Understanding the Ignition Switch
An ignition switch is a critical component in the starting system of a mower. It is responsible for controlling the electrical current that allows the engine to start and run. A 6 prong ignition switch typically has multiple functionalities, including starting the engine, powering the ignition system, and controlling the lights and accessories.
Components of a 6 Prong Ignition Switch
The 6 prong ignition switch consists of several key components:
1. Switch Body: The central part that houses all the internal connections.
2. Prongs: Six metal contacts that connect to various electrical components.
3. Key Lock: A mechanism that allows the operator to turn the switch on or off.
4. Housing: The outer casing that protects the internal components.
5. Wiring Harness: The collection of wires that connect the switch to the mower's electrical system.
Wiring Diagram Overview
The wiring diagram for a 6 prong ignition switch can often be found in the mower's user manual or service guide. It illustrates how each prong corresponds to specific functions. Here’s a general overview of the common prong assignments found in a typical 6 prong ignition switch:
- Prong 1: Battery (B) - Connects to the positive terminal of the battery.
- Prong 2: Ignition (I) - Supplies power to the ignition coil.
- Prong 3: Starter (S) - Engages the starter motor.
- Prong 4: Accessory (A) - Powers additional accessories like headlights.
- Prong 5: Ground (G) - Connects to the mower's ground system.
- Prong 6: Kill switch (K) - Cuts power to the ignition coil to stop the engine.
Wiring the 6 Prong Ignition Switch
Properly wiring a 6 prong ignition switch is crucial for the functionality of your mower's engine. Follow these steps to ensure correct installation:
Tools and Materials Needed
Before you begin, gather these tools and materials:
- Screwdriver (flathead and Phillips)
- Wire stripper/crimper
- Electrical tape
- Multimeter (for testing connections)
- Wire connectors
- New 6 prong ignition switch (if replacing)
Steps to Wire the Ignition Switch
1. Disconnect the Battery: Always start by disconnecting the battery to prevent any electrical shorts or shocks.
2. Identify the Wires: Refer to the wiring diagram specific to your mower model. Color coding can help, as many manufacturers use standard color codes.
3. Connect the Battery Wire: Connect the wire from the battery to prong 1 (Battery). This wire is typically red.
4. Ignition Coil Connection: Attach the wire leading to the ignition coil to prong 2 (Ignition). This wire is often yellow or orange.
5. Starter Motor Connection: Connect the starter motor wire to prong 3 (Starter). This wire is usually green or blue.
6. Accessory Wiring: If your mower has lights or other accessories, connect the wire to prong 4 (Accessory). This wire can be brown or black.
7. Ground Connection: Connect a wire to prong 5 (Ground). This is usually a black wire that connects to the mower's chassis.
8. Kill Switch: Finally, connect the kill switch wire to prong 6 (Kill switch). This wire is often white.
9. Double-Check Connections: Before reassembling everything, double-check all connections for tightness and accuracy.
10. Reconnect the Battery: Once everything is connected properly, reconnect the battery.
11. Test the Ignition Switch: Turn the key to the "on" position and check if the mower starts. If it does not, use a multimeter to check for voltage at each prong.
Troubleshooting Common Issues
Despite careful installation, issues may still arise. Here are some common problems and their solutions:
Engine Won't Start
- Check Battery Voltage: Ensure the battery is fully charged.
- Inspect Connections: Look for loose or corroded connections.
- Test Ignition Coil: Use a multimeter to check if the ignition coil is receiving power.
Starter Does Not Engage
- Starter Wire Connection: Ensure the wire connected to prong 3 is secure.
- Test the Starter Motor: Check the starter motor for functionality. It may need replacement if defective.
Lights Not Working
- Accessory Connection: Verify that the accessory wire is connected correctly to prong 4.
- Check for Blown Fuses: Inspect any fuses in the circuit that may have blown.
Maintenance Tips for Your Ignition System
To ensure the longevity and reliability of your mower's ignition system, consider the following maintenance tips:
1. Regular Inspections: Check wires and connections periodically for signs of wear and corrosion.
2. Clean Connections: Use a wire brush or electrical cleaner to remove corrosion from terminals.
3. Check Battery Condition: Test the battery regularly and replace it if it shows signs of weakness.
4. Store Properly: Store your mower in a dry place to prevent moisture damage to electrical components.
5. Follow Manufacturer Guidelines: Always refer to the owner's manual for specific maintenance schedules and procedures.
