Understanding your Evinrude outboard motor's electrical system is crucial for proper maintenance and troubleshooting. A key component in this system is the ignition switch. This article will delve into the intricacies of the Outboard Motor Evinrude Ignition Switch Wiring Diagram, explaining its purpose and how to interpret it. Having a clear grasp of the Outboard Motor Evinrude Ignition Switch Wiring Diagram can save you time and money when dealing with electrical issues.
Understanding Your Evinrude Ignition Switch Wiring
An Outboard Motor Evinrude Ignition Switch Wiring Diagram is essentially a blueprint for how your ignition switch connects to the rest of your outboard motor's electrical components. It visually represents the wires, their colors, and the terminals they attach to on the switch and other parts of the engine. This diagram is invaluable for anyone needing to replace an ignition switch, diagnose a starting problem, or even install accessories that draw power from the ignition system. The information contained within this diagram is essential for ensuring your outboard operates safely and efficiently .
The ignition switch itself typically has several positions, such as OFF, RUN, START, and sometimes ACCESSORY. Each position connects different circuits within the outboard. For example, in the OFF position, all circuits are broken. In the RUN position, power is supplied to the engine's ignition system and other essential components. The START position engages the starter motor. A typical wiring diagram will show:
- The main battery positive (+) terminal connection.
- Connections to the ignition system (CDI module, coils).
- Connections to the starter solenoid.
- Connections for any accessories that are powered when the key is turned.
Interpreting the diagram involves following the lines that represent wires. Each line will connect a terminal on the ignition switch to a specific component. Wire colors are also usually indicated, which is a critical piece of information for accurate connections. Here's a simplified breakdown of common terminal functions you might see on an Evinrude ignition switch diagram:
| Terminal Label | Function |
|---|---|
| B (Battery) | Direct connection to the positive battery terminal. |
| S (Start) | Engages the starter solenoid. |
| I or IGN (Ignition) | Powers the ignition system in the RUN position. |
| A (Accessory) | Powers accessories when the key is in the RUN or ACC position. |
| M (Magneto/Kill) | Connects to the ignition system's kill circuit. |
