Should you’re having bother along with your John Deere using mower, one of many first issues it is best to verify is the solenoid. A solenoid is a tool that makes use of electrical energy to create a magnetic subject, which in flip strikes a metallic plunger. This plunger is what engages the starter motor, so if the solenoid is just not working, your mower won’t begin.
There are just a few alternative ways to check a solenoid. A method is to make use of a multimeter to verify for continuity. To do that, set the multimeter to the ohms setting after which contact the probes to the 2 terminals on the solenoid. If the solenoid is working, the multimeter will present a studying of zero ohms. One other approach to take a look at a solenoid is to make use of a jumper wire. To do that, disconnect the wire from the solenoid that goes to the starter motor after which contact the jumper wire to the terminal on the solenoid that the wire was related to. If the solenoid is working, the starter motor will interact and the mower will begin.
If in case you have examined the solenoid and it’s not working, you’ll need to exchange it. Changing a solenoid is a comparatively easy process, however it is very important just remember to get the proper solenoid on your mower. You could find the proper solenoid by trying up the mannequin variety of your mower within the John Deere elements catalog.
