As a boat owner, there’s nothing worse than a faulty starter system. If you’re having trouble starting your Johnson outboard motor, the problem could lie in the starter solenoid or its wiring. In this article, we’ll explore the ins and outs of Johnson outboard starter solenoid wiring diagrams, so you can diagnose and troubleshoot any issues with your motor.
What is a Starter Solenoid?
A starter solenoid is a small electromechanical device that serves as a switch to power the starter motor of an outboard motor. The solenoid performs two functions:
- It connects the battery to the starter motor.
- It provides a high current to the starter motor, so it can turn the engine over.
The starter solenoid is activated when the operator turns the ignition key, and it sends a signal to the starter motor to turn over. If the solenoid or its wiring is faulty, the motor won’t start.
Johnson Outboard Starter Solenoid Wiring Diagram
Every Johnson outboard motor is different, so it’s important to refer to the appropriate wiring diagram for your specific model. However, all Johnson outboard starter solenoids have the same basic wiring diagram:
| Wire Color | Description |
|---|---|
| Red | Connects to the positive terminal of the battery. |
| Purple | Connects to the starter motor. |
| Yellow | Connects to the ignition switch. |
| Black | Connects to the ground. |
Red Wire
The red wire is the positive wire that connects to the battery. It should be connected to the positive battery terminal using a ring terminal. It’s important to make sure the connection is clean and tight.
Purple Wire
The purple wire connects to the starter motor. It should be connected to the starter motor using a spade terminal. It’s important to make sure the connection is clean and tight.
Yellow Wire
The yellow wire connects to the ignition switch. It should be connected to the ignition switch using a spade terminal. It’s important to make sure the connection is clean and tight.
Black Wire
The black wire connects to the ground. It should be connected to a clean, bare metal surface on the boat using a ring terminal.
Frequently Asked Questions
How do I know if my starter solenoid is faulty?
If you turn the ignition key and the engine doesn’t turn over, it could be a sign that the starter solenoid is faulty. You can also perform a voltage test on the solenoid to determine if it’s working properly.
Can I replace the starter solenoid myself?
Yes, you can replace the starter solenoid yourself, but it’s important to refer to the appropriate wiring diagram for your specific Johnson outboard model. It’s also important to disconnect the battery before working on the starter system.
What tools do I need to replace the starter solenoid?
You’ll need a socket set, a screwdriver, pliers, and a wire stripper/crimper to replace the starter solenoid. It’s also a good idea to have a multimeter on hand to test the voltage and continuity of the wiring.
How can I prevent starter solenoid issues?
The best way to prevent starter solenoid issues is to keep your Johnson outboard motor properly maintained. That includes regular oil changes, fuel system maintenance, and overall inspections. It’s also important to make sure the battery and charging system are working properly.
What should I do if I’m still having starter system issues?
If you’re still having starter system issues after checking the solenoid and its wiring, it may be time to take your Johnson outboard motor to a professional mechanic. They can diagnose and repair any issues with the motor’s starter system.
Conclusion
By understanding the basics of Johnson outboard starter solenoid wiring diagrams, you can troubleshoot any issues with your motor’s starter system. Remember to refer to the appropriate wiring diagram for your specific model, and always perform any repairs or replacements with the appropriate tools and safety precautions. By keeping your motor properly maintained, you can keep it running smoothly for many boating seasons to come.
