Yamaha is a well-known manufacturer of high-quality marine equipment, and their multifunction gauge is a popular choice for many boat owners. The multifunction gauge is designed to provide boat owners with a range of information, including engine speed, water temperature, and fuel level. In this article, we will take a closer look at the Yamaha multifunction gauge wiring diagram and provide you with a comprehensive guide on how to install and wire the gauge in your boat.
What is a Yamaha Multifunction Gauge?
A Yamaha multifunction gauge is a device that can display a range of information relating to your boat and its performance. The gauge is designed to work with Yamaha outboard engines, and it can display information such as engine speed, water temperature, oil pressure, and fuel level. The Yamaha multifunction gauge is highly configurable, and it can be adjusted to display the information that is most important to you.
The Yamaha multifunction gauge is available in several different configurations, and it can be purchased with or without a GPS receiver. The GPS receiver allows the gauge to display your boat’s speed and location, making it a valuable tool for navigation.
Wiring the Yamaha Multifunction Gauge
The Yamaha multifunction gauge wiring diagram is relatively simple, but it is important to follow the wiring diagram carefully to ensure that the gauge functions correctly. The Yamaha multifunction gauge consists of four wires:
| Wire Color | Function |
|---|---|
| Red | Power (+12V) |
| Black | Ground |
| Yellow | Serial Data |
| Green | Serial Clock |
When wiring the Yamaha multifunction gauge, it is important to ensure that the wiring is done correctly. The wiring diagram will differ depending on the configuration of your gauge, so it is important to refer to the wiring diagram that is specific to your gauge.
Power (+12V) Wiring
The red wire of the Yamaha multifunction gauge should be connected to a positive (+12V) power source. This power source should be connected directly to the battery to ensure that the gauge remains powered even when the ignition is turned off.
It is important to fuse the power wire to protect the gauge and the boat’s electrical system. The fuse should be located as close to the battery as possible.
Ground Wiring
The black wire of the Yamaha multifunction gauge should be connected to a suitable ground point on the boat. The ground point should be as close to the gauge as possible and should be connected to the boat’s main ground bus.
Serial Data Wiring
The yellow wire of the Yamaha multifunction gauge should be connected to the engine’s primary data cable. This cable is usually located near the engine’s ECU and is a 4-pin connector. The yellow wire should be connected to the data pin of this cable.
Serial Clock Wiring
The green wire of the Yamaha multifunction gauge should be connected to the engine’s primary data cable. This cable is usually located near the engine’s ECU and is a 4-pin connector. The green wire should be connected to the clock pin of this cable.
