When I attempt to start my mower when i turn the start key it just clicks (at the start button). Everything is set and/or disengaged (mower, brakes etc). The solenoid (if there is one does not click or engage. I have checked the fuses that i could find. The battery is fine, I even went so far as putting a jumper from my truck and it's the same as above. Could it be the switch itself and how could I check it in place?
