Understanding the Fundamentals of Evinrude Tachometer Wiring Diagram


A tachometer is a key piece of equipment when it comes to controlling and monitoring an engine’s performance. Installing a tachometer requires some wiring skill to make connections between the vehicle and the tachometer. Evinrude makes several different tachometer models for its marine engines, and it’s important to understand how to properly wire a tachometer to the engine in order to ensure accurate readings.


Evinrude’s tachometers are equipped with a wiring diagram printed on the back of each unit that helps boat owners understand exactly how to connect their tachometer to the engine and other related devices. These diagrams provide detailed schematics that make it easy to understand how the different wires relate to each other and which wires do what. Once the wiring diagram is understood, boat owners can be sure they have everything connected correctly and safely.



Overview of Evinrude Tachometer Wiring


The term ‘wiring’ refers to the physical connections of cables and wires that are used to make up the electric side of a boat’s engine. This includes both the power and signal cables that help manage the operation of the motor. With Evinrude tachometers, the wiring diagram will typically list the relevant numbers and colors of the wires that need to be connected to the tachometer.



Connecting the Battery to the Tachometer


The first step in wiring a tachometer to an Evinrude motor is to make sure the tachometer is properly connected to a 12-volt battery. This battery should be located as close as possible to the tachometer, making sure to keep the wires away from any moving parts. The wire should be either red or black, depending on the brand, with the + sign denoting the positive end and the - sign the negative end.



Wiring Ignition Switch and Coils


Once the battery has been connected to the tachometer, the next step is to wire the ignition switch and coils. These wires will also be either red or black, depending on the brand, and they should be connected to the same terminals as the ones connected to the battery. The power and ground wires should be connected to the coil and the trigger wire will connect the tachometer to the distributor.



Setting Up Illumination


Most Evinrude tachometers come with an additional set of wires specifically for illumination. These wires – typically brown, blue and yellow – should be connected to the appropriate terminals on the back of the tachometer. Finally, if there is an additional ground wire, it should be connected to a clean metal surface on the engine block.



Conclusion


Evinrude tachometer wiring diagrams are a valuable resource when installing and connecting a tachometer to an engine. Understanding the different wires and their corresponding functions is the most important part of the installation process, and these diagrams are designed to make this task as easy as possible. Following these directions carefully can ensure that everything is connected correctly, leading to fewer problems and more accurate readings.
