Briggs And Stratton 6 Terminal Ignition Switch Diagram

The ignition switch is a critical component in any Briggs & Stratton small engine, controlling the starting, running, and stopping of the engine. Understanding the Briggs & Stratton 6 terminal ignition switch diagram is essential for proper wiring, troubleshooting, and safe operation. This guide provides a comprehensive overview of the switch’s function, wiring, and practical application.

Benefits and Purpose of the Ignition Switch

The ignition switch offers several key benefits:

• Engine Control: Precisely manages the engine’s start, run, and stop functions.
• Safety: Provides a safety mechanism to quickly shut down the engine in emergency situations.
• Circuit Management: Controls various electrical circuits within the small engine system, including the starter motor and charging system.
• Preventing Unauthorized Use: Acts as a deterrent against unauthorized operation, particularly when combined with a key.

Understanding the 6 Terminal Ignition Switch Structure

The Briggs & Stratton 6 terminal ignition switch typically consists of these key components:

• Terminals: Six terminals, each designated for a specific electrical connection. These terminals are often labeled (e.g., B, S, M, L, G) to aid in proper wiring.
• Switch Body: The housing that contains the internal switching mechanism.
• Key Cylinder (if applicable): A cylinder that accepts a key to activate the switch.
• Contacts: Internal contacts that make or break electrical circuits depending on the switch position.

A typical wiring schematic associates the terminals with these functions:

• B (Battery): Connects to the positive (+) terminal of the battery.
• S (Starter): Connects to the starter solenoid.
• M (Magneto): Connects to the magneto or ignition coil to ground the ignition for stopping the engine.
• L (Lights): Connects to the lights circuit (if equipped).
• G (Ground): Connects to ground.
• A (Accessory): Connects to an accessory circuit that may remain on when the engine is off.

Practical Application

Proper wiring of the Briggs & Stratton 6 terminal ignition switch is crucial for engine operation. Here’s a simplified procedure:. For more related activities, check out our 2001 Ford Ranger Ignition Switch Wiring Diagram.

1. Identify Terminals: Carefully locate and identify each terminal on the switch using the Briggs & Stratton 6 terminal ignition switch diagram specific to your model. Refer to the engine’s service manual for accurate identification.
2. Connect Battery (B): Connect a wire from the positive (+) terminal of the battery to the ‘B’ terminal on the switch.
3. Connect Starter (S): Connect a wire from the ‘S’ terminal to the starter solenoid’s activation terminal.
4. Connect Magneto (M): Connect a wire from the ‘M’ terminal to the magneto or ignition coil grounding point.
5. Connect Lights (L): If your engine has lights, connect a wire from the ‘L’ terminal to the lights circuit.
6. Connect Ground (G): Connect the ground wire to the ‘G’ terminal on the switch and to a secure grounding point on the engine.
7. Connect Accessory (A): If needed, connect a wire from the ‘A’ terminal to any accessories you wish to power.
8. Verify Connections: Double-check all connections against the wiring diagram before starting the engine.

1. Troubleshooting Common Ignition Switch Issues

• Engine Won’t Start: Check the battery voltage, starter solenoid, and ensure the ‘S’ terminal is properly connected.
• Engine Won’t Shut Off: Verify the ‘M’ terminal is correctly grounded when the switch is in the ‘Off’ position. Check the grounding wire for breaks or corrosion.
• Lights Not Working: Inspect the wiring to the ‘L’ terminal and the light bulbs themselves.
• Blown Fuses: Short circuits in the wiring or faulty components can cause fuses to blow. Identify and correct the short before replacing the fuse.

2. Tips for Working with Ignition Switches

• Disconnect the Battery: Always disconnect the negative (-) terminal of the battery before working on any electrical components.
• Refer to the Diagram: Always use the correct Briggs & Stratton 6 terminal ignition switch diagram for your specific engine model.
• Use a Multimeter: A multimeter can be used to test the continuity of the switch contacts and identify wiring issues.
• Inspect Wiring: Regularly inspect wiring for damage, corrosion, or loose connections.
• Proper Grounding: Ensure all ground connections are clean and secure. A poor ground can cause various electrical problems.

FAQs About Briggs & Stratton Ignition Switches

Q: How do I know if my ignition switch is bad?

A: Common signs include the engine not starting, not shutting off, or intermittent electrical issues. Use a multimeter to test the continuity of the switch in different positions.

Q: Where can I find the correct wiring diagram for my engine?

A: The wiring diagram can usually be found in the engine’s service manual or on the Briggs & Stratton website by searching with your engine model number.

Q: What does each terminal on the 6-terminal switch typically do?

A: B is for Battery, S is for Starter, M is for Magneto, L is for Lights, G is for Ground, and A is for Accessory. The exact functions can vary by model, so always consult the wiring diagram.

Q: Can I use a different type of ignition switch as a replacement?

A: It is strongly recommended to use the exact replacement part or a part specifically designed to be compatible with your engine. Using an incompatible switch can damage the engine’s electrical system.

Conclusion

Understanding the Briggs & Stratton 6 terminal ignition switch diagram is crucial for maintaining and repairing your small engine equipment. By following this guide and using the correct wiring diagram, you can confidently troubleshoot and resolve ignition switch-related issues, ensuring safe and reliable operation of your engine.
