Johnson Outboard Key Switch Wiring Diagram

The Johnson outboard key switch wiring diagram is a simple yet essential component of your boat's electrical system. It provides a way to turn the engine on and off, as well as control other electrical accessories such as the lights and horn. This article will provide you with a detailed look at the Johnson outboard key switch wiring diagram, including a description of the different components and how they work together. We'll also cover some common problems with the key switch and how to troubleshoot them. ### Key Switch Components The Johnson outboard key switch is a simple device that consists of a few basic components. These include: * A key switch housing * A key switch plunger * A set of contacts * A spring The key switch housing is the main body of the switch. It is typically made of plastic or metal and houses the other components. The key switch plunger is a small metal rod that is attached to the key. When you turn the key, the plunger moves up and down, which activates the contacts. The contacts are small metal pieces that connect when the plunger is in the up position. This allows electricity to flow to the engine and other electrical accessories. The spring is a small metal coil that helps to return the plunger to the down position when you release the key. ### Key Switch Wiring Diagram The Johnson outboard key switch wiring diagram is a simple schematic that shows how the different components of the switch are connected. The diagram typically includes the following elements: * The battery * The starter solenoid * The ignition coil * The lights * The horn The battery is the source of power for the key switch. The starter solenoid is a switch that engages the starter motor when you turn the key. The ignition coil generates the spark that ignites the fuel in the engine. The lights and horn are connected to the key switch so that you can turn them on and off. ### How to Troubleshooting a Johnson Outboard Key Switch If your Johnson outboard key switch is not working properly, there are a few things you can check to troubleshoot the problem. * First, check the battery to make sure it is properly connected and has a good charge. * Next, check the starter solenoid to make sure it is working properly. You can do this by turning the key to the start position and listening for a click. If you don't hear a click, the starter solenoid may be faulty. * Finally, check the ignition coil to make sure it is generating a spark. You can do this by removing the spark plug wire from the spark plug and holding it close to the engine block. Turn the key to the start position and watch for a spark. If you don't see a spark, the ignition coil may be faulty. If you have checked all of these things and the key switch is still not working, you may need to replace it. ### Conclusion The Johnson outboard key switch is a simple but essential component of your boat's electrical system. By understanding how it works and how to troubleshoot it, you can keep your boat running smoothly.
