How to Troubleshoot a Simplicity Starter Solenoidby Breann Kanobi
Simplicity lawn mowers use a starter solenoid that sometimes suffers from problems. To determine whether the problem is the starter solenoid or another part of the lawn mower, test the solenoid's voltage reading with a multimeter. This troubleshooting process fixes simple solenoid problems. Typically, the easiest course of action when dealing with a completely broken solenoid is to replace it. As of February 2011, you can purchase a Simplicity starter solenoid for about $10.
Locate the solenoid starter of your Simplicity lawn mower. In most Simplicity lawn mowers, the solenoid is under the front cover or hood, near the battery. Locate the positive battery cable and starter cable that are attached to the solenoid. These cables are red. Remove the starter cable using a wrench.
Turn your multimeter to 20 volts. Turn the Simplicity lawn mower on and touch the black probe of the multimeter to the lawnmower chassis. Touch the red probe of the multimeter to the post of the battery cable. Note the reading. It should be around 12 volts.
Pull the red probe from the battery cable and touch it to the side of the solenoid, in the place left by the removed cable. Check the voltage. A reading of zero indicates that your solenoid is busted.
Remove the solenoid if it is busted. Turn off the lawn mower and pull the key from the ignition. Disconnect the battery cable from the solenoid. Disconnect the clip wire of the wire harness using a screwdriver. Unscrew the mounting bolts using a wrench and remove the solenoid.
Reconnect the cables if the solenoid is not busted. Tug gently on cables to ensure that they are properly in place. Loose cables can cause solenoid problems.
