how to test ignition switch lawn tractor

As the name suggests, an ignition switch is an electrical device that starts the engine of a riding lawn mower. The switch can be used to control different electrical functions such as turning on or off the headlights, turning on the fan, and engaging the blades. The ignition switch on a lawn tractor is an essential component that can be damaged over time and will require replacement. To ensure that your mower runs smoothly, it's essential to know how to test the ignition switch regularly. This article will guide you on how to test the ignition switch, and we've included a step-by-step guide below.

Step 1: Safety first

Before you start testing your ignition switch, it's essential to ensure that all the safety measures are in place. Take out the ignition key from the switch and disconnect the battery cables to prevent any accidents. The safety switch likes to kill the engine when there's no driver in the seat. So, before you test the ignition switch, sit in the seat to activate the safety switch. This prevents the engine from starting as soon as you test the switch.

Step 2: Check for continuity

To test the ignition switch, you'll need a multimeter. A multimeter is an electronic measuring device that measures voltage, amperage, and resistance. Start by checking the continuity of the ignition switch by connecting the multimeter probes to the switch's terminals. Turn the key to the \"ON\" position and check the reading on the multimeter. If the multimeter readings show good connectivity, it means the ignition switch is not damaged. If there's no connection, it's time to replace the ignition switch.

Step 3: Check the resistance

If you're still getting voltage readings, you should check the resistance of the ignition switch. To do this, place one probe on the positive terminal of the ignition switch and the other on the negative terminal. Next, turn the key to the \"START\" position and check the multimeter readings. If the reading is at zero, it means the switch has continuity and is working correctly. If the meter shows an infinite value or is above 12, then the ignition switch needs to be replaced.

Step 4: Checking for voltage

The final step in testing the ignition switch is to check for voltage. First, connect the probes of the multimeter to the switch's battery terminals. Turn the key to the \"ON\" position and check the multimeter's reading. You should see a voltage reading higher than 12 volts. If you don't get a reading, then the switch is faulty, and you should replace it.

Conclusion

In conclusion, checking the ignition switch of your lawn tractor is essential to keeping it running smoothly for years to come. Understanding how to test the switch is relatively easy with the help of a multimeter. It's important to remember that safety comes first, so make sure you take all the necessary precautions when testing the ignition switch. If you're unsure of the process, it's always a good idea to ask for professional help. Regular maintenance testing will help you avoid costly repairs and ensure that your riding lawn mower runs efficiently and safely.
