I have a 2005 Hustler Super Z 72" with the 28hp EFI Kohler. 2 weeks ago, I turned the engine off for a brief moment while talking to someone. When I went to start it, I received a loud click then nothing. Fans are not running with the key on, PTO clutch is not engaging, engine lights on the panel are not lighting up....completely dead. Checked all fuses (3 on the panel and 2 behind the seat), nothing is blown. I have power to the ignition switch so i assumed it was possibly the switch. Replaced switch today after work and still no go. Battery is good. It was replaced at the beginning of this year and hasn't given me issues. What am I missing? What would cause everything to completely die at once?
