An electric lawn mower uses electricity to drive the motor that spins the blades to cut grass. You can test the current flowing through the lawn mower by hooking a multimeter to it. Multimeters are available in a hobby shop or electronics store. The lawn mower's power switch needs to be partially disassembled to run this test.
Instructions
1 Disconnect the power cord from the electric lawn mower from the AC outlet. Place the cable at your side so that it cannot be accidentally plugged in again.
2 Loosen the two screws on the power switch on the lawn mower handle-use a Phillips jewel screwdriver or Torx driver to do this, depending on the machine manufacturer. Pull the handle switch.
3 Turn the knob on the multimeter to be against the "ohm" labeled text. Place one of the two probes connected to the multimeter against one of the two screws on the switch that has electrical wires wrapped around it. Place the other probe of the multimeter against the other screw.
4 An assistant plug the Lawn mower power plug into the outlet and activate the power switch on.
5 See the needle on the back and forth multimeter Swing on the panel. Let the needle settle so that the tip can be read against the numbers printed on the scale on the panel. If a reading of approximately "0" (zero) is being read by the needle, the current is passed through the electrical wires; If the reading is not more or less "0" (zero), then there is a problem with the electrical cables and you have to fix the mower to discover the origin of the problem.
6 make the wizard turn off the switch. Remove the probes from the switch. Disconnect the power cord from the lawn mower from the outlet. Replace the switch on the handle.
