how to check ign switch on 318 john deere

When it comes to ensuring your John Deere lawnmower is running optimally, one of the most important components to check is the ignition switch. The ignition switch provides the power necessary for the engine to start. Without it, you will be unable to get your mower moving. Checking the ignition switch on a John Deere 318 Lawn Mower is a relatively straightforward process and one that can be completed quickly with the right tools and materials.

The first step in checking your ignition switch is to locate it; this is usually underneath the seat of the mower. To access the switch, you will need to carefully remove the seat. Once the seat is out of the way, you should be able to easily spot the switch. It should have three wires running to it; two from outside sources and one running to the starter. Before proceeding, ensure that the engine is off and that the key is removed.

Now that the switch has been located, you can begin the diagnostic process. The easiest way to do this is to use a multimeter to test the voltage that is being supplied to the switch. Connect the meter to the two external wires and set the meter to DC voltage. If the voltage reading is lower than it should be, then the connection is faulty. If everything appears to be normal, then it’s time to check the internal connection. This is done by connecting the meter to the center wire and again setting it to DC voltage. If the meter shows a lower than expected reading, then the internal connection is faulty.

By following these steps, you can easily check the ignition switch on your John Deere 318 Lawn Mower and determine whether any repairs are needed. If the results suggest that the switch is defective, then a replacement will be necessary. Once the issue has been identified and fixed, you can then get back to mowing your lawn and enjoying your outdoor space!
