to the starter motor.
• 😀 The starter motor rotates the crankshaft, which in turn operates the engine's internal components.
• 😀 The system relies on the electromagnetism in the bendix relay to complete the connection, allowing the starter motor to work.
• 😀 The system will not work if the brake lever is not pulled, as the current cannot reach the bendix relay to activate the starter motor.
• 😀 Similarly, the stand switch must be in the 'up' position for the current to flow, allowing the starter motor to function.
• 😀 If any part of the system, such as the fuse, brake switch, or wiring, is faulty or disconnected, the starter motor will not work and needs to be repaired.

Q & A

What is the purpose of the starter system in a scooter?

The starter system in a scooter is designed to initiate the engine's operation, enabling the motor to start running when the rider activates the system.

What components are involved in the starter system of a scooter?

The components involved in the starter system include the battery (aki), fuse (sekering), ignition switch (kunci kontak), starter button (tombol starter), starter relay (bendik), starter motor (motor starter), side stand switch (stand switch), and brake light switches (lampu rem).

How does the starter system work when the ignition key is turned on?

When the ignition key is turned on, electrical current flows from the battery through the fuse, ignition switch, brake light switch, and starter button, completing the circuit to activate the starter motor.

What role does the brake light switch play in the starter system?

The brake light switch ensures that the starter system only operates when the brake lever is pulled. This safety feature prevents the scooter from starting if the brake is not engaged.

What happens when the side stand is in the down position?

If the side stand is in the down position, the starter system will not engage, preventing the engine from starting. This is a safety feature to avoid accidental movement of the scooter.

What is the function of the starter relay (bendik) in the system?

The starter relay (bendik) uses electromagnetic force to connect the electrical circuit, allowing current to flow from the battery to the starter motor, which then starts the engine.

What happens if the brake lever is not pulled before starting the scooter?

If the brake lever is not pulled, the brake light will not illuminate, and the starter system will not receive power. As a result, the engine will not start.

Why is it important for the fuse, ignition switch, and brake light switch to be in good condition?

If any of these components fail (like a blown fuse or a faulty switch), the electrical circuit will be incomplete, and the starter motor will not receive power, preventing the engine from starting.

How does the starter motor operate to start the engine?

When the starter relay is activated, it sends current to the starter motor, which turns the engine's crankshaft, enabling the engine to start running.

What should be checked if the starter motor does not spin?

If the starter motor does not spin, it could be due to weak battery voltage, a blown fuse, a damaged ignition switch, or a malfunctioning brake lever switch. These factors should be checked one by one to diagnose the issue.
