Understanding Evinrude Outboard Ignition Switch Wiring Diagrams

Outboard motors have been used in boating to provide a reliable power source for many years. When it comes time to replace or repair your Evinrude outboard motor, understanding the wiring diagram is essential for a successful job. Knowing how to properly read wiring diagrams is essential for the safe and reliable operation of any outboard system.

The wiring diagram for an Evinrude outboard motor is divided into two main categories: ignition switches and other electrical components. Ignition switches are designed to control the flow of electricity from the starter circuit to the other components of the outboard such as the power trim, throttle controls, and other circuits. Other components such as rectifiers and relays also rely on the wiring diagram to provide power and ensure proper operation. In this article, we’ll further examine exactly how each component functions in the context of the Evinrude outboard motor wiring diagram.

The Starter Relay in the Evinrude Wiring Diagram

The starter relay is the component responsible for safely transferring electrical power from the starter battery to the starter motor. The starter relay contains an internal chemical switch that responds to signals from the on/off switch. The starter relay is connected to the main power feed and connects to the starter motor when the on/off switch is activated. When the relay senses the signal, it will quickly enable the starter motor to begin spinning the flywheel.

The Power Trim and Tilt Control in the Evinrude Outboard Wiring Diagram

The power trim and tilt control provides the means for changing the depth and angle of the boat within a specific range. This system is typically composed of two separate circuits: the power trim trim circuit and the power tilt control circuit. The power trim trim circuit senses an increase in speed or load and adjusts the outdrive as necessary to accommodate for the change. The power tilt control circuit moves the outdrive using a solenoid that is triggered by a manual switch or a dash-mounted joystick.

The Throttle Control in the Evinrude Outboard Wiring Diagram

The throttle control circuit is responsible for controlling the speed of the outboard. The throttle control circuit is composed of two main components: the throttle cable and the throttle control switch. The throttle cable connects the switch to the carburetor or fuel injection system, whereas the switch allows you to adjust the speed of the outboard motor by modulating the flow of air and fuel through the intake. The power of the motor is determined by the opening and closing of the throttle valve, which is regulated by the throttle control switch.

The Alternator Charge Circuit in the Evinrude Outboard Wiring Diagram

The alternator charge circuit is critical for keeping the electrical system running smoothly. The alternator charges the battery and also provides direct voltage to the starter motor and various other electrical components. The alternator consists of several parts including the stator, regulator, brushes, and diode board. The alternator circuit in the wiring diagram is composed of three main components: the voltage regulator, the alternator impeller, and the alternator field coils.

The Rectifier and Regulator in the Evinrude Outboard Wiring Diagram

The rectifier and regulator are responsible for converting alternating current into direct current. The rectifier converts the AC current into DC current, whereas the regulator maintains a consistent voltage output regardless of changes in demand. The regulator is also responsible for regulating the amount of power that is supplied to the starter motor and other vital electrical components. Both the rectifier and regulator are crucial components in any outboard wiring system.

Conclusion

Understanding and correctly interpreting the Evinrude outboard motor wiring diagram is essential for the safe and reliable operation of any outboard system. It is important to pay close attention to all the components, connections, and diagrams associated with the wiring diagrams. By doing so, you can ensure that everything works as it should and provide the safety and dependability expected from an Evinrude outboard motor.
