Yamaha 6Y5 gauges are part of the company’s Command Link Plus system. They provide boaters with important information about their vessel’s performance and can warn of potential problems. Proper wiring is essential to ensure accurate readings and efficient operation. In this article, we’ll provide a detailed Yamaha 6Y5 gauge wiring diagram along with some commonly asked questions and helpful tips.
Wiring Diagram
Before we get started with the wiring diagram, it’s important to note that the wires on your boat may not match those in the diagram due to different color codes or custom installations. Always refer to your owner’s manual or consult with a professional if you are unsure about any aspect of the installation.
| Wire color | Function |
|---|---|
| Red | 12V Power Supply (Battery Positive) |
| Black | 12V Ground |
| Light Blue | Instrument Lighting |
| Brown | Tachometer Signal |
| Yellow | Speedometer Signal |
| White/Black Stripe | Fuel Level Signal |
| Gray | Water Pressure Signal |
Now let’s break down each wire’s function:
Red Wire:
The red wire provides power supply from the battery to the gauge. It should be connected to the positive (+) battery terminal.
Black Wire:
The black wire is the ground wire and should be connected to the negative (-) battery terminal.
Light Blue Wire:
The light blue wire is responsible for illuminating the gauge. It should be connected to the boat’s lighting circuit so that the gauge lights up when the boat’s lights are turned on.
Brown Wire:
The brown wire is the tachometer signal wire. It should be connected to the boat’s ignition coil or tachometer output signal wire. This wire is responsible for providing the tachometer with information about the engine’s RPM.
Yellow Wire:
The yellow wire is the speedometer signal wire. It should be connected to the boat’s speed sensor or pitot tube. This wire is responsible for providing the speedometer with information about the boat’s speed.
White/Black Stripe Wire:
The white/black stripe wire is the fuel level signal wire. It should be connected to the boat’s fuel sender or fuel level gauge. This wire is responsible for providing the fuel gauge with information about the fuel level in the tank.
Gray Wire:
The gray wire is the water pressure signal wire. It should be connected to the boat’s water pressure sensor or water pressure gauge. This wire is responsible for providing the water pressure gauge with information about the engine’s water pressure.
Frequently Asked Questions
1. Can I use a different wire color than what is specified in the diagram?
While it is recommended to use the wire colors specified in the diagram, you can use different colors as long as you are consistent with your connections and label each wire accordingly. This will help avoid confusion or issues down the road.
2. Do I need any special tools to install the gauges?
Basic hand tools such as screwdrivers, pliers, and wire strippers will be required to install the gauges. A multimeter may also be helpful for testing connections and troubleshooting any issues that may arise.
3. How do I know if my gauges are working properly?
Once the gauges are installed and wired correctly, turn on the boat’s power supply and verify that each gauge is functioning properly. Check that the readings on each gauge match what you would expect based on the boat’s performance. If you notice any discrepancies or abnormal readings, refer to the owner’s manual or consult with a professional.
4. How can I troubleshoot any issues with my gauges?
If you are experiencing issues with your gauges, start by checking the connections and wiring to make sure everything is securely connected and there are no loose or damaged wires. You can also use a multimeter to check voltage and resistance at various points in the wiring. If you are unable to diagnose or fix the issue on your own, consult with a professional.
