Evinrude ignition switch wiring diagram is a crucial component for the proper functioning of your boat’s engine. The ignition switch connects the starter motor to the battery, allowing you to start the engine. If there is a problem with the ignition switch, it can prevent your boat from starting, leading to significant issues. In this article, we will discuss everything you need to know about Evinrude ignition switch wiring diagram, including the working principle, wiring diagram, and frequently asked questions.
Working Principle of Evinrude Ignition Switch
The working principle of the Evinrude ignition switch is relatively simple. The switch has several connectors, each connected to a different component of the engine. When you turn the key in the ignition, it completes the circuit and sends power to the appropriate component, enabling the engine to start. When you release the key, it springs back to the “run” position, allowing the engine to continue running.
The Evinrude ignition switch also has a safety feature built-in, preventing the engine from starting if it is in gear. This safety feature prevents the boat from lurching forward or backward when starting, which can cause significant damage or injury.
