If you’re looking for information on the wiring diagram for your Yamaha outboard ignition switch, you’ve come to the right place. In this article, we’ll cover everything you need to know about the wiring diagram for your outboard ignition switch, including the different wires and their functions, and how to troubleshoot any issues. So let’s get started!
The Yamaha Outboard Ignition Switch: Functions and Wiring Diagram
The Yamaha outboard ignition switch serves several key functions, including turning on the engine, controlling the choke, and activating the emergency stop switch. The wiring diagram for your ignition switch will vary depending on the model of your Yamaha outboard motor, but the basic wiring principles remain the same.
The ignition switch is typically located on the control box or the dashboard of your boat, and it’s connected to a number of different wires that control various functions. These wires include:
| Wire Color | Function |
|---|---|
| Red | Positive Battery Terminal |
| Black | Ground |
| Yellow | Ignition/Lanyard Stop Switch |
| Green | Tachometer Signal |
| Blue | Choke Signal |
The wiring of these wires is crucial to the proper functioning of your Yamaha outboard ignition switch. Below, we’ll cover the different functions of each wire and how to troubleshoot any issues you may be experiencing.
The Red Wire: Positive Battery Terminal
The red wire on your Yamaha outboard ignition switch is connected to the positive battery terminal. This wire provides power to the ignition switch and helps to start the engine. If you’re experiencing issues with your ignition switch, the first thing you should check is the red wire to ensure it’s properly connected to the battery terminal.
If the red wire is properly connected, but you’re still experiencing issues with your ignition switch, you may want to check the battery itself. Make sure it’s fully charged and that the terminals are clean and free of corrosion.
The Black Wire: Ground
The black wire on your Yamaha outboard ignition switch is connected to the ground. This wire helps to complete the circuit and ensure that the engine starts properly. If you’re experiencing issues with your ignition switch, check to make sure the black wire is properly grounded.
If the black wire is properly grounded, but you’re still having issues, you may want to check the ignition switch itself. Make sure it’s properly aligned and that the contacts are clean and free of debris.
The Yellow Wire: Ignition/Lanyard Stop Switch
The yellow wire on your Yamaha outboard ignition switch is connected to the ignition and lanyard stop switch. This wire helps to control the engine speed and ensure that the engine is running properly. If you’re experiencing issues with your ignition switch, check to make sure the yellow wire is properly connected.
If the yellow wire is properly connected, but you’re still having issues, you may want to check the ignition and lanyard stop switch itself. Make sure it’s properly positioned and that the contacts are clean and free of debris.
The Green Wire: Tachometer Signal
The green wire on your Yamaha outboard ignition switch is connected to the tachometer signal. This wire helps to measure the engine speed and ensure that the engine is running at the proper RPM. If you’re experiencing issues with your tachometer, check to make sure the green wire is properly connected.
If the green wire is properly connected, but you’re still having issues with your tachometer, you may want to check the tachometer itself. Make sure it’s properly calibrated and that the connections are clean and free of debris.
The Blue Wire: Choke Signal
The blue wire on your Yamaha outboard ignition switch is connected to the choke signal. This wire helps to control the choke and ensure that the engine starts properly, especially in colder weather. If you’re experiencing issues with your choke, check to make sure the blue wire is properly connected.
If the blue wire is properly connected, but you’re still having issues with your choke, you may want to check the choke itself. Make sure it’s properly positioned and that the connections are clean and free of debris.
