Yamaha motorcycles are known for their high performance and reliability. If you want your Yamaha motorcycle to run smoothly, it is essential to have a good understanding of its starter relay wiring diagram. In this article, we will discuss the Yamaha starter relay wiring diagram in detail, including its various components, how it works, and troubleshooting tips.
What is a Starter Relay?
A starter relay is an electrical device that is used to start an engine. It is also known as a starter solenoid. The starter relay is located on the motorcycle’s starter motor or battery. Its primary function is to engage the starter motor by sending an electrical current to it.
The starter relay consists of several components, including a coil, plunger, contact switch, and terminals. These components work together to enable the starter motor to start the engine.
Components of a Starter Relay
1. Coil: The coil is the primary component of the starter relay. It is an electromagnet that generates a magnetic field when an electrical current is applied to it. The coil is generally made of copper wire and is wrapped around an iron core.
2. Plunger: The plunger is a movable component of the starter relay. It is made of iron or steel and is located inside the coil. When an electrical current is applied to the coil, the plunger is pulled into the coil by the magnetic field created by the coil.
3. Contact switch: The contact switch is located on the top of the plunger. When the plunger is pulled into the coil, the contact switch makes a connection between the battery and the starter motor. This connection sends an electrical current to the starter motor, which starts the engine.
4. Terminals: The terminals are located on the bottom of the starter relay. They provide a connection between the starter relay and the motorcycle’s electrical system.
Yamaha Starter Relay Wiring Diagram
The Yamaha starter relay wiring diagram is a schematic representation of the electrical connections between the starter relay, battery, starter motor, and other components of the motorcycle’s electrical system. It is essential to have a good understanding of the wiring diagram to troubleshoot any electrical issues that may occur.
How to Read a Wiring Diagram
A wiring diagram consists of several symbols and lines that represent electrical connections. The symbols and lines represent different electrical components and their connections. The following are some of the most common symbols used in a wiring diagram:
| Symbol | Function |
|---|---|
| Battery | Provides power to the electrical system |
| Starter motor | Engages the engine to start |
| Starter relay | Engages the starter motor by sending an electrical current to it |
| Coil | Generates a magnetic field when an electrical current is applied to it |
| Plunger | Movable component of the starter relay that makes a connection between the battery and starter motor |
The lines in a wiring diagram represent the electrical connections between the components. The lines are labeled with numbers and letters that correspond to the component’s terminals. The numbers and letters help to identify the connections between the components and their function.
Yamaha Starter Relay Wiring Diagram: Components and Connections
The Yamaha starter relay wiring diagram consists of several components and their connections. The following are the components and their connections:
1. Battery: The battery provides power to the electrical system. The positive terminal of the battery is connected to the starter relay’s terminal 30, and the negative terminal is connected to the motorcycle’s chassis ground.
2. Starter relay: The starter relay is connected to the battery’s positive terminal through terminal 30. Terminal 85 is connected to the motorcycle’s chassis ground, and terminal 86 is connected to the starter switch. Terminal 87 is connected to the starter motor.
3. Starter switch: The starter switch is connected to the starter relay’s terminal 86. When the starter switch is pressed, it sends an electrical current to the starter relay’s coil, which pulls the plunger into the coil, making a connection between the battery and the starter motor.
4. Starter motor: The starter motor is connected to the starter relay’s terminal 87. When the starter relay makes a connection between the battery and the starter motor, it sends an electrical current to the starter motor, which engages the engine to start.
Troubleshooting Tips
If your Yamaha motorcycle is not starting, the starter relay may be faulty. The following are some troubleshooting tips:
Check the Battery
The first step in troubleshooting any electrical issue is checking the battery. Make sure that the battery is fully charged and has no loose or corroded connections.
Check the Starter Relay
If the battery is okay, the next step is to check the starter relay. You can do this by using a multimeter to test the starter relay’s resistance. If the resistance is outside the manufacturer’s specifications, the starter relay may be faulty and need to be replaced.
Check the Starter Motor
If the starter relay is okay, the next step is to check the starter motor. You can do this by checking its resistance with a multimeter. If the resistance is outside the manufacturer’s specifications, the starter motor may be faulty and need to be replaced.
Conclusion
The Yamaha starter relay wiring diagram is an essential component of the motorcycle’s electrical system. It is essential to have a good understanding of the wiring diagram to troubleshoot any electrical issues that may occur. By following the tips discussed in this article, you can ensure that your Yamaha motorcycle starts smoothly and runs reliably.
