A neutral switch is located on the lower end of both drive control handles and is activated when the handles are outward in the neutral position. Check that the plunger buttons on both switches are depressed at least 3/8”. Meter should go to zero when checking continuity across switch terminals with plungers depressed. If any of the switches in this circuit tested bad, install a new With PTO switch in one and perform Test #4 again. If all switches are good, a the off position, meter co

ENGINE CRANKS BUT WON’T START Checks for electrical problems •While turning ignition switch to its first position, listen for the fuel solenoid on the carburetor to click. It must click to supply fuel to the carburetor. •Try a new spark plug. •Check for spark at plug when it is removed and the threaded end is grounded. •Unplug the six-position socket that connects engine wiring to mower wiring harness. Engine will still crank. If plug doesn’t have a spark now, ignition module is probably defe
