Murray riding lawnmower solenoid test

Assuming it is equipped with a Briggs & Stratton: Fuel solenoid test: Unclip wiring harness and remove solenoid from carburetor float bowl. Take a charged 9 volt battery, and touch two leads from the battery terminal to the solenoid terminals (polarity doesn't matter). You should hear an audible click as it engages, on some models you can actually see the solenoid plunger retract under power. If nothing happens, replace solenoid.
